The Arizona sentinel., 1895-06-22

line of the great canal, the prelim- mary survey of which he completed a few weeks ago and which runs it's entire length through Yuma county, Arizona. MT. Norton has just completed maps and profile of the proposed work and made careful calculation of the amount of earth, loose rock and solid rock to be ex- cavated with an approximate es, innate of the cost of the same.
 The canal heading will be at Hinton's Island, at the lower end of Euraka canyon. The island is a solid rock back bone in the center of the river, 150 feet long, 80 feet wide and rises 20 feet above high water mark, making a splendid natural anchorage or support for a dam.
 Asthe current is very strong and swift between the island and rock bluffs on the Arizona side valuable water power can be secured for manufacturing, lighting and other purposes. The first 2.200 feet will be cut through solid rock, the solidity of the walls insuring the canal against any damage from a sudden rise of the river. From there to the crossing of the Gila the canal will pass through more or less solid and loose rock country, making the construction rather expensive, but taking Into consider ation the security and perm snency of the banks thus afforded, t will eventually prove more of an ad- vantage than otherwise. The water of the canal will be carried across the Gila through several steel pipes and after again empty ing into the canal will continue on down the valley to the Sonora line
 As the ia Is 0. 528 to the mile water can be carried on to the mesas below Yuma and in Sonora, which will be done as the country becomes settled, as it is we'll known that for grapes and several other varieties of fruits, as we'll as for all of the small grains, the mesas skirting the valley of the Colorado, are unsurpassed. The canal will be sixty feet wide in the bottom with a slope uf one to one and wi Il carry water seven feet deep, volume of 50.O00 miners inches or 1000 cubic feet of water per second.
 It is estimated that this amount of water will irrigate 80,O00 acres, or i25 square miles. The canal from head to the Sonora line will be about 54 miles in length and in it's construction it is estimated that 6,2O3,885 cubic yards of material will be moved, 283,251 cubic yards of which will be solid rock. The cost of excavating the main water way approximates close to three quarters of million dollars, while the additional cost of superstruct- ure, buildings, pipe hne, laterals, etc., will be nearly as much more, making the total cost close to one and half million dollars.
 At casual glance this looks like a large sum to expend on an irri- gation scheme, but when it is con- sidered that it will bring under cultivation SO,0O0 acres of semi- tropical lands, susceptible of the highest state of cultivation, where on can be raised all kinds of cit rus and deciduous fruits, as we'll as grains, vegetables and forage, the cost is only 9 mere bagatelle as compared with the great benefits and profits to be de- rived from the outlay. The value of the lands irrigated, now only nominal will reach enormous fig ures when brought under cuitiya- ton, through the agency of the richly silt-laden waters of the Col orado.
 The successful completion of this great undertaking will be a most potent factor in assisting Yuma county to forge to the front and take that place which nature from the first destined her to occupy, as the first county of all the gr"at southwest. in population, wealth and material advancement,
