10.2 Conditions under which analyses and tests will be made. The conditions under which the Bureau of Mines will, for a fee, analyze samples of coal and determine the softening temperature of coal ash are set forth below:

(a) Application for the making of such analyses and tests must be made to the Director of the Bureau of Mines, Washington, D. C.

Page 19

(b) The Bureau of Mines cannot undertake to make analyses of coals for private parties except in cases where good reason exists why such analyses should be made in a Government laboratory, as in cases where the coals are to be exported for sale in other countries, or in cases involving arbitration, and for other reasons.

(c) In order that the analyses and tests made by the Bureau may be fairly representative of the coal to be analyzed, it is essential that the sample of such coal be collected and shipped in the manner approved by the Bureau of Mines. (See method described in Technical Paper 1, The Sampling of Coal in the Mine, and Technical Paper 133, Directions for Sampling Coal for Shipment or Delivery.).

(d) Samples should be sent, transportation charges prepaid, to the Coal' Analysis Laboratory, Bureau of Mines, 4800 Forbes Street, Pittsburgh, Pa., and with each sample of coal should be furnished the name of the coal bed and of the mine from which the sample came. The location of the mine with respect to the State, county, and the shipping point or nearest town should be given.**

10.3 Remittances. After an applicant has received notice that samples of coal for analysis or test will be accepted from him, he should forward to the Bureau of Mines, Washington, D. C., a certified check, bank draft, or money order in payment of the specified fees. All such checks, drafts, or money orders must be made payable to the Treasurer of the United States and will be deposited in the United States Treasury through the disbursing officer of the Department of the Interior to the credit of miscellaneous receipts in accordance with United States Treasury regulations.**
