With this design, says Kenrick, the bark 

 around the circumference of the trunk is 

 scraped smooth, and the crevices in it where 

 the application is to be made are filled with 

 clay or mortar. Over this a strip of canvass, 

 three or four inches wide, is bound around the 

 tree, the lower band consisting of a large tow 

 cord, to prevent the running down of the tar 

 and its consequent injurious effect on the tree. 

 On this strip the tar is laid with a brush. 

 The tarring ought to be applied, every after- 

 noon toward sunset when the weather is 

 moderate and the ground unfrozen, from the 

 first hard frosts in October till the latter part 

 of May. A small portion of soft grease may 

 be mixed with the tar to preserve it from dry- 

 ing, and in this way it will answer to visit the 

 trees every other day. Some farmers apply 

 the tar directly to large trees without the 

 canvass, and we have not seen any injury 

 resulting from the practice. Tarring two 

 years in succession in the months of March 

 and April has entirely rid orchards of this 

 pest. 



Downing says, old India Rubber, melted in 

 an iron vessel over a very hot fire, forms a 

 very adhesive fluid, which is not effected by
