ing any old cloth in the crotch of the trees, from the time they begin 

 to leave the apple till the time the fruit is gathered. I think at present 

 the best remedy would be this : In the fall, when the insect has 

 crept into the cloth for winter quarters, take the cloth from the trees 

 and put it into an oven hot enough to destroy them." Other orchard- 

 ists soon recorded similar operations, and finally, as a natural out- 

 growth of Burrelle's recommendation, 

 Dr. Trimble, after a series of experiments 

 with various ''bands" in 1864, devised 

 his famous " hay-rope band." A reduced 

 copy of Dr. Trimble's picture of his hay- 

 rope band in operation is shown in figure 

 144. In forming an ideal place for the 

 apple-worms in or under which to spin 

 their cocoons this hay-rope band is equal 

 to anything yet devised. 



This "banding system" thus thorough- 

 i ly inaugurated by Dr. Trimble soon be- 

 came the principal and most successful 

 method of warfare against this pest. It 

 was largely practiced during the decade 

 between 1870 and 1880 in many parts of

noticeable improvement in the apples 

 from that state. Extensive experiments have been made since 1869 

 with bands of various kinds by Riley, LeBaron, Cook, Beal, Chapin, 

 Wickson, Popenoe, Washburn and Card ; and within the past 

 three or four years the banding system has received considerable 

 attention in Germany by Schilling. These experimenters dififered 

 in their conclusions as to what was the best band to use. Among 

 those found the most practical and successful may be mentioned com- 

 mon straw wrapping paper, 18x30, folded lengthwise thrice upon 

 itself ; rags of any kind ; a very effective but rather expensive one was 

 formed by lining one side of an old piece of sacking, four inches wide, 

 with strips of lath; strips of old carpet; woolen cloths; old grain 

 sacks cut into strips ; felt paper sold for carpet lining; and strips of 

 heavy express paper cut on a slight curvature and folded together
