Prevention and Piemedies. — Where infestation is known 

 to be present the cocoons should be carefully searched for on 

 all boughs in reach from the ground, or other observable 

 localities, and these should be destroj^ed with the contents, or

 handles would be desirable. I have myself found a form with 

 light handles about five feet long very convenient.

 applications, such as are customarily used for leafage attacks, 

 would be equally serviceable in the case of this infestation.
