ial; 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. A strong de- 

 coction of tobacco will probably produce the desired 

 effect, and tanner's bark put round the tree, it is said, 

 will have a salutary tendency as a preventive.

LICE, INFESTING YOUNG ORCHARDS, IN THE D1STICT OF 

 MAINE MODE OF DESTROYING THEM. 



"This insect, called /ice, is in form like half a ker- 

 nel 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 eggs each, in form 

 like a snake's egg ; which, in a common season, begin 

 to hatch about the 25th of May, and finish about the 

 10th of June. These nits produce a white animal- 

 cule, resembling a louse, so small they are hardly per- 

 ceptible by the naked eye ; which, immediately after 

 they are hatched, open the passage at the end of the 

 blister, and crawl out on the bark of the tree ; and 

 there remain, with but little motion about ten days ; 

 when they stick themselves fast to the bark of the 

 tree, and die. From this little carcass arises a small 

 speck of blue mou/t?, which is most plain to be seen
