 improved the power canal by consol- 

 idating the banks. The grading work 

 for this canal -was done by Sherer & 

 Co., of Los Angeles, and the tunnel 

 work by John Tuttle, of San Fran- 

 cisco. Water will be diverted from 

 the river to the power canal about a 

 quarter of a mile below the confluence 

 of Final Creek and Salt River. The 

 canal is 19 miles long and its construc- 

 tion has involved the excavation of 

 about 600,000 cubic vards of material 



The cement mill, which has been 

 ready to run since the middle of Feb- 

 ruary, is now in operation. The fuel 

 used in burning cement in the kilns is 

 crude petroleum from the California 

 oil fields. The beginnig of manufac- 

 turing cement was delayed through 

 the fact that only one tank of oil 

 reached the mill during March. That 

 had been two weeks on the road, 

 weighed about 2,500 pounds and 

 required six horses to haul it. The 

 other oil tank got stuck in the mud

Until power can be obtained from 

 the power canal, a temporary steam 

 plant has been built for the purpose of 

 furnishing power to the machine and 

 wood shops and for running the 

 cement mill. It has also run the hoist 

 for the material, which has to be ele- 

 vated 300 feet to the cement mill, and 

 has furnished light and power for

About 400 tons of machinery and 60 

 tons of structural iron have gone into 

 the construction of the cement plant. 

 The ball mills weigh about i _' tons 

 each ; the- tube mills, when ready for 

 grinding, weigh about 20 tons, the 

 crusher 15 tons, and the rotary kilns 

 for murning the cement are 7< > feet 

 long and weigh 40 tone each. 

 Attached to the mill is a well-equipped 

 laboratory under the charge of two
