An Insect Show

Paris is also to have an "Insect Show" this month at the Luxembourg. The exhibition will contain noxious and useful insectivora, will show the productions of the latter, and specimens of the ravages caused by the former. Among the " usefuls" is a little black fly, myriads of which appeared a few months ago to the great annoyance of the citizen. It would seem that this fly fed upon those infinitesimal insects that infest wall fruit, as well as those which do such injury to corn.

Insects In Flower Pots

A correspondent of the Ohio Farmer tried salt and lime-water successively on carnations and roses in pots. The salt injured the plants, and the lime-water improved the size and numbers of the worms. Next hot water was turned into the saucers of the pots, and warm wood-ashes spread over the surface of the earth and dug in with a hair-pin. The insects were driven away, and the potash was good for the plants. Too large a quantity would, of course, do harm, and consequently caution must be exercised.

Insects In Hot-House

E.B. By no means veture to syringe the plants with the liquid recommended to you. We never heard of the one you name; but we well remember seeing a house of fine plants,, some years ago, burnt up by being syringed with a liquid, which the unfortunate gardener had been recommended by "a friend;" and which we found, on rxamina-tion, to be a weak mixture of muriatic acid and water.

Insects In The Ground

Peter Wall. . If you will take the trouble to throw up the soil into ridges under your plum and apple trees - now - before winter - extending the operation as far as the roots go, you will, by the help of Jack Frost, destroy a large part of the curculiosand other insects that have taken lodgings there for the winter.

Insects On The Roots Of Apple Trees

(J. G. R. R., Lovettsville, Virginia.)

The insec' you describe is the Wooly Aphis - a troublesome pest either on roots or branches, but worse when on the roots. We cannot suggest any effectual remedy. The course we would advise would be to get your nursery trees out of the soil they are in as soon as possible, and plant in new ground. We have rarely seen roots affected in good fertile soil and under good cultivation, and if affected at all, not so seriously as to injure the trees.

Insects On The Vine

Dr. Bute, (Nazareth, Pa.) The gray insect you describe is the vine-hopper. Provide yourself with one of Brown's Patent Fumigators, (to be had at Bu-ist's, Seedsman, Philadelphia,) and pass a stream of tobacco smoke under the foliage of every vine in your vinery - afterwards filling the house with smoke, and shutting it up all night. If the day is damp, the application will be more effectual; two or three operations of this kind will rid you of this pest. The cause of the rot on the hardy vines is not fully known. It is possibly a fungus - the seeds of which float in the air. In a vineyard of an acre which we have, we have found that carefully picking out all the diseased berries, as fast as the rot makes its appearance, entirely puts a stop to it here, but it might not where it is very prevalent.
