From Antofagasta, the expedition will travel by way of the Guggenheim mining properties to La Paz, Bolivia. From La Paz it will pass through unexplored territory, crossing the Andes at an elevation of more than 19,000 feet. Calomar will be used as a base for the expedition.

Emmons, University of Minnesota; Frank Hutchinson, consulting engineer, Duluth, Minn.; L. D. Davenport, mining engineer, Hibbing, Minn.; and W. H. Graigo, mining engineer, recently of South Africa, of the University of Wisconsin, will go to China this summer as consulting experts for the South Manchuria Railway company. The party will sail from Seattle early in June and return in October. Professor Mead writes:

The South Manchuria Railway company controls partly developed iron and coal deposits near Mukdan, South Manchuria. The iron deposits resemble geologically those of the Lake Superior region. The railway company has employed a group of technical men familiar with the Lake Superior iron mining industry to make a thorough investigation of the Manchurian deposits during the coming summer and to advise on the best methods of opening up and developing both the iron ore and the coal.

AMAZON An expedition to the headwaters of the Amazon River, under the leadership of Dr. H. H. Rusby, dean of the school of pharmacy of Columbia University, will sail for Antofagasta, Chile, on June 1. The main object of the expedition, which is financed by the H. K.

Dr. Frederick L. Hoffman, statistician and vice-president of the Prudential Life Insurance Company, will accompany the expedition to make a study of health conditions with a view to the possibility of the acclimatization of white men in the region.

constantly changing both in position and in intensity. Across these streamers, pale green pulsating clouds drifted, in general from north to south, but occasionally assuming a spiral form around the zenith. They attained their maximum brightness near the zenith where they were especially conspicuous on account of their almost instantaneous changes in intensity.

Bright colors were not noticed during the evening, but after the moon set about midnight, pale reds and blues appeared on the edges of the streamers and clouds. The display continued at intervals throughout the night. It was not more conspicuous in the north than in other directions.

The aurora was undoubtedly due to the very large group of sun-spots which had just passed the center of the sun's disk.


May 15, 1921

streamers were visible within a few degrees of the moon, which had just passed the first quarter. At this time a dark area a few degrees west of south on the horizon closely resembled an auroral arch, but a definite segment of a circle like that on the northern hori. zon could not be discerned

The shades, tints and hues, changeable and increasing from the beginning of the observation, now became more distinct and all of the primary colors appeared in varying degrees of intensity. Reappearing intermittently, the colors gradually faded away during the remaining hour of the display.



AGAINST a clear, moonlit sky, a brilliant auroral display was observed at Ames, Iowa, between 8:30 and 10:30 P.M. on May 14. The arch which was visible throughout this time except at short intervals, formed in our magnetic north and extended about 15 degrees above the horizon.

As the streamers, which were predominantly white, grew in number, in length and in extent along the horizon, they converged to a focus at a point somewhat variable in position but approximately 15° south and 5° west of the zenith, which point, the magnet zenith, became a center of radiation for the streamers. Abouth 15 minutes before the maximum development of the display, streamers of red were seen to rise from the horizon a few degreees south of east and to extend through the radiant center to the horizon about the same distance north of west, forming an arch along a magnetic parallel.

The maximum degree of brilliancy was attained at 9:27, when the streamers from a large coronal area formed about the magnetic zenith extended to the horizon in all directions, lighting the entire heavens. The radial

RUSSIAN GEOLOGISTS The sad fate that has befallen many of the leading Russian geologists and mineralogists constitutes a gloomy chapter in the history of these sciences. From particulars gathered by Professor Sederholm, of Sweden, and confirmed by a personal letter of March 30, 1921, received from Dr. Cornelius Doelter of Vienna, the following data have been secured.

Of some seventy Russian specialists in these fields eleven are dead. Of these, there died in Petrograd the well-known Professors Inostranzer, Fedorov (who died of hunger), Karakash, Derzhavin and Kasanski. Professor Sokolov died in Moscow. Professor Armasevski was shot in Kiev, as were Professors Samiatin and Mitkyevich in Petrograd. Stopnjevich died of smallpox and Snertkov of hunger-typhus. Baron Rebinder committed suicide, and it is reported that Faas is seriously ill.

AN AGE-COMPUTING DEVICE 1. In a recent issue of SCIENCE (1920, No. 1336, pp. 134_135), Dr. Slonaker describes a device for the simultaneous determination of the ages of two individuals at different times in their lives, involving the use of a calendar in which the days are numbered consecutively throughout the year. The present device obviates the need of the calendar and the need for resetting for dates in different years. As used with reference to human beings, two accessory scales aid in determining in years the age of an individual at different episodes in his life, when his present age and the years in which the episodes occurred are known, and vice versa.

the Bureau of Soils, United States Department of Agriculture. The Macmillan Company, New York. 1920. Pp. xviii + 399. Illustrations: 56 plates, general soil map of the Southern States (frontispiece), and four additional maps.

This book departs from the usual trend of books on soils in that instead of dealing with the properties and nature of soils in general the author describes the origin, geographic distribution, physical characteristics, agricultural adaptations and management of all the important soils occuring in the area under discussion. The states included in the work are those lying south of the north boundaries of Delaware, Maryland and West Virginia, south of the Ohio River, and south and east of and including Missouri, Kansas and Texas.

In the introduction the author explains the division of the country under consideration into soil provinces and subordinate soil regions, and describes the United States Bureau of Soils system of classification and nomenclature of soil series and types. The introduction further takes up the geographical distribution and in general the adaptation to different soils of the various crops grown in the South; and the influence of climate on soils and crops.

The general geography, topography, geology and agriculture of each soil province and its subordinate soil regions are discussed, followed by detailed descriptions of the individual soils. These descriptions include the location, physical and frequently chemical characteristics, topography, drainage and crop adaptation of each soil, and methods of soil management and fertilization which actual farm practise and experimentation have proven to be most effective.

Four appendixes include discussions of the meanings of terms used in soil classification, chemical analyses of representative southern soils, a bibliography of important publications on soils and related subjects, and statistics bearing on some of the important farm products of the southern states.

The book is valuable not only to students and agricultural investigators but also to
