give US eight layers, between two and three inches wide, and be of suffi- 

 cient 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 heap 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 

 number of sheets, and keep three on each tree, either together or in dif- 

 erent places. 



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

 more costly and difficult to get of the requisite length. Where they 

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

 their contents. 



"3. The Wier trap, used as recommended last year, 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 it is placed Iburth on the list, because of the greater cost and 

 trouble of making. On the same kinds of tree, (Early Harvest), 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 larvaj and pupas, against 

 fourteen and twenty in the single Wier trap. 



'•5. — Hay-bands, on account of their greater inconvenience, I place 

 last. 



"The experiments were mostly made in a large and rather neglected 

 orchard, belonging to Mrs. Spencer Smith. 



"All these methods are good, and the orchardist will be guided in 

 his choice by individual circumstances." 



I should state here, by way of parenthesis, that all these bandages 

 are most effectual on young and smooth trees ; because, on older ones, 

 where the bark is rough, a great many worms spin up before they leave 

 the tree, and before reaching the bandages, and others spin up below the 

 bandages, hence the importance of scraping. We see here again how 

 perfectly absurd is the claim that all the worms will be attracted to a 

 single one of the Wier traps. They will be attracted to the most cosy 

 place of shelter, whether tliat be afforded by the bark of the tree, by the 

 Wier trap, or by any other trap. 



We can also do much by destroying the worms before they leave the 

 fruit. It has generally been recommended to pick up all the apples, or 

 cause them to be devoured by hogs or sheep, but many varieties of the 

 apple trees do not drop their fruit until after this worm has issued. Now 

 here is a problem for our Agricultural College students to work at. The 

 absence of the worm is generally known by a mass of frass on the outside 

 of the apple. Now, it would be futile to go to a great deal of expense, 

 when the worm had left before the fruit fell from the tree. 



With regard to pears, I have been informed by Parker Earle that the 

 worm invariably leaves before the fruit falls from the tree.
