2l6 THE NEW HORTICULTURE. 



lows " will ever be brought under control, and stamped out. If it is 

 not, the industry is doomed for orchards are being destroyed this 

 year by its ravages as never before ; and the yield, instead of being 

 9,000,000 baskets, will not be 50 per cent, of it. L. M., Kent Co.,, 

 Del.) July 24, 1896. 



Here we find the " yellows" and the "June drop " put- 

 ting in their work on the long-rooted and cultivated trees. 

 But did anybody ever hear of "yellows" or the "June drop" 

 bothering seedling peach trees around the house, in the 

 chicken yard, in the fence corners, or any place where the 

 plow could not reach them? In fact, do not even the cur- 

 culio give such trees the go-by? As to "yellows," deep 

 preparation of the ground, making a boggy root-bed, surface- 

 rooted trees, continual yearly or even more frequent cutting 

 of the roots, winter or early spring pruning, fertilizing and 

 plowing, resulting in a premature movement of the sap and 

 subsequent freezing, will easily account for that disease. 

 But it will disappear as soon as growers treat their trees 

 rationally, just as pear and apple blight will. I have proved 

 that blight is not contagious, and that healthy trees cannot 

 be inoculated with it, and have no doubt that it will not only 

 be equally impossible to communicate "yellows" that way to 

 a close root-pruned peach tree in sod or firm ground, but that 

 young trees already affected, if thus set and treated, and 

 top-dressed freely with potash, will recover at once. Those, 

 and doubtless all bacterial tree diseases, are the effect of 

 wrong treatment, resulting in favorable conditions for their 

 development, as shown in the chapters on blight. 



THE END.
