FORESTRY AND IRRIGATION 



May 



chemists, who will devote all their 

 time to standardizing the cement ma- 

 terials and testing the products of the 

 mill. It is expected that about 200,- 

 ooo barrels of cement will be required 

 in the construction of the Roosevelt 

 dam, the power canal, and the various 

 Tonto improvements. The cement 

 used in the preliminary work costs 

 $5.35 a barrel delivered at the point 

 where it was used. Bids were later 

 received for furnishing cement at 

 $4.81 a barrel. It will cost the Gev- 

 ernment $1.60 a barrel to make the 

 cement on the ground. If the cost of 

 the plant, $120,000, be added to the 

 cost of the 200,000 barrels of cement 

 required, the total cost of the Govern- 

 ment cement will still be only $2.20 

 a barrel. This means a saving of 

 $2.61 a barrel, or a saving of $522,- 



ooo on the entire work. After the 

 dam and canal have been completed, 

 the cement plant will still be capable 

 of further use, and considerable sal- 

 vage may doubless be realized. 



Two new gaging stations were es- 

 tablished on Little Colorado River 

 and its tributaries during March. A 

 party has been surveying a possible 

 power canal on Verde River, the pow- 

 er to be used to supplement that ob- 

 tained from the dam when it is des- 

 irable to store water in the reservior. 

 It is proposed to do considerable re- 

 connaissance work in the northern end 

 of the Territory, at the headwaters of 

 San Pedro River and on San Carlos 

 and San Francisco Rivers. 



Mr. Louis C. Hill is the supervising 

 engineer in charge of thework on the 

 Salt River project. 





RECLAIMING THE ARID LANDS OF 



THE NORTHWEST 



BY 



THOMAS COOPER 



Land Commissioner, Northern Pacific Railway. 



O single feature of the develop- 

 ment of the Great Northwest 

 the states of North Dakota, Montana, 

 Washington and Oregon is more sig- 

 nificant of future greatness than the 

 work done during the last decade in 

 bringing the semi-arid land under cul- 

 tivation and in developing methods by 

 which great areas are made immense- 

 ly productive. 



Irrigated lands produce never-fail- 

 ing crops. The land and the water, 

 primary elements in crop production, 

 are known quantities and can be de- 

 pended upon. Adjacent to the princi- 

 pal areas of the Northwest in which 

 irrigation development is now in pro- 

 gress are splendid home markets wait- 

 ing to take all that the land will pro- 

 duce. 



The land to be brought under cultiva- 



tion through the work of the United 

 States Reclamation Service, the or- 

 ganization through which the Federal 

 Government is carrying out the largest 

 scheme of irrigation development and 

 irrigating works yet attempted, will 

 be thrown open to settlement as fast 

 as the water is supplied, under terms 

 which, from the standpoint of the set- 

 tler, will be very reasonable. 



Land irrigated by the United States 

 government will be subject to entry 

 under the Homestead act, as modified 

 by the Reclamation act. The cost of 

 irrigation works and the expense of 

 furnishing water to a given district 

 will be apportioned pro rata to the 

 acreage benefited and the cost per acre, 

 thus obtained, is what the settler pays 

 for the land and the water rights, in 

 ten annual payments without interest.
