Pruning Young Trees 83 



of folly to plant a tree that has a trace of this disease, 

 for not only is the tree almost sure to die before it comes 

 into full bearing, but the infection may be spread by the 

 cultivator or in the irrigation water to all parts of the 

 orchard. 



A statement previously published by the writers, on 

 the subject of inspection, will bear repetition here: "All 

 possible assistance should be given the county inspectors 

 in their inspection of nursery stock. In counties where 

 many trees are being planted, sufficient assistance should 

 be provided, so that there will be no possibility of any 

 shipments being overlooked. And finally, some means 

 should be devised whereby the importance of inspection 

 can be impressed on the growers, since, in some instances, 

 they antagonize the inspectors and hinder their work. 

 It is no doubt true that the inspection of nursery stock 

 alone, if well done, pays many times over for all the ex- 

 pense incurred,. even in those counties which expend the 

 most money in orchard inspection." m 



But in those localities where several- hundred thousand 

 trees are planted each spring, the inspectors are so rushed 

 with their work that the most careful men are liable to 

 overlook an occasional infected tree; therefore no grower 

 can afford to be unfamiliar with these common pests. 

 Each tree should be reinspected as it is planted, and to 

 make the work thorough the roots should be dipped in 

 water so as to remove any dirt that might conceal small 

 galls or a few aphids. 



In this discussion it is presumed that the planting is 

 done in the spring, as this is nearly the universal practice 

 in the arid region.
