heaters could not be determined, as their efficiency is increased with 

 the area heated. In small blocks a large proportion of the heat is 

 lost which would have been used in heating other trees in the case 

 of large orchards. A difference in temperature of 4 degrees might 

 frequently be sufficient to save the fruit crop. 



VARIETIES. 



Farmers as a rule have not had much experience in fruit growing 

 and are therefore usually at a loss to know what varieties to plant in

their home orchards. Nearly every nurseryman has certain new 

 varieties or novelties that he is exploiting^ and these or others of 

 uncertain value are the ones tree agents too often succeed in persuad- 

 ing the farmers to buy. Generally these novelties are not as good 

 as the old standard varieties, and if the farmer wants to be safe he 

 will select at least all but a few of his trees from the standards. 



Below is given a list of the standard varieties of fruit trees most 

 commonly grown in Nevada or in the mountain plateau regions of 

 Utah, California, Washington, and Oregon. These varieties are 

 known to do well in Nevada or in near-by States having similar cli- 

 matic conditions and are suggested for planting in Nevada.
