develop on their own roots. Unlike most other 

 trees, the chestnut should not be grafted until just 

 before the bark begins to slip in the spring. If 

 grafted much earlier it is necessary to protect the 

 grafts by tying a paper sack over them until they 

 start growth to prevent evaporation; but in every 

 case it is better to wait till shortly before the bark 

 begins to slip. This is unlike the cherry, which 

 must be grafted very early or success is extremely 

 doubtful. 



When grafting is performed after the bark 

 begins to slip, it is necessary to tie down the bark 

 against the graft with a string to keep it in place, 

 otherwise it rolls away from the graft and union 

 does not take place. If grafting is done at the right 

 time and with reasonable care, it is usually 

 successful. 



In the main, very little attention has been paid 

 to the chestnut by cultivators of nuts. Until very 

 recently, such chestnuts as have appeared in the 

 market have been gathered from wild trees, or, 

 imported from Europe. Recently, however, the 

 possibility of cultivating the chestnut has gained 

 a good deal of attention and in a certain number 

 of cases orchards have been started. I have intro-

 one of them known as the Hale, another as the 

 Coe, and the third as the McFarland, and these
