HOKXICULTURE. 241 



A preliminary temperature survey of the State covering the years 19€1- 

 1911 and based upon the climatological l-ecords of the IT. S. Weather Bureau 

 was also made. Descriptions are given of the thermal stations in Nevada with 

 mean temperature observations during the above period, together with similar 

 data for Utah and Colorado. A biblioigraphy on orchard heating, together with 

 suggestions on tree planting by A. A. Heller, is appended. 



The authors conclude that orchards in Nevada can be protected, even during 

 a season when the temperature falls as low as 22° F. and frosts occur per- 

 sistently, at an expense vai-ying from 73 to 95 cts. per tree. Windbreaks 

 consisting of the Russian oleaster, lopped poplars or willows, and Lombardy 

 poplars are recommended as a material aid in economic and effective orchard 

 heating. The windbreaks are essential to success wherever the wind is strong. 

 From the temperature data already secured it is concluded that many sections 

 in Nevada contain areas that can be adaptetl by orchard heating to the raising 

 of fruit. The Moapa Valley is practically frostless.
