examined every twelve days throughout the season, and a careful 

 account kept of the worms or chrysalids found under each ; and 

 where it was a question as to the comparative merits of the differ- 

 ent traps, they were placed on trees of the same variety. The 

 results of these experiments — not to waste space with the detailed 

 array of figures — may be thus summed up : 



No apple-worms were found until the 14th of June; and though 

 many other insects had previously taken advantage of the shelter, 

 not a single plum curculio xoas found. While, therefore, there is no 

 harm in having the bandages on early, in ordinary seasous, little 

 if anything will be lost by waiting till the first of June. Where 

 three of the Wier traps were on the same tree, I obtained more 

 worms than where there was but one ; and where there was but 

 one, there was no difference in favor of position as regards direc- 

 tion or altitude. The lath canvas encircling the tree, secured on 

 an average five times as many worms as any single Wier trap. 

 The rag, paper, and hay bandages allured almost as many, and 

 either kind more than the single Weir trap. 



Time, expense and eflSciency considered, so far as one year's com- 

 parison will warrant conclusions, I place the different materials 

 enumerated in the following order of merit: 



1. Paper bandages. Common straw wrapping-paper, 18x30, 

 can be bought for sixty cents per bundle. Each bundle contains 

 two hundred and forty sheets, and each sheet folded lengthwise 

 thrice upon itself will give ns eight lawyers, between two and three 

 inches wide, and be of sufficient length to encircle most ordinary 

 trees. It is easily drawn around the tree and fastened with a tack, 

 and so cheap that when the time comes to destroy the worms, the 

 bandages containing them may be detached, piled in a htap and 

 burned, and new ones attached in their places. If eight bandages 

 are used to each tree during the season, the cost will be just two 

 cents per tree, and the owner could well afford to treble the num- 

 ber of sheets and keep three on each tree, either together or in 

 diflferent places. 



2. Rags. These have very much the same effect as paper, but 

 are more costly and difficult to get of the requiste length. Where 

 they can be had cheaply, they may be detached from the tree and 

 scalded with their contents. 



3. The Wier trap is perhaps the next most useful ; but both cost 

 and time required to destroy the worms are greater than in the 

 first two methods. 



4. The lath-belt is the very best of all traps, as far as efficiency 

 goes, but is placed fourth on the list, because of the greater cost 

 and trouble of making. On the same kinds of tree (Early Uarvest), 

 and in the same orchard, I have taken with this belt, between 

 June 15th and July Ist, as many as sixty-eight and ninety-nine 

 larvae and pupae, against fourteen and twenty in the single Wier 

 trap. 



5. Hay bands, on account of their inconvenience, I place last. 



The experiments were mostly made in a large and i-ather neg- 

 lected orchard. All these methods are good, and the orchardist 

 will be guided in his choice by individual circumstances."
