RIVERS OF YUMA COUNTY.

In regard % climate, healthiulness, fer -sility and productiveness of soil, facilities for cultivation, irrigation and abundance ot water supply, variety Of resources and cheap transportation by rail and by water, no part of Arizona can surpass Yuma eounty, which is destined to become one Of richest and most prosperous counties in Arizona.
 It lies between 32o O0' and 340 20' north .lstitude and ll30 20' and ll40 40' west longitude. It contains 6. ASS, 320 acres. It is about sg large as the States of Rhode Island, Connecticut and Delaware cOm- 'bixed, or as large az either New Hampshire, Vermont or Massachusetts.
 The sestern boundary of Yuma County is formed by the Colorado river, which separates Arizona from California. The county is bounded on the north by Williams Eerk and the Santa Maria river. whose waters flow into the Colorado; on the east by 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 ritery of Arizona, and every drop ot water which falls on ita mountains and plains inds its way to this mighty river. It is formed by the union of the Green snd 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 III 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 Of ,yliich are the San Pedro, Aqua Fria, Has, sayampa 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 it's 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 Cali fernia-
 This water is now being diverted from its natural channels by means of numerous large irrigeting canals, and utilized for the purpose of retaining and irrigating the immense tracts of lands which lie in thls favored country, and which are as fertile as any in the world.
 The Southern Pacific oRailroad crosses the Colorado river at the town of Yuma and runs through the county, following the venerol course, and at an average distance of about four miles south, of the Gila river, rendering all the lands susceptible of irri- ration and cultivation, can 6nd an easy outlet in this way and can be transpOi ted 50 all the markets and centers of population in the East or West.
 Another competing railroad is projected from San Diego. California, to the town ,ofYuma, aEd thence along the north side of the Gila river Thus Yuma County will have exceptional railroad advantages.
 THE CLIMATE OF YUMA.
 The climate of Yuma for nine months of the year has no equal, as we believe, in the world, and during the remaining three months of the year, comprising June. July and August, the heat is not oppressive. Even though the thermometer in mld-sum. syner may aa times rise above l00', and oc- casionally even reach ll00, yet, owing to :the absence of moisture in the air, itis not oppressivc. The atmosphere is pure, light and balmy. When the mercury marks the highest extreme of heat, person does not feel that oppression or debility which IS felt in the Eastern States when the mer' .curv is ranging from e0' to 9O'. The air IS so dry that perspiratron is absorbed as soon as it reaches tse surface of the body, and at no time in the summer does the heat trrsduce any discomfort.
