camp very rapidly during part of the past winter.
 It might be said of the unwelcome rains. however. that they rather i'm proved the power canal by consoli- dating the banks. The grading work for this canal was done by Sherer & Co, of Los Angeles, and the tunnel work by John Futile, of San Francisco. Water will be diverted from the river to the power canal about quarter of a mile below the confluence of Pinal Creek and Salt River. The canal is 19 miles long and it's construction has involved the excavation of about 600,- 900 cubic yards of material and the driving of nearly 5000 feet of tunnel.
 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 ce- ment 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 drilling operations in the tunnels at the dam.
 The cement mill, which has been ready to run since the middle of FeD- ruary, is now in operation. The fuel used in burning cement in the kilns is crude petroleum from the California oil fields The beginning of manufac- turing cement was delayed through the fact that only one tank of oil reached the mill during March. That had been tive weeks on the road. weighed about 2500 pounds and re Quired horses to haul it. The other oil tanks got stuck in the mud be- tween Globe and Roosevelt ana had to be abandoned.
 About 100 tons of machinery and GO tons of structural iron have gone into the construction of the cement plant. The ball mills weigh about 12 tons each; the tube mills, when ready for grinding weigh about 20 tons, the crusher 15 tons, and the rotary kilns for burning the cement are 70 feet long and weigh 40 tons each. At tached to the mill is well-equipped labratory under the charge of two 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 20O,- 900 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 cost S5.3J q barrel delivered at the point wheT C it was used. Bids were later received for furnishing cement at $4.S1 a Dar- rel. It will cost the Government S1.6o a barrel to make the cement on the ground. If the cost of the plant, $l2o.- 900, be added to the cost of the 100000 barrels of cement required, the total cost of the Government cement will still be only S2.20 a barrel. This means a saving of s2.61 a barrel, or a saving of S522, 900 on the entire work. After the dam and canals have been completed, the cement plant will still be capable of further use, and con siderable salvage may doubtless be realized.
 Two new guaging stations were es abolished on Little Colorado River and it's tributaries during March. A party has been surveying a possible power canal on Verde River, the power to be used to supplement that obtained from the dam when it is desirable to store water in the reservoir. It is proposed to do considerable recon naissance work in the northern end of the Territory, at the headwaters of San Pedro River and on San Carlos and San Francisco rivers.
