plied with a brush to the body of the tree and a syringe 

 for sprinkling over the leaves and branches. A strong solu- 

 tion of whale oil soap is an excellent insecticide and may 

 be used liberally without danger, and with excellent effects 

 both as an insect destroyer, and a solvent of scurf, moss 

 and smut or mould, which often attach themselves to the 

 leaves and bark of the trees. The application of the soapy 

 solution should be repeated every three or four weeks or 

 until every vestige of scale or other disease is removed. 

 The soapy application has a very beneficial effect, even if 

 no scale are present, by removing old bark, cleaning the 

 surface and allowing the functions of the tree fair play. 



Should the scale insects prove obstinate and refuse to 

 yield to the milder remedies, stronger preparations may be 

 applied. A favorite preparation of our own for obstinate 

 cases, and for washing the trunk and braches of older trees, 

 is composed of the following ingredients : Take ten 

 pounds of carbonate of soda (sal soda) and five pounds of 

 any good hard soap. Dissolve the soap in a small quan- 

 tity of boiling water, and put it into a forty gallon cask, 

 (a lard barrel is the best) add the soda, broken into small 

 lumps, then fill up the cask with soft water and stir the 

 mixture till all is dissolved and thoroughly mixed, when it 

 is ready for use, and always on hand. Apply to the trunk 

 and branches of the tree with a brush (we use a common 

 long handled tar brush) give the trunk and branches a 

 thorough scrubbing, then shower the tops, leaves and small 

 branches by means of a rose nibbed syringe. 



This treatment applied twice a year, spring and fall, 

 will keep the trees free from scale, cause the leaves to look 

 a dark green, and produce a clean, healthy appearance 

 generally.
