ing reservoir and all diversion works 

 and canals above El Paso, is estimated 

 at $7,200,000, or $40 per acre for the 

 180,000 acres of irrigable land in the 

 valley. This is below the value of irri- 

 gated land in this section, and those 

 best informed pronounce the project 

 desirable at the price. The main item 

 of cost is the dam, which will require 

 500,000 barrels of cement and a large 

 amount of machinery, gates, etc., en- 

 tailing a very heavy outlay for freight. 



It is estimated that the dam will cost 



feet wide. The spillway is located at 

 a natural gap on the west side of the 

 valley several miles above the dam, 

 and about 175 feet above the level of 

 the present river bed at dam site. It 

 will have a length of 800 feet. 



At a public meeting recently held in 

 the valley a resolution was unanimous- 

 ly adopted declaring in favor of the 

 project and urging Congress to pass 

 legislation to enable lands in Texas to 

 be benefited by this reservoir and con- 

 tribute to its cost.

 jected the dam will be arched up- 

 stream and at six degrees curve, the 

 up-stream edge of the crest having a 

 radius of 955.4 feet. Its dimensions 

 are as follows: Height of dam from 

 bed rock foundation to top of parapet 

 walls or crest, 255 feet; thickness at 

 bottom, 1 80 feet; on top, 20 feet; 

 length of crest, 1,150 feet; the road- 

 way is 5 feet below the crest between 

 parapet walls on each side and is 14

THE superabundant and certain 

 sources of agricultural wealth 

 yet lying dormant in that part of Ore- 

 gon east of the Cascades are on the 

 eve of being developed on a scale in 

 keeping with their enormous extent. 

 Within this vast region, comprising 

 an area greater than several New Eng- 

 land states, the agricultural develop- 

 ment has been confined to isolated sec- 

 tions, which, by reason of their con-
