 Lowest temperature. ....... 22.5
 Average annual temperature. 722
 8. How does the heat affect one? A temperature of 90 degrees in the east ern states is far more prostrating and dangerous than the highest tempera- ture experienced in the Salt River val ley.
 g. What is the cause of the differ eDce? The absence of humidity in the atmosphere.
 10. What is the average rain fall? Six and thirty-seven one-hundredth inches, confined principally to the win ter months,
 II. Does it rain continually during the winter? Only day or two at a time, with intervals of weeks of cloud less weather.
 l2. Are the storms violent? Thur der and lightning are very rare. Cy- clones and wind-storms are unknown.
 13. Are earthquakes ever experi- eneed? Slight shocks have been known, but not as frequently as in the Missis- sippi valley.
 IA. How are lung and throat diseases affected by the climate? Most favor ably tbis valley IS a natural sanitarium. The worst cases, both from the east and west ,come here with the most beneficial results, many of them being perman- ently cured. The climatic desideratum in pulmonary diseases is a mild and dry climate. Southern California has mild climate, but it is not dry. Colo rado has a dry climate, but it is not mild. The Salt River valley has eli mate at once mild and dry. Eminent specialists now recommend the Salt River valley in pulmonary diseases
 b. Do malarial or epidemic diseases prevail? Less than in any other part of the United States. The dryness of the atmosphere is uniavorable to the trans mission of disease germs.
 IS. Are there any poisonous reptiles Yes. in the adjacent mountains, but ir- rigaiion drives them away from the cultivated lands.
 F. To what productions is the val. ley adapted? To all those of all the eastern and northern states, besides many of those of tropical countries.
 OTduSe Juuu, tullOT UT Ilt ICdltle Farmer, after visit to the Salt River valley, says of its soil, editorially:
 ''Most of these valley soils are the &C., eumulated washings from the surround ing hills, made up of the fine particles that have been, during countless cen luries, disintegrated by frost, or the chemical action of the atmosphere. The water he (the farmer) uses is also charged with new fertility, thus pro- duced annually and gathered from the sides of the mountains scores and hun dreds of miles away, SO that every flow ing of the land benefits it This is no theoric idea. We have seen thou sands of acres here growing crops that rival in luxriance those found in the famed valley of the Nile, which derives it's vivifying liquid, bearing fertlizing elements, from the far of lands in upper Egypt and beyond. This valley of the Salt derives it's luxuriousness from the mountain regions of interior arid Arizona"
 The special committee of the United States senate, report 92S, part l, May s, 1890, page 60, says: "Within our border there cannot be found soil go uniformly fertile and so capable of varied production, under irrigation, as that of the Gila, Salt and Santa Cruz rivers, in southern and central Arizona. Analysis of this soil shows it's fertile qualities to be superior to that of the Nile earth"
 IS Is the soil durable? As nearly mexhaustible as any known soil. The Maricopa Indiaus, a remnant of a semi- civilized tribe, have raised wheat upon sone of these lands continually since the advent of the early mission in the seventeenth century.
 l9. Do all soils require irrigation? Yes; the rain fall being insufficient to produce any crop without irrigation.
 20. How is water applied for irriga- tion2 For grain and alfalfa, water is applied by aooding the entrire surface of the land between borders, usually 50 tset apart. For fruit, it is run in fur rows near the trees or vines.
