62 FIRST ANNUAL REPORT OF 



instances they have been abandoned entirely on account of the injury 

 caused to the trees from the repeated blows given to the trunk. In 

 small orchards it will be found most profitable to drive a spike into 

 the trunk of each tree and to use two sheets stretched on frames, 

 which can both be dragged or carried and placed in position by one 

 man, while a second person gently taps the iron spike with a mallet. 

 To bring the Curculio down, it requires a light, sudden tap which jars, 

 rather than a blow which shakes, and if the frames are each made so 

 as to fold in the middle, it will facilitate disposing of those which fall 

 upon it. 



In conclusion, the intelligent fruit-grower can draw many a lesson 

 from this account of the Curculio — already somewhat lengthy. Thus 

 in planting a new orchard with timber surrounding, the less valuable 

 varieties should be planted on the outside, and as the little rascals 

 congregate on them from the neighboring woods in the early part of 

 the season, they should be fought persistently. It will also pay to 

 thin out all fruit that is known to contain grubs, and that is within 

 easy reach; while wherever it is practicable all rubbisli and under- 

 brush should be burnt during the winter, whereby many, yes very 

 many of them will be destroyed in their winter quarters. As a proof 

 of the value of this measure when it is feasible, I will state that while 

 the peach crop of Southern Illinois was almost an entire failure in 

 1868, Messrs. Knowles & Co., who have 70 acres of peach orchard 1^ 

 miles N. W. of Makanda, shipped over 9000 boxes. Though they had a 

 few hogs in the orchard, there were not enough to do any material 

 good, and they think they owe their crop to the fact of having cleared 

 and burnt 100 acres surrounding the orchard, in the early spring of 

 that year ; for in 1867 the Curculios had been very bad with them. 

 Judge Kimble, who lives 1 miles N. E. of Cobden, also had a good 

 crop free from their marks, which he attributes to having burnt around 

 the orchard in the spring of the year. 



THE CODLING MOTH OR APPLE- WORM— Carpocapsa pomonel- 



la, Linn. 



(Lepiiloptora, Tortricidfe.) 



The Apple-worm, I find to be quite common all over the State, as it 

 is in almost all parts of the civilized world where apples are grown. 

 Dr. Trimble has devoted page after page to the consideration of this 

 little pest, and yet its whole history and the means of preventing its in- 

 sidious work may be given in a very few lines. It was originally a den- 

 izen of the Old World, but was introduced into this country about the 

 beginning of the present century. The following figure represents it 

 in all its states, and gives at a glance its natural history : a represents 

 a section of an apple which has been attacked by the worm, showing
