RIVERS OF YUMA COUNTY.

In regard to climate, healthfulness, fer 'tility and productiveness of soil, facilities for cultivation, irrigation and abundance of water supply, variety of resources ana cheap transportation by rail and by water, no part of Arizona can surpass Yuma county, which is destined to become one Of richest and most prosperous counties Tn Arizona.
 It lies between 3293 OO' and 3z' 20' north latitude and llS0 2O' and ll40 40> west Longitude. It contains 6, ASS, 32O acres. It iis about as large as the States of Rhode Island, Connecticut and Delaware com lbiSed, or as large as either New Hampshire, Vermont or Massachusetts.
 The western boundary of Yuma County is formed by the Colorado river, which separates Arizona from California. The county is bounded on the north by Williams Ferk and the Santa Maria river, whose waters flow into the Colorado; on the east .bv the counties of Pima, Maricopa and Yavapai, and on the south by Sonora, Mexico. Its county seat is the town Of Yuma.
 The Colorado river drains the entire ter irftery of Arizona, and every drop ot water which falls on its mountains and plains finds it's way to this mighty river. It IS formed by the union of the Green ana Grand rivers, fed by the streams which rise in the Rocky Mountains, and the melt ing snows cause a greater depth Of water in this river m summer than in winter. thus furnishing the most water at the season when it is most required for the purposes of irrigation and agriculture.
 It will be seen that for the entire distance along its western boundary, Yuma County possesses the great advantage of cheap water transportation.
 The Gila river rises in the western part of New Mexico and is fed by numerous streams, among the most prominent oi which are the San Pedro, Agha Fria, Has, rsayampa and Salt rivers. It flows west through Yuma County and empties into the Colorado at the town of Yuma.
 Yuma county, traversed by these great rivers from its northern to its southern' and from'its eastern to its western bound aries, possesses a far greater water supply than any other county in the Territory, and far more than can be found in all Call fernia.
 This water is now being diverted from It; natural channels by means of numerous large irrigating canals, and utilized tor the ;oa=pose of retaining and ifrigating the limmense tracts of lands which lie in this favored country, and which are as fertile as any in the world.
 The Southern Pacific Railroad crosses the Colorado river at the town of Yuma anc runs through the county, following the tarerol course, and at an average distance If about four miles south, of the Glla river rendering all the lands susceptible Of lrrl tcation and cultivation, can find an easy ,outlet in this way and can be transport ted to all the markets and dcenters Of population s:n the East or West.
 Another competing railroad is projected erom San Diego. California. to the to"I of Yuma, aEd thence along the north sla' of the Gila river. Thus Yuma County VII naye exceptional railroad advantages.
