Yellow Pine-.- In controlling infestations in yellow pine, 

 trees over 12 or 14 inches in diameter should be peeled from 

 the butt to the lower limbs ^r .further, if the brush from the 

 tree is not sufficient to form a compact pile over the upper 

 unpeeled part of the trunk. The limbs must be cut small enou ] 

 to form this compact pile; the bark resulting from the peel- 

 ing raked up close to the peeled trunk; and the whole burned * 

 The portion of the trunk on the ground will then have the 

 bark adhering to the under part of the log burned off and the 

 bark of the top and limbs will be destroyed. The stumps must 

 be cut low, not above 18". They must be peeled to the ground 

 and the bark burned around the a tump. By employing this me- 

 thod all beetles dropping on the ground will be destroyed. 

 The main object is to destroy all the bark as it contains the 

 larvae and beetles doing the damage. 



Trees under 12 or 14 inches in diameter may be 

 bucked up in a pile and burned without peeling. The stumps, 

 hoy/ever, should always be peeled on all trees. Tops should 

 be "bucked back" as far as the trunk can be conveniently 

 handled, thus lessening the fire area. Burning is the only 

 known method for destroying insects infesting yellow pines.
