that of the insect, and the principal one is the 

 not stirring of the ground ; I apprehend, that the 

 disease called " yellows" is often thus occasioned. 

 Last year my peach orchard was considerably 

 affected ; and the ground had not been ploughed 

 for three years, and had become quite covered 

 with grass. In the spring of the current year 

 I had it well broken up, and kept clean during 

 the summer; the trees soon assumed a healthy 

 appearance, and furnished a plentiful supply of 

 fine fruit, and the whole orchard is now in the 

 most flourishing condition, and I believe there 

 will be no difficulty in keeping it in that state." 



But my friend Mr. J. Gilliams, has certainly 

 derived great advantage from the use of the 

 cinders of the common anthracite, which is now 

 so generally introduced as a fuel; he opens a 

 small basin around the trunk of the tree, and fills 

 it with the cinders ; he informs me that the trees 

 thus treated, have assumed a more healthy 

 appearance than others, and they are not at all 

 infested by this destructive insect. 



In Mr. Skinner's very useful paper, the 

 American Farmer, (vol. vi. p. 14.) are a few 

 highly important remarks on this subject, by 

 Mr. William Shotwell, of which the following 

 is an extract: "I cleaned a number of trees, and
