Get Ahead The dam is not com- 

 of High jleted, but excavation of 



the channel is finished 

 down to bed rock throughout the en- 

 tire length of the structure up and 

 down the stream. The rock walls and 

 bottom of the foundation consist of 

 the hardest of granite, absolutely with- 

 out seams. The canyon walls are saw- 

 tooth in shape, protruding into what 

 will be the masonry foundation of the 

 dam. The conditions developed make 

 the dam site one of the most favorable 

 that has ever been discovered. Con- 

 struction will begin on the masonry 

 at once. It is expected the contractors 

 will have the base of the dam up to 

 the original level of the stream well 

 in advance of high water, which 

 usually occurs in July. This is only 

 one of the construction features in- 

 volved in the Shoshone project. 



The 



Diversion 



Dams 



The Corbett tunnel was 

 completed November 29. 

 This tunnel has a ca- 

 pacity of 1,000 cubic feet of water per 

 second. The Corbett diverting dam 

 was finished January 4. The portion 

 of the project now completed includes 

 this diversion dam and the canal 

 which it supplies. The natural flow 

 of the river, without the regulation 

 supplied by the reservoir, will be more 

 than ample for several years to meet 

 the requirements of the land first irri- 

 gated. 



Another diversion dam at Will- 

 wood, six miles below the Corbett 

 dam, will conduct water through an- 

 other tunnel, on the south side of the 

 river, to irrigate the Willwood di- 

 vision, containing 25,000 acres. 



The 50,000-acre tract is bisected for 

 its entire length by the C, B. & Q. 

 Railway. Railroad stations are only 

 five miles apart, affording most satis- 

 factory transportation facilities for 

 the settlers and their farm products. 

 The first tract of 13,000 acres is al- 

 ready open to entry. The farm unit 

 area has been fixed at eighty acres for 

 most of the lands. A few of the farms 

 immediately adjacent to the towns 

 have been given forty-acre units. 

 With a number of the units, however, 

 is included a tract of eighty acres of 

 grazing land. 



For the 50,000 acres of land on the 

 Garland Canal, the complete irriga- 

 tion system will be completed during" 

 the calendar year 1908. Water will 

 be supplied May i to 13,000 acres. 

 There are already about 125 entry- 

 men on the 50,000-acre tract ; but this 

 does not exhaust the land available,, 

 since 50,000 acres are equal to over 

 600 eighty-acre farms. 



Costs to 

 Be Met 



The Land 

 Open for 

 Settlement 



The land to be irrigated 

 is from 4,000 to 5,000 

 feet in elevation. Its 

 quality is all that could be desired. 



The total cost of con- 

 structing the irrigation 

 system, including the 

 lateral distributory ditches and turn- 

 outs to each individual farm unit, 

 amounts to an average of $45 per 

 acre, which is payable in ten annual 

 instalments without interest. The total 

 charge, with deferred payments not 

 bearing interest, is equivalent to $30 

 paid down at the time of purchase, or 

 $30 payable by instalments drawing- 

 interest. 



It should be very carefully noted 

 that the Government's charges are all 

 based on deferred payments without 

 interest, which makes the cost very 

 easy for the settler. 



Further description of this project 

 and opening will be given in nex*- 

 month's magazine.
