of from one to four inches ; and in about eighteen 

 days they again ascend from the earth, in the form 

 of flies, and these again deposit their eggs in the 

 leaf; so that they produce two hatchings in a year. 



It is happy for the fruit planter, that a simple 

 method is discovered, by which these destructive in- 

 sects may be effectually destroyed. This is done 

 by means of lime sprinkled over the leaves in the 

 form of powder. For this purpose, a wooden box, 

 of convenient size, having its bottom perforated 

 with numerous small holes, is to be filled with 

 lime. This being mounted on a pole, by shaking 

 over the tree, distributes the lime among the leaves, 

 and the slugs are immediately destroyed. The la- 

 bour is very trivial ; a man may cover a large tree 

 in three or four minutes ; and the desired effect is 

 certain. Fine earth shaken through a basket or 

 perforated box, will answer equally well. 



Another remedy, it is said, will prove equally ef- 

 fectual. It is a strong infusion of tar, made by pour- 

 ing water on tar, and suffering it to stand two or 

 three days, when it becomes strongly impregnated. 

 This, if sprinkled over the leaves by means of an 

 engine, will kill these vermin instantaneously. Tan- 

 ners bark put round fruit trees, will destroy the 

 slug worm.

 MAINE-MODE OF DESTROYING THEM. 



" This insect, called lice, is in form like half a 

 kernel of rye, (but not more than one twentieth 

 part so large,) with the flat side sticking to the 

 smooth bark of the tree. They resemble blisters ; 

 and are near the colour of the bark of the tree. 

 These blisters contain from ten to thirty nits or
