appear. Lastly, thousands of tlie moths, and thus hundreds of 

 thousands of eggs, can be destroyed by building fires in the or- 

 chards as before recommended. Not only use these preventive 

 means yourself, but urge the same upon all your neighbors. 



The Canker WoR:sr is by many confounded with the tent 

 caterpillar, but is of a different habit, and requires different pre- 

 ventive measures. The female moth of this species is wingless. 

 They begin to come out of the ground early in the spring, and 

 crawling to the nearest tree deposit their eggs upon the branches, 

 and then die. The eggs hatch about May first to fiheenth, and 

 the worm immediately commences its ravages, which are often 

 fearful. Vv'lien they attain their full growth they are about 

 an inch in length, from whence they are often called inch 

 worms. They attain their growth in about four weeks, when 

 they drop or crawl to the ground and descend into it until 

 another season. To prevent these operations is more difficult 

 than with the caterpillar, but an application of melted rubber 

 around the trunk will prevent most of the females from ascend- 

 ing the tree. A band of grafting clay about the trunk and 

 covered with tar will answer the same purpose. The orchard 

 infested with canker worms should be plowed up in the fall, 

 and the pigs and poultry turned into it. Bark Lice are often 

 found on young trees in great quantities; they should be 

 washed off with a strong solution of soapsuds. If found on 

 old trees, the old dead bark shoula be all scraped off and 

 soapsuds scrubbed into every crack and crevice with a brush, 

 as high up as you can reach. 



The Apple Worm is hatched by a small gray- winged moth, 

 which appears in great numbers the first warm evenings in June, 

 and lays its eggs in the blossom end of the fruit, where soon 

 hatches the little grub which eats its way into and spoils the 

 apple, causing it to fall prematurely to the ground. Soon after
