THE IRRIGATION AGE. 



713 



It was for the purpose of utilizing some of this waste 

 that the orchardists of the Pacific coast states and Arizona 

 began the practice of winter irrigation. The precipita- 

 tion usually occurs in winter in the form of rain, and 

 large quantities of creek water are then available. This 

 water is spread over the orchards in January, February, 

 and March, when deciduous trees are dormant. The most 

 favorable conditions for this practice are a mild winter 

 climate; a deep, retentive soil which will hold the greater 

 part of the water applied; deep-rooted trees; and a soil 

 moist from frequent rains. 



The creek water which was applied to some of the 

 prune orchards of the Santa Clara Valley, California, dur- 

 ing the winter of 1904 was measured by the agents of this 

 office with the following results: From February 27 to 

 April 23, 1,241 acres were irrigated under the Statler ditch 

 to an average depth of 1.58 feet. From February 12 to 

 April 23, 2,021 acres were irrigated under the Sorosis and 

 Calkins ditches to an average depth of 1.75 feet. In the 

 majority of cases the orchards which are irrigated in 

 winter in this valley receive no additional supply of mois- 

 ture other than about 16 inches of rain water. 



In the colder parts of the arid region winter irrigation 

 is likewhe being practiced with satisfactory results. The 

 purpose is not only to store water in the soil but to pre- 

 vent the winterkilling of trees. Experience has shown 

 that it is not best to apply much water to orchards during 

 the latter part of the growing season, since it tends to 

 produce immature growth which is easily damaged by 

 frost. In many of the orchards of Montana no water is 

 applied in summer irrigation after August 20. Owing, 

 however, to the prevalence of warm chinook winds, which 

 not only melt the snow in a night, but rob the exposed 

 soil of much of its moisture, one or two irrigations are 

 trequently necessary in midwinter.

The Agricultural Experiment Stations. 



Many inquiries have reached us at times during the past 

 years for information concerning the various experimental 

 stations, and we have concluded to publish regularly hereafter, 

 the following list, which gives the state, the name of the 

 college, also the names 'of proper official at each station with 

 whom to communicate when information is desired. We trust 

 that our readers may derive some benefit from this plan.
