Liquid Grafting Wax. 



By U. S. Department of Agriculture. 



The following Liquid Wax is one of the best in use. It is ready at all 

 times of the year to cover the wounds on trees and it is very serviceable in 

 grafting. Applied with a varnish brush, the work is quickly and thoroughly 

 done. 



Melt one pound of common resin over a gentle fire, let it cool a little, then 

 stir into it a tablespoonf ul of spirits of turpentine and seven ounces of ninety-five 

 per cent, alcohol. If the alcohol cools the mass very rapidly it may be neces- 

 sary to put it on the fire once more, stirring constantly. The utmost care must 

 be used to prevent the alcohol from igniting. To avoid danger, remove the 

 vessel from the fire when the lumps that have formed begin to melt. This 

 must be repeated until the whole mass is converted into a homogeneous liquid 

 like thick syrup.
