About that time, however, the public began The first effort to give to the public a com to awaken to the realization of the need of prehensive description of the great coal-be~ing utilizing better the fuel supply and to the fur areas of the country was .made by the Geo ther realization that great cfrauds had been logical Survey in 1902, by the publication, in perpetrated in the Western States in procuring the Twenty-second Annual Report of the valuable coal lands under the h'omestead act Director, of 12 papers dealing with the coal and laws other than the coal-land law, which bearing areas of the United States, including required .the payment to· the Government of Alaska. Unfortunately, this series of papers, not less than $10 or $20 an acre and restricted although exceedingly interesting and valuabie to 160 aGres the area that it was possible for as presenting a .summary of the then existing one person to acquire.

This was made possible by a new Up to the year 1905 the United States Geo interpretation of the phraseology of the coal logical Survey had·' made no effort to examine land law of 1873, which· specified that· co~tl and map systematically the· coal fields of the lands should be sold at not less than $10 an country, especially of the West; but a number acre if more than 15 miles from any completed of fields had been specially examined or had railroad and not less than $20 an acre if within been n1apped as a part of the general plan of 15 miles of a railroad. 1 2 THE COAL FIELDS OF THE UNITED STATES.
