The third Dry-farming Congress was held February 23 to 25, 1909, at Cheyenne, Wyoming, under the presidency of Governor W. W. Brooks of Wyoming. An unusually severe snowstorm preceded the Congress, which prevented many from attending, yet the number present exceeded that at any of the preceding Congresses. This Congress was made notable by the number of foreign delegates who had been sent by their respective countries to investigate the methods pursued in America for the reclamation of the arid districts. Among these delegates were representatives from Canada, Australia, The Transvaal, Brazil, and Russia. The fourth Congress was held October 26 to 28, 1909, in Billings, Montana, under the presidency of Governor Edwin L. Morris of Montana. The uncertain weather of the winter months had led the previous Congress to adopt a time in the autumn as the date of the annual meeting. This Congress became a session at which many of the principles discussed during the three preceding Congresses were crystallized into definite statements and agreed upon by workers from various parts of the country. A number of foreign representatives were present again. The problems of the Northwest and Canada were given special attention. The attendance was larger than at any of the preceding Congresses. The fifth Congress will be held under the presidency of Hon. F. W. Mondell of Wyoming at Spokane, Washington, during October, 1910. It promises to exceed any preceding Congress in attendance and interest. The Dry-farming Congress has made itself one of the most important factors in the development of methods for the reclamation of the desert. Its published reports are the most valuable publications dealing with dry-land agriculture. Only simple justice is done when it is stated that the success of the Dry-farming Congress is due in a large measure to the untiring and intelligent efforts of John T. Burns, who is the permanent secretary of the Congress, and who was a member of the first executive committee. Nearly all the arid and semiarid states have organized state dry-farming congresses. The first of these was the Utah Dry-farming Congress, organized about two months after the first Congress held in Denver. The president is L. A. Merrill, one of the pioneer dry-farm investigators of the Rockies. Jethro Tull (see frontispiece)
