which the insect can be combated practicably and with any suc- 

 cess. It is capable of doing much damage, especially on new 

 and valuable varieties. 



The remedy is simple. As soon as a drooping tip is seen, eithei 

 pull up the shoot or cut it oflf several inches below the girdle and 

 burn it. This method faithfully carried out throughout May, 

 will quickly check the pest. There is no possible chance of get- 

 ting at the insect with a spray. Simply burn all infested shoots 

 in May.
