the course of the year. Yet different degrees of virulence, 

 perhaps depending on the stage of the disease, are ob- 

 servable. 



There can be no doubt that on a sickly tree, the pit or 

 kernel is as much affected as the pulp that surrounds it ; 

 and therefore *<uch stones ought never to be planted in a 

 nursery. A peach tree not attacked by worms, and free 

 from this malady, ought to live at least fifty or a hundred 

 years ; and we believe no reason whatever, except the 

 two just mentioned, can be assigned for their early decay. 

 If the worm is not at the root therefore, when the tree is 

 sickly, we may conclude it has the yellows ; and that 

 this disease, if the pit was tainted, has 



" Grown with its growth, and strengthened with its strength." 



Some varieties of the peach and nectarine, are subject 

 to a white mildew, which appears on the new shoots about 

 midsummer, checking their growth, but not attended with 

 any other ill effects. It seems analogous to the mildew 

 on the grape and gooseberry ; and may be cured (it is 

 said) by the application of sulphur water. A better course, 

 however, for culturists in general, would be to stimulate 

 the tree, to make a handsome growth in the early part of 

 the season, and to take no further care. 



This disease appears to be exclusively confined to 

 Lindley's FIRST CLASS of peaches and nectarines, " whose 

 leaves are deeply and doubly serrated, having no glands." 

 Some varieties of this class, however, suffer very little ; 

 while others, such as the early Anne, are much impeded 

 in their growth. 



The peach is justly considered the most delicious fruit 

 of the temperate zone ; and yet it is scarcely known in a 

 large proportion of the State of New-York, which we have 

 much reason to believe would admit of its successful cul- 

 ture. Not only in the high lands between the Cayuga
