s * Among the many experiments that have been made for deftroying canker- - 
worms, tarring round the body of the trees feems to have been the moft effectual :.- 
but if the tar be applied on the bark, it will injure the trees, efpecially if they are 
young, nearly as much asthe worms. This injury, however, may be entirely pre- 
vented, and the worms more effectually deftroyed, by putting, next the bark, a 
clay morter well mixed with hair or chopped ftraw, about an inch thick ; upon the 
morter a flrip of canvafs or birch bark’: then take a large rope of fwingled tow, 
twifted by hand, and make two or three turns round the tree, below and clofe to 
the canvas, drawing i it tight upon the moift morter to prevent the tar from running.
