Table of equivalents for the conversion of all fuels into terms of pounds of standard fuel-Continued. 1 Coal that contains more than 35 per cent of fine material which will pass through a 4-inch mesh wTWE shall be termed "slack coal.” Coal that does not contain more than 15 per cent of fine material which will pass through a 1-inch mea screen shall be termed "screened lump.” * Coal that contains more than 15 per cent and less than 35 per cent of fine material which will pas through a 4-inch mesh screen shall be termed “run-of-mine coal.” Wood that has been cut 6 months or more shall be termed "seasoned" wood. Wood that has been cut less than 6 months shall be termed "green" wood. The per cent ash and per cent volatile of coals, as shown in the above table, will be taken from the no tract and shall determine the classification of the coal throughout the delivery under that contract reced less of the results of analyses made from time to time. Where a contractor does not state the per cent ash and per cent volatile of the coal he proposes to deliver, the quartermaster shall ascertain the the ar mines from which the coal is obtained and report same to the Bureau of Mines, Washington, DC, wha request for statement as to the average per cent ash and per cent volatile content. Such percentages stal determine the classification of the coal throughout the delivery under that contract. Table of weights of wood per cord of 128 cubic feet. All wood shall be issued or sold by weight, as shown in the following table. Where wood is purett by the cord, the cost per pound will be found by dividing the cost per cord by the weight per cur-1 an wood purchased. Where mixed wood is purchased the per cent of each variety shall be estimated anİ the weight per cord calculated proportionately. 2553. In accordance with the provisions of paragraph 1036, Army Regulations, 1913, in so far as that paragraph relates to the reimbursement of officers and enlisted men on detached service in foreign cities and occupying quarters other than public, allowances for the zones of equal temperature established and previously referred to will be as follows: (G. O. 57, W. D., 1914; G. O. 40 and 65, W. D., 1915; G. O. 11, W. D., 1916.) 2554. Where officers or organizations occupy quarters at a military post for the entire fiscal year, accounting for fuel shall be made at the end of the fiscal year. When officers or organizations transfer from one military post to another during any fiscal year, accounting for fuel shall be made at the time of leaving the post or station. Savings in allowances for fuel will not be carried from one station or post to another, nor from one building to another at the same post. Allowances for a portion of a month will in all cases be determined by dividing the allowance for the month by 30 and multiplying by the number of days the building is actually occupied. An officer responsible for the fuel consumed in a public building, as shown in paragraph 2556, if relieved from such responsibility during the fiscal year, will make, at the time of his relief, a succinct explanation covering the conditions surrounding any excess of consump tion of fuel. The post commander will consider this explanation, bearing in mind the vagaries of the weather and the exigencies of the service, and will report the case, with his recommendations, to the department commander, who will determine whether or not relief from charge for the excess consumption will be granted. All excess consumptions under these provisions, and the action taken, will be reported to the Quartermaster General if, at the end of the fiscal year, an excess consumption should then appear for the building concerned. (G. O. 63, W. D., 1915.) 2555. To determine the rate to be charged for fuel consumed in excess of allowances where more than one type of fuel has been consumed, the rate to be charged will be found by the following method: Multiply the total quantity of each type of fuel consumed by its unit cost in terms of standard fuel and divide the total cost by the total weight of standard fuel. This will give the average unit cost per pound of standard fuel consumed. Multiply this cost per pound by the number of pounds of standard fuel consumed in excess of the total allowances. This will give the amount to be charged for the fuel consumed in excess of allowances. The following example is given: For a certain set of officers' quarters there are given allowances of 3,000 and 3,150 pounds of standard fuel for the months of January and February, respectively. If an officer occupies this set of quarters from January 4 to February 22, his allowance in terms of standard fuel would be 2,700 pounds for January, and 2,310 pounds for February, or a total of 5,010 pounds. Assuming that 5,500 pounds of anthracite egg coal at $6 per ton of 2,000 pounds and 2,000 pounds of seasoned oak wood at $5 per cord had been consumed during this period, the total consumption in terms of standard fuel would be 5,500 pounds times 1, or 5,500 pounds, plus 2,000 pounds times 0.40, or 800 pounds. A total of 6,300 pounds standard fuel has been consumed, or 1,290 pounds in excess of allowances. The rate to be charged for this fuel will be found as follows: First, convert the cost of each fuel into unit cost in terms of standard fuel. This will be done by dividing the unit cost by the per cent equivalent in all cases (except for wood when purchased by the cord) and reducing to unit cost. In the case of wood purchased by the cord the cost must first be reduced to cost by weight. This will be done by dividing the cost per cord by the weight per cord for the particular wood in question as given in the table of weights of various woods. This will give the cost per pound which will be converted to cost per pound in terms of standard fuel by dividing same by the per cent equivalent. By these methods the cost of each different type of fuel consumed in terms of standard fuel will be: For anthracite coal, egg, $6 divided by 1 equivalent, divided by 2,000 pounds, equals $0.003 per pound, and the cost of the amount consumed would be $0.003 times 5,500, or $16.50; and for seasoned oak wood, $5 per cord, divided by 3,850 pounds per cord, equals $0.00129 per pound actual weight, and $0.00129 divided by 0.40 equivalent equals $0.00322 times 800 pounds standard equals $2.58. The total cost of all fuel consumed would therefore be $19.08. Dividing the total cost of $19.08 by 6,300, the number of pounds of standard fuel consumed, the quotient will be $0.003029 per pound in terms of standard fuel and is the rate to be charged for all fuel consumed in excess of allowances. Since the total consumption for this period is 1,290 pounds in excess of allowance, the amount to be charged this officer for excess fuel will be 1,290 times $0.003029, or $3.91. The cost of each fuel will be based on the average annual contract price, plus freight charges, if any, plus the average cost of local delivery. This cost is to be determined at the beginning of the fiscal year, and will prevail throughout the term of the contract. In the above example it has been assumed that two different types of fuel have been consumed, in order that the method of computation may be illustrated. It will only be necessary to make these computations when allowances have been exceeded and a charge is to be made for such excess consumption. (G. O. 63, W. D., 1915.) 2556. The following table indicates the officer responsible for the fuel issued to various buildings at military posts, and for the fuel-consuming equipment therein. In case the fuel allowances in any building are exceeded the officer responsible for fuel consumption in that building will be held accountable |
