The following bridges were repaired with new stringers and redecked with 3-inch plank: Lost Creek, 18 foot span; Nameit Creek, 21-foot span; Clocktower 27-foot span, and another bridge over a stream on Sylvan Hill, 28-foot span.

On the West Gallatin Road four 30-foot and one 24-foot bridges were redecked with poles. Fourteen small log culverts, three 6-foot log culverts, and one 8-foot log bridge were rebuilt.

Road protection, Shoshone Forest.-As a means of protection to the roadway from the encroachment of the Shoshone River, the following work was done this year: Six hundred feet of embankment riprapped with large rocks near Grinnell Creek; 300 feet of embankment riprapped near Middle Creek; one log diversion crib, 8 feet wide, 9 feet high, and 24 feet long added to the present crib at Elk Fork; log diversion crib, 8 feet wide, 5 feet high, and 90 feet long, built opposite the mouth of Canfield Creek; log diversion crib,9 feet wide, 9 feet high, and 50 feet long, built at the Palisades.

Bechler River Road survey. As this report is written a preliminary survey is being made for a road up the Firehole River from Lone Star Geyser to the headwaters of the Firehole, thence down Little's Fork of the Bechler to Three River Junction, thence down the Bechler and Falls River to Cave Falls, near the south park line. With the park engineer and the chief ranger I rode over the route of this proposed road on August 22 and 23.

Parapets and guard rails.—The program started last year of building log guard rails and masonry parapets for protection along dangerous sections of the roads was continued this season. The greater part of the work done this year was at the Needles near Tower Falls, where the following work was completed: 54 masonry piers 20 by 20 inches were constructed, 288 20-inch log posts planted 36 inches in the ground, 4,576 linear feet of 9-inch guard rail placed on the piers and posts and 90 cubic yards of material moved to eliminate sharp curves. Between the 4 and 5 mile posts from Mammoth on the Tower Falls Road 1,136 linear feet of guard rail were built, requiring 81 20-inch log posts placed, 30 of which were set in concrete. Two hundred and seventy-five linear feet of guard rail were also built around the sharp curve above the Gardiner River Bridge.

NEW BUILDINGS.

The Lake ranger station and community center.-The third of a chain, which it is hoped to have throughout the park, is practically completed and will be ready for the 1923 season. The plans for this building, developed by the landscape engineering division of the Park Service, have given us a structure unique in type and at the same time well suited for its requirements. The large community room forms an octagon in plan which is slightly less than 40 feet across. In the center is a great stone fireplace, open on four sides, which will present a campfire effect. A wing 26 by 38 feet provides quarters for the rangers stationed at this junction, the space being divided into a combined kitchen and dining room, office, dormitory, and bath, with ample hall and closets. Logs have been utilized in the construction of the station with roof of sawed shakes and with a broad terrace of flat stones. The Lake Station has become one of the talked-of structures of the park.

Auto camp comfort stations.-A standard type comfort station has been prepared for auto camps in the park and this season will see the completion of at least three of these buildings, one at Yellowstone Lake and two at Old Faithful auto camp. The sanitary engineer of the Public Health Service and our master plumber worked in conjunction with our landscape division in an effort to secure a layout not only presentable from the landscape point of view but one which would be thoroughly efficient as well. The building at Lake measures 12 feet 6 inches by 22 feet and those at Old Faithful 17 by 25 feet. Both consist of separate compartments for men and women separated by a 3-foot space which is utilized for plumbing installation. The plumbing fixtures are of the latest approved type and these stations, forming a part of the new sanitary layout for the public auto camp, will be a much needed addition. The buildings are constructed with a frame of heavy logs which are exposed to weather. The walls are of rough boards and battens and the roof of shakes, this combination appearing well in the woods where they are located. Maintenance crew stations.-A small building 16 by 22 feet for use as a dining room and kitchen for the maintenance crew stationed at Dunraven Pass is under construction at the present time. This is a frame building with sawed shake roof. A similar building for the Cub Creek maintenance crew on the east approach road is being constructed on the banks of Cub Creek. This building is built of logs and is being ceiled inside in order that it may be used in winter as a snowshoe cabin by rangers patrolling between Lake ranger station and Sylvan Pass ranger station.

Lake engineer station alterations -The engineer station at Lake was improved by installation of more windows and by the erection of screens for doors and windows. Preparations have been made to chink the building. Another room will be added next year in order that this station may be used in winter as the Lake ranger station.

Repairs to penstock.-The steel penstock, 2,300 feet long, which conveys water from the reservoir to the power house at Mammoth was painted and placed on concrete piers to prevent deterioration by rust. The piers are 14 inches wide and are spaced 15 feet apart. Painting was done under the supervision of the master painter.

Landscape engineering activities.—Work by the landscape engineering division included the preparation of plans for buildings mentioned above, examination of plans and advice regarding location and erection of buildings by public utilities and individual operators, advice on painting, etc. Arrangements were also made, in the interest of the improvement of the landscape, for the removal of telephone lines and poles from certain sections of road where these lines and poles are too conspicuous. This work will be resumed before the opening of next season. Considerable work was done in the clearing of dead timber from roadsides. Several ugly entanglements of timber along the roads, thrown down by storm, were removed.

PROTECTION DEpartment.

Under the direction of the chief ranger a vast amount of tremendously important work was done in the protection department during the year. The ranger force was reorganized, many changes in personnel being made. Until June 15 the ranger force consisted of 1 chief park ranger, 3 assistant chief rangers, 1 fish and game warden, and 23 park rangers. During the summer this force consisted of 27 park rangers, includ

ing the chief ranger and his assistants, and 44 temporary rangers. Twenty-one ranger stations and 15 snowshoe cabins were in use during the year. A manual giving in detail the instructions for the ranger

force was issued in June.

Winter activities.-The winter activities of the ranger force were confined to the protection of the wild life of the park. During the spring months the rangers patrolled the roads to prevent washouts and made frequent reports on the melting of the snow. The condition of the wild life during the winter is reported elsewhere.

Summer activities.-During the summer the work of the ranger force was greatly expanded, comprehend. ing the protection of forests from fire, care of the wild life, checking of traffic at the gateways, protection of geyser and hot-spring formations, guiding tourists, operat.on of information office, lecturing, motor-cycle patrol of the roads, etc.

Forest fires.-There were few forest fires and none of these caused serious damage. During the latter part of June a fire burned into the park from the Madison National Forest, destroying approximately 80 acres of timber along the Madison River where this stream leaves the park. On August 14 a forest fire was caused by lightning on the Cody Road. The fire burned over 14 acres. Several small fires occurred but no great damage was done because of the prompt action taken by rangers and others.

New Soda Butte station.-A log structure of simple design prepared by the landscape division is under construction by the rangers at the Cooke City entrance to the park, replacing the old station located near the mouth of Soda Butte Creek. This building, combining a checking and ranger station, is situated on a beautiful wooded spot near the park boundary in such a way that a good view of approaching traffic may be had. The rough log type is used here with an effort to keep away from modern commercial mate rials. The building measures 22 by 34 feet, divided into large living room, kitchen, and dormitory, and in addition a porch extends across the entire end of the building.

Fish hatchery on Fish Lake.-The design of this building conforms with that of the new Soda Butte station and was erected by rangers during the month of May. The building is 18 by 24 feet with a 7-foot extension in front for a porch. The interior plans for the hatchery were prepared by Supt. W. T. Thomp son of the United States Bureau of Fisheries. All materials were furnished by the Bureau of Fisheries. Trail maintenance and improvement.-There are at the present time 791 miles of trails in Yellowstone National Park. Of these, 88 miles were constructed during the present year and 6544 miles were cleared of fallen timber, repaired, and maintained. New trails constructed included several sections of the Howard Eaton trail, the name given to the trail system paralleling the loop-road system. The trail was named in honor of Howard Eaton, pioneer guide of Yellowstone and famous game conservationist, who died April 5, 1922.

Fish planting.-One of the notable achievements of the year was the completion of the greatest fishplanting project ever undertaken in Yellowstone Park. The following is a summary of this work:

We are tremendously indebted to the Fish and Game Commission of the State of Montana for cooperation in these fish-planting activities, 1,000,000 black spotted trout fingerlings, 116,000 eastern brook fingerlings, and 120,000 rainbow trout fingerlings having been given to the park by the State in return for black spotted eggs collected here.

BUFFALO RANCH OPERATIONS.

The Buffalo Ranch is maintained for the care of the so-called tame buffalo herd. This herd at the present time numbers 578 animals. When last year's report was written there were 506 buffalo reported in the herd. Later 22 more calves of the 1921 crop were counted. Deaths and shipments during the year totaled 58 and there were 108 calves born in 1922. The 1921 calves were vaccinated November 25 and December 3 of last year. Of these 82 calves, 43 were male and 39 female; 27 of the males were castrated. Two of the female calves broke their legs during vaccination and were killed. Fifty-two buffalo died of hemorrhagic septicemia between March 18 and April 5. Of these, twenty-three were yearling bulls, nine yearling heifers, two 2-year-old bulls, seven 2-year-old heifers, one 3-year-old bull, six 3-year-old heifers, two 4-year-old cows, one 5-year-old cow, and one 10-year-old cow. Shipments of buffalo totaled 4. One bull and three cows 34 years old were shipped to the New York Zoological Park, New York, in charge of the chief buffalo keeper.

During the winter the herd was fed a total of 517 tons of hay, feeding starting on December 28, 1921, and ending April 24, 1922. Improvements at the Buffalo Ranch during the year include the cutting and hauling of 800 posts and fence rails to repair fences broken down by elk, clearing and plowing of 200 acres of land on Amethyst Creek, and the installation of new headgates in the lower hay meadows. Thirty headgates are to be installed, 15 being completed at this time.

HAY RANCH OPERATIONS.

The following table shows the hay fed at the various park ranches during the past winter and the approximate amount put up this season. As the greater part of this year's hay has not been in the stack long enough to measure it, it is not possible to give accurate tonnage at present.

During the year 154 predatory animals were killed, 24 wolves and 130 coyotes.

NATURAL FEATURES OF THE PARK.

The park naturalist and the rangers made observations of the wild-life conditions, geysers, forests, flowers, etc., and the following information regarding the natural features of the park is based on those observations: Game conditions.-Game conditions the past year have been excellent, with the exception of those affecting the antelope. In spite of the severe winter our loss in game animals was only slightly above normal and natural loss. The severe winter was disastrous to the antelope, about one-third of the herd being lost. Our forage is in fairly good condition this fall and all game should winter well, unless the winter is unusually

severe.

Tame buffalo. The condition of the herd of 578 so-called tame buffalo is covered in the paragraph relative to the Buffalo Ranch. Eighteen fine bulls of this herd were kept at Mammoth Hot Springs during the

summer season.

Wild buffalo. Unavoidable conditions made it practically impossible to make extensive observations of our wild buffalo herd. Thirteen were found in the Pelican Creek district and 56 along the Lamar River. One large bull was found dead at the mouth of Willow Creek. In addition to the 59 actually seen, signs were observed of a herd of about 50 on Cache Creek. I would place the number of animals in the wild herd at 125 to 150.

Mountain sheep.-Sheep scab, the disease that threatened for a time to exterminate our mountain sheep, has practically disappeared and we have a large, thriving herd of about 250 animals. They were seen in many different parts of the park last season, including the Bechler River district.

Antelope.-The most serious game problem in the park concerns the antelope. Unfavorable winter range conditions inside the park boundaries is the main cause of the rapid decline in numbers of this animal. Timid, nervous, and not naturally adapted to the area in which the settlement of the outside country has forced them, they are easy prey for coyotes and wolves and not physically able to withstand the severe winter elements. The herd consists of about 350 animals at present, of which 125 are this year's kids. Moose.-A severe blow was dealt to our moose herds last fall when the State of Wyoming authorized the killing of 50 bulls in the Upper Yellowstone country. This nearly exterminated the male moose on this area and has a much greater effect in that it will affect the calf crop during the next few years, as the bulls were killed before the rut. With the issuance of 50 additional permits for the coming season the days of the Upper Yellowstone moose may be considered numbered.

Moose are rapidly taking up range in other sections of the park and are thriving in regions where they are left undisturbed.

Deer-Only five white-tail deer were observed around headquarters during the past season. There are but few of this species in the park. Blacktail deer are very numerous in all sections of the park. One herd of 56 was observed at Gardiner last May and others of 15 to 40 seen frequently in various sections. There are over 1,000 of these animals in the park.

Elk-The northern herd of elk wintered well and there is a splendid calf crop this year. Bad snow conditions in the Jackson Hole were responsible for a heavy loss of calves in the southern herd. A show herd of 12 was inclosed during the summer near the buffalo corral for tourist enjoyment.

Black bears. Black and brown bears have been numerous in all parts of the park and around the garbage dumps at hotels and camps. Aside from a few stolen hams and other edible articles they have caused very little trouble during the past season. "Hold-up" bears have been active along the roads.

Grizzly bears. The grizzlies are seldom seen except at hotel garbage dumps. There is no doubt but that they are present in sufficient numbers to maintain their species in the park. As many as 16 were observed at the Canyon in one evening, and several at the Lake and Old Faithful.

Beaver.-Beaver are thriving in all sections of the park. Many new colonies have been established during the past year and their signs have been observed in many sections where they have never been known before. Rabbits and other small animals.-Rabbits are very numerous and often seen by persons driving at night. Woodchucks are getting more numerous every year. Several at the Canyon Camp have been petted, fed, and photographed by thousands of tourists the past summer. Ground squirrels are thriving and get to be a nuisance around the various buildings and road camps throughout the park. Pine squirrels, chipmunks, conies, and other small animals are thriving under park protection."

Birds. With the discovery and identification by Park Naturalist Skinner of the bobolink, ruddy turnstone, and white-faced glossy ibis, our list of park birds has increased to 205 species. Only about 70 are conspicuous enough to be noticed by our tourists.

Trees.-1922 was notable for the addition to our list of two new junipers, and a new broad-leafted cottonwood identified by our park naturalist.

Flowers.-Again we note that our visitors are becoming more and more keen on flowers, never fail to admire them, and are eager seekers of botanical lore. More than 50 varieties were added to our list, bringing it very close to a total of 700 species.

Grasses were badly injured by lack of rain in June, but recovered later at the higher elevations. This June drought cut down the early flowers perceptibly; but the more generous showers later caused an unusual rebirth, and later than usual, a wonderful display of fringed gentians. The scarcity of early rain combined with warm weather led most of our flowers to blossom very early.

GEYSERS.

During the winter of 1921-22 no very great changes occurred in either the Hot Springs or the Geyser Basins.

At Mammoth Hot Springs.-The Orange Spring developed a small opening on top of the mound from which a pencil-size stream of water constantly shot up 10 inches or more; activity and color increased at Minerva Terrace; Pulpit Terrace showed some wonderful growth and improvement, and the same is true of Jupiter Terrace; a fine spring and terrace started on the northern part of the old Marble Terrace in July and still continues to improve and increase in size; the spring near the old Cupid's Cave has opened again and is more active and more beautiful perhaps than ever before.

On August 14 one of the Roadside Springs had a violent eruption, threw out quantities of rock and mud, and deluged the road. More activity has since been shown, and has created a great deal of interest. It has been suggested that if this geyser action continues, it be called "The Semi-Centennial." This is the geyser that attracted so much interest as to be discussed in newspapers in all sections of the country. At Norris Geyser Basin.-Whirligig Geyser has been more active; the Constant Geyser has returned to its old regularity of one eruption every minute; Mud Boiler and the Valentine Geyser grew less and less frequent; the Bathtub was simply a boiling spring without geyseritic action. The Monarch Geyser did not play at all.

At Lower Geyser Basin.-All features remained normal. The Fountain Geyser played only once from the newer opening.

At Upper Geyser Basin.-Old Faithful played every 64.6 minutes until June 21, when the average period suddenly dropped to 60.5 minutes until July 5, when it rose again to 63 minutes and so continued until the end of the season, extreme periods were 36 and 82 minutes long; the Daisy played on an average every 75 minutes; the Grand every 11 hours; the Giantess played twice during the season and the Beehive only once; the Castle played well three or four times a week; the Giant was seen more than usual, about three times a month; the Lion, Grotto, Oblong, and Sawmill played frequently but irregularly; the Riverside was not quite so regular this year, varying from 6 to 8 hours with an average interval of 7 hours; the Fan and the Mortar did not play at all and both seem to be quite "dead"; the Lone Star continued to play every 2 to 3 hours.

At West Thumb.-The Lakeshore and one or two other small geysers played at times.

To sum up the season, I should say geyser activity, except the Giantess and Beehive, has been very vigorous indeed.

INFORMATION DEPARTMENT.

The museum, guide service and lecture service are all parts of the educational work being conducted in Yellowstone National Park in accordance with the policy of the National Park Service to make the parks mean more to the tourists from an educational standpoint. All of these services have been very popular with the tourists. The work of the information department is necessarily closely related to the work of the rangers and has been included above in connection with the discussion of what was accomplished in the protection department during the year.

Information office.-Thirty thousand two hundred and eighty-nine people visited the information office at headquarters during the summer-3,415 in June, 11,362 in July, 10,916 in August, and 1,495 in September. Compare the total of 30,289 with 24,443 visitors to the information office in 1921 and 9,918 in 1920.

A total of 3,954 Government publications relating to the park, including 944 National Parks Portfolios, and 632 other publications about the park were sold in the information office. A total of 31,945 free Government publications were distributed by this office and 62,000 free publications were given to visitors at ranger stations.

Museum. The room in the rear of the information office was fitted up as a museum, specimens of igneous rocks, geyserite, and petrified wood were installed, and the museum thrown open to the public on June 20, the opening day of the season. Although the men were kept busy on other work necessitated by the heavy rush of tourists, specimens of various kinds were collected, labeled, and installed throughout the season until now (September 20) there are 47 exhibits in the igneous rock case, 43 exhibits in the geyserite case, 41 exhibits in the petrified wood case, 2 mounted animal heads, 1 mounted eagle, a case illustrating beaver work and containing 4 exhibits, a contorted tree, 2 specimens of minerals, and 80 exhibits of pressed and dried flowers. To make the exhibits as interesting as possible, far more than the usual care was taken in the preparation of the descriptive labels.

Lecture service.-At Mammoth Hot Springs, Temporary Park Ranger Dr. F. E. A. Thone delivered a total of 232 lectures on the park, its geology, flora, fauna, history, etc. It is estimated that in his lectures Doctor Thone spoke to 60,000 tourists. Lectures were given at Mammoth permanent camp at 7.20; at Mammoth Hotel at 7.55, and before a bonfire in the public automobile camp at 8.30 each evening. From time to time lectures were also given in different parts of the park by the park naturalist.

Guide service.-Twenty-seven thousand one hundred and three people (337 guide parties) were guided by rangers over the formations at Upper Geyser Basin. At Mammoth Hot Springs 10,396 people were guided over the hot-spring terraces.

SANITATION DEPARTMENT.

Under the direction of the master plumber the extensive water and sewer system at headquarters was maintained during the year. A new heating plant with 1,000 feet of radiation was installed in the assistant superintendent's home. Boilers and radiation were also installed in the shops. Plumbing in the new ranger stations and community centers at Old Faithful and Grand Canyon were completed. Also the plumbing was nearly completed in the new Lake ranger station and community center and in the Lake comfort station. Water systems for new automobile camps were constructed as follows: At West Thumb, a reservoir with 8,000-gallon capacity and 8,000 feet of pipe line; at Madison Junction, a reservoir with 2,000gallon capacity and 3,000 feet of pipe lines to camp grounds; Mammoth automobile camp grounds, extension of pipe lines 2,000 feet: Tower Falls automobile camp, a powerful hydraulic ram installed, cement reservoir under construction, and pipe lines being laid as report is written. Also heating plant m post-office buildings and museum building being rebuilt.

Notable achievements in other sanitation work, through cooperation with Public Health Service officials, include construction of a sewerage system and disposal plants at Upper Geyser Basin to protect the Firehole River from pollution by raw sewage from Old Faithful Inn, the permanent camp, the auto camp, and the ranger station, the sewerage system requiring the laying of 3,650 feet of 6-inch, 1,250 feet of 8-inch, and 2,175 feet of 10-inch vitrified tile, and the disposal plants requiring two sedimentation tanks with apparatuses for sterilization of effluent; the construction of a sedimentation tank and sewer system for Canyon permanent camp; the construction of a sewer line for Lake Camp; field work completed for comprehensive sewerage system and disposal plants at the Lake to care for hotel, camp,auto camp, ranger station, and store. Similar work was done for the Canyon Hotel plant; also the beginning of drainage and other work for mosquito control at Old Faithful and Lake: study and location of water supplies for auto camps at Madison Junction, West Thumb, Canyon, and Tower Falls; bacteriological analyses of water and milk, 17 samples of milk and 84 water samples being analyzed during the season and several sources of drinking water being condemned

as a result thereof.

Dr. Harrison G. Dyar, of the Smithsonian Institution, export in mosquito control, and Mrs. Dyar, also an anthority on mosquitoes and their control, spent nearly a month in the park making collections of all species of mosquitoes and examining their breeding places. A comprehensive report was submitted describing the breeding places and the dominant varieties of mosquitoes. The report was couched in such directory language as to enable us to begin mosquito-control work in the form of drainage, filling low spots, or caling.

ELECTRICAL DEPARTMENT.

Electric system. The following table shows the total production of the power plant, disposition of current revenues, etc., as compared with similar data for the fiscal year 1922; The peak load for the year was 70 kilowatts.

A new

Telephone system.-The telephone lines of the park were maintained throughout the season. grounded wire line was built between the Lamar River Bridge and the lower hay ranch on Slough Creek, 7 miles. Also a line 3 miles in length was built from Dunraven Pass to the fire-lookout station on Moun Washburn. Nine miles of wire on Dunraven Pass and on the northern slope of Mount Washburn down as fara Haynes Tower Falls Picture Shop was removed and wire salvaged. An extra wire was strung between Norris Junction and Canyon Junction 11 miles in length. The total mileage of telephone wire is now 261 miles.

MECHANICAL DEPARTMENT.

The mechanical department maintained 17 trucks, & automobiles, a steam engine, a caterpillar engine, 3 steam rollers, compressors, pumps, etc.; repaired road machinery, including dump wagons, graders, 3 gravel loaders, drags, road tools, fire tools, etc. It also shod several hundred horses. It made the heavy hinges and locks for the doors of the new ranger stations.

The carpenter did miscellaneous work in the quarters at Mammoth, completed one new set of quarters in the old guardhouse at the south end of the old" Officers' Row," remodeled quarters assigned to the post office, shingled the plumbing shop and the assistant superintendent's quarters, laid new floors in two rooms of the superintendent's quarters, built toilet structures for auto camps, made signboards, etc.

A maximum of 12 men and a minimum of 6 were employed in the shops.

PROPERTY AND TRANSPORTATION.

Under the direction of the steward and master of transportation 711 tons of material, equipment, and supplies were moved from railroad terminals to headquarters. From headquarters 8 trucks were operated through the park, supplying read camps, construction camps, etc. The total mileage of the trucks was approximately 40,000. A maximum of 11 men were engaged in the warehouses and in transportation work.

PAINTING DEPARTMENT.

The master painter and his assistants completed the painting of most of the roofs of the wooden buildings of Fort Yellowstone. The exterior walls of several more buildings of the fort were painted. The residences of the United States commissioner and the assistant superintendent were painted. In the park the Tower Falls ranger station and the new ranger stations at Grand Canyon and Old Faithful were either painted or stained with creosote stain. Many trucks and wagons, including the sprinkler wagons, were painted and varnished.

Five hundred wooden signs were made and painted, including 300 trail signs; 300 steel signs were repaired and approximately 400 new steel signs were erected; 2,500 new boundary signs are being erected.

IMPROVEMENTS BY PUBLIC UTILITIES AND INDIVIDUAL OPERATORS.

Yellowstone Park Hotel Co.-An addition to the Lake Hotel was begun June 1. This annex will have 113 rooms and 59 bathrooms. A girls' dormitory of 58 rooms is under construction at Old Faithful, thus releasing for tourist use about 50 rooms in Old Faithful Inn. These rooms will be remodeled for tourists as soon as possible. Many other improvements were made by the hotel company, including painting of the exterior of the Mammoth Hotel, and the completion of the new dining room at Old Faithful Inn.

The hotel company had 810 cords of wood cut for Old Faithful Inn, and 535 cords for the Lake Hotel, and approximately 1,000 cords are being cut for the Canyon Hotel. All wood cut was dead or fallen timber. Yellowstone Park Camps Co.-At Mammoth 24 new cottages were constructed and furnished, together with additional washrooms and comfort stations to accomodate increased capacity. At Old Faithful 50 new cabins are in process of construction, which will increase the capacity of that camp more than 20 per cent. The new recreation pavilion was operated during the season and proved a successful addition to the entertainment features at the camp. A delicatessen tent, 20 by 40 feet, was constructed in the public automobile camp adjacent to Old Faithful Camp. This delicatessen served prepared cooked foods, such as soups, roasts, stews, hot biscuits, muffins, pies, and cakes; also fresh milk.

At Lake modern flush toilets were installed in the washrooms and the water supply system for camp was improved and enlarged. A women's dormitory with a capacity for 24 persons was constructed. At Canyon Camp a modern sewerage system for the scientific treatment of sewerage was installed and connected with flush toilets throughout the camp. Tub baths were also installed; two dormitories, each with a capacity for 24 employees, were built; 20 new cabins and 40 new tents are in process of construction. At Camp Roosevelt six log cabins of two rooms each and five frame cabins of two rooms each were constructed. The travel at the camp showed an increase of about 30 per cent over 1921.

Yellowstone Park Transportation Co.-This company puchased twenty-three 11-passenger busses and a new 5-ton truck with 1,200-gallon capacity, bought for hauling gasoline to various points in the park.
