70 THE DIFFEKENT KINDS OF FRUITS. 



The Baek Lotjse — is a little brown insect, which appears 

 sometimes in great numbers on the bark of the tree and branches, 

 and lives upon the sap. 



They may be destroyed by a decoction of tobaceo-juice and soap- 

 suds, applied by dipping or sprinkling with a syringe. They may 

 be removed from the body and large limbs by scraping. A mixture 

 of lime, soap, and water is also a good remedy. 



Elliott says : " A good wash for all insects is made of-— say live 

 gallons of weak ley, one pound powdered sulphur, and four ounces 

 soot, or lampblack, thoroughly mixed." 



A solution of aloes is good to protect trees .from vermin — so says 

 Raspail. 



The CATERPiLLAE.^-In some seasons these pests have been very 

 destructive to the apple-tree — so much so as to almost destroy 

 whole orchards. Their eggs are usually deposited in the fork of a 

 limb, or near the ends of the branches, in clusters, where they re- 

 main all winter, and hatch early in the spring. At first they are 

 not larger in circumference than a pin, but continue growing till 

 they reach the size of a small pipe-stem, and two inches in length 

 — living meanwhile upon the foliage, which by the middle of sum- 

 mer will be entirely stripped from the tree. 



To destroy them, cut away and burn the small branches which 

 hold them during the winter, or before they begin to crawl in the 

 spring ; or if this has been neglected, brush them oif witli a swab 

 saturated with soap-suds, or lime-water, or spirits of ammonia. A 

 brush made of rough tow, grass, straw, or old woolen rags, and 

 attached to the end of a pole, and turned a few times in their nests, 

 will remove them. If a few escape and migrate to other branches 

 or other trees, and build new homes, they must be treated in the 

 same manner. The swabs should be burned after being used. 



The Blight. — This is a disease for which no satisfactory cause 

 seems yet to have been discovered. It attacks generally the ends 

 of the branches all over the tree alike. 



As no cause has been discovered, no certain remedy has been 

 proposed* Recourse must be had to the knife. Cut away all the 

 aifected brandies, as low as the disease has appeared, and burn or 

 otherwise destroy them. Continue the process, if necessary, until
