RECLAMATION ENTERPRISE

in the land office. This particular scrip was San Francisco forest re- serve scrip. approved and abstracted, about which there could be no ques- ton, and is valued highly. Above the fork in the canal. or the head of the lateral 4S0 acres have been filed upon. that being all that water could be supplied to at the present time.
 The canal is to be taken out through gates on the upper side of rocky point through which the canal is to be tunneled about fifty feet. which it is believed will furnish an imperishable heading. The water will be taken out three feet below the river grade enabling the use of very low dam With a dam only one foot above the river grade. the canal should draw four feet of water. The sand coming in with the water is to be discharged through sand gates a mile below the head. The velocity of the water from the head to the sand gate will be four feet per second so it is expected that normally the canal will clean itself. The material be- tween the head and the sand gate is of the nature of cemented boulders which will withstand the erosion of the erosion of the water at the stat ed velocity.
 The dam as at present projected will be of sheet piling, though there is to be further testing of the river bed before construction. It will be 170O feet long, with rock abutments at both ends. Though there is yet much in detail to be worked out con corning the dam. the building of a weir only foot or so above the grade of the stream ought not to be em- the water at the stated velocity.
 In respect of water supply few peo- pie are sufficiently familiar with that immediate section to appreciate it's magnitude or permanence. It is known that the Agua Fria is dry most of the year where the railroad crosses it. Nevertheless during the dryest weather this year there was a constant head of from 1000 to 5000 inches at the proposed point of diver sion and as high as 15.00O to 2O.000 inches have been known to flow by that point and all sink or dry up be- fore it reached the railroad crossing At no time so far as can be learned has there been less than 200 to 300 inches of water in the river at the diversion point and since July '. this year. there has been a constant flow large enough tO irrigate all the land proposed to be watered by the Mari nette canal
 But that is not to be the only de- pendence. though it may prove suf- ficient. The gravity system is to be reinforced by a pumpisg plant to be used when needed. to be located near the head where the ground water is never more than five or six feet be- low the surface. This plant will have a capacity of 5000 inches As now planned the power will be furnished by a Nix Frost oil gas producer. general | ing a fixed gas from crude oil With | this device it is guaranteed that crude oil costing S1.70 per barrel will | furnish power at not to exceed one half l cent per horsepower hour.
 The carrying capacity of the canal is to be one and quarter inches con- tinuous flow to each acre of land to | be irrigated so that any time there is flood water during the short sea- son all the farmers can draw at once l Each can have full head all the time and there need be no such thing as rotation in the use of water Ev- cry water user will have an equal show at all the water. The upper three miles of the ditch to the point where it reaches the mesa will be twelve feet wide on the bottom and carry four fee; of water. ihe capacity of the canal being 12.5OO inches From this point the ditch will be twenty feet wide on the bottom and carry three feet of water, the capacity being the same Further down the canal there will be some reduction m size, proportioned to the acreage be- low, so the equitable distribution of water to each acre will not be dis turbed
 One and half miles of the canal Is now built and work will begin on the
