252 THE PEACH. 



It is established beyond a doubt that the Yellows is propa- 

 gated by budding or grafting — that the stock, whether peach 

 or almond, is sure to become infected, and is lost — and, that 

 the seeds of diseased trees produce young trees in which the 

 Yellows invariably break out.* Even stones from healthy 

 districts, when grown in infected regions, produce young trees 

 that soon fall a prey to this disease. The same happens also 

 when the peach is budded on the plum or apricot. 



Remedy for the Yelloivs. It is confidently believed that 

 with proper attention and care this very formidable malady 

 may be easily remedied. The process is as follows : 



1. We should exterminate every tree^ both root and branch, 

 that has the Yellows. No other tree should be planted in the 

 same place for several years thereafter, unless a thorough 

 removal of the soil is effected. 



2. Great care should be taken to obtain stones for planting 

 from perfectly healthy trees ; or, buds that are known to be 

 healthy. Nurserymen and farmers in districts liable to the 

 Yellows should use the utmost care to procure from places 

 known to be entirely exempt from the disease. 



3. To use every effort to preserve the trees in a vigorous 

 and healthy state ; and, in doing this we should, from the 

 Urst hearing year^ practice the shortening-in system of 

 pruning, which we have already described. It will certainly 

 secure the trees from over-bearing and all its disastrous con- 

 g'equences, and preserve them in proper vigor, health, and 

 productiveness for many years. In a word, it will certainly 

 and effectually prevent the Yellows where it does not already 

 exist in the tree, and improve the size and quality of the fruit 

 to an extent almost incredible. 



Independent of the Yellows, says a writer in a standard 

 work on pomology, '' The effect of shortening the shoots of 

 the peach is not merely to throw more sap and juice into the 

 fruit, but to add vigor and health to the tree generally, by 



*The yellow variety of the peach are much more liable to this disease than any others. 

 It is well known that they produce the heaviest crops, and are liable to ovrr-liear, which 

 greatly reduces their vigor— and the greatest number of victims are always to be found 

 among the yellow-fleshed peaches.
