IfrlGate 4UO, UUU acres ShOQIQ Icdu from this reservoir and may also be used for navigation. The area mentioned is uncertain, and includes the land reclaimed by the lower reservoir. Investiga ton may also show that from thi3 dam it will be feasible to carry canal through a tunnel into the great Colorado desert l in California;; but this is very 1 uncertain.
 (3,) Dam at Bulls Head, 100 feet high: to be reduced to 60 feet when the reservoir is filled | with sediment. It will probably l cost S2,O00,O09, and will water 30O,000 acres which can be con- manded when the cultivation of . the Bill Williams site begins.
 (4.) Dam in Black Canyon, 300 feet high. This will water 30, GOO acres above Bulls Head. and i furnish power for pumping i from it's own reservoir sufficient 1 water for irrigating 80,000 acres in Detrital Valley, Arizona, and | 10000 acres in Forlorn Hope | Valley, Nevada, making a total of 200, GOO acres. This reservoir 1 will be over 150 miles in length, i and together with those below will solve the problems as nearly as natural conditions permit for a century or more to come, and probably permanently. In case more storage capacity is re quired in the future. other res ervOirs with dams of moderate heightmay be constructed above Virgin river in the Canyon of the Colorado, each of which will furnish additional storage capac ity, additional power and addi tional navigation facilities.
 GREAT STORAGE CAPACITY.
 The plans mentioned, however, would provide a storage capacity equivalent to the width of the river channel, a length of 400 miles, and an average depth of perhaps 90 feet, or 1,600, GOO acre feet. The need of more storage capacity could only oc cur by the complet9 filling by silt of the last reservoir men tioned, which would mean the creation of several hundred thousand acres of rich farming land, the value of which would far more than pay for the addi- tional reservoir, and the same facts would apply to any addi- tiOnal storage required later.
 SOURCE OF VAST POWER.
 In addition to the power used for pumping water into Detrltal and Forlorn Hope valleys, there will be thus developed water to the extent of 500,00 horse power, the machinery for which can be installed as the demand for power arises. This power could and would be utilized eE tensively in the mining industry throughout the region under discussion, and for this purpose will be very valuable. For in stance it could be carried to the United Verde copper mine, one of the largest in the world, where fuelis very high, and where cleo tricity could be used not only for power but for reduction and re- tinement
 Where rich mines are opened, transportation to them becomes essential, and this power will be available for operating numer- ous trolley lines, which will be built. It will be available for operating the boats engaged up on the river, saving both the cost of coal and it's freight room.
 It will also be entirely practica-
 ble to transmit the power cleo trlcally to the Santa Fe Pacific railway at the Needles, and at Peach Springs, and to operate that system and it's branches from San Bernardino, Cal, to Winslow and Phoenix, Arizona,
 total length of line of nearly
 900 miles, beset by heavy grades,
