THE IKEIGATION AGE. 



As to the power of retaining heat it is interest- 

 ing to note that sandy soils cool more slowly than clay, 

 and clay more slowly than peaty soils, or those rich 

 in vegetable matter. Vegetable mold will cool as much 

 in one hour as a clay in two, or a sandy soil in three 

 hours. That is, after the sun sets the sandy soil will 

 be three hours in cooling; the clay two, and the soil 

 rich in vegetable matter, one hour. It is also inter- 

 esting to note that on those soils which cool the soon- 

 est dew will first begin to be deposited. 



Man possesses very little power over the relations 

 between the soil and heat other than growing plants 

 whose abundance of leaves and luxuriant growth will 

 shade the ground, prevent, or retard evaporation, 

 and enable the soil to maintain a uniform heat, or 

 mixing sand with less heat-retaining soils. These mat- 

 ters are of more importance in kitchen garden culture 



OUR AIM. 



We are striving to reach the seventy and more thou- 

 sands of irrigators in the great west, believing that 

 they will appreciate our efforts and give THE IRRIGA- 

 TION AGE such support as it is entitled to claim. We 

 have always said, and we repeat, that we are honestly 

 laboring for the homeseekers in the arid and semi- 

 arid regions of this country, and have no object in 

 view other than their welfare. Moreover, we purpose 

 to make this paper one for the family one that will 

 be always acceptable. It will be the organ of all irri- 

 gators, and if any one has anything on his mind that 

 will be for the benefit of himself or of his neighbors^ 

 let him write us. and the mere subscription price will

than in the fields; but there are deep valleys among 

 the mountains where the sun rises about 9 a. m. and 

 sets about 3 p. m., and in these, there being so little 

 scope for the sun's rays and the soil being cool for a 

 much longer period than it is warmed by the sun, the 

 power of retaining heat would render one soil more 

 valuable and favorable to plant growth than a soil 

 less retentive.
