Mr. Editor:- Having read an article in your February number touching the Rose-slug, I am induced to communicate my own experience in exterminating the so-called pest.

I have already made some statements to this effect one year ago, at a meeting of the N. Y. Farmers' Club; and as the season is approaching when such information would be acceptable, I would, if you consider it worth a place in the columns of the Horticulturist, give a more detailed account of my practice. It is this: I obtain from the road a quantity of well-sifted, dry dust. I then procure some soot from the bituminous-coal chimneys, and mix as much of it with the dust as will make a dark-colored compound. I then have a tin box made, in shape and size of a quart measure, with a lid or top to fit, perforated with small holes, similar to an old-fashioned pepper-box. I therein place this fine, dry dust; and early in the morning, while the dew is on the leaves, give them a thorough dredging. This I commence to do when the slug first makes its appearance, and so continue, at intervals, until the rose-buds are about to expand. And also after rains I find it necessary to repeat, as the former application is liable to be washed off the leaves, which encourages them to renew the attack. By a timely commencement of the above process, I will have nearly exterminated the pest from the bushes when they are in fall flower.

By this process I have secured a second and third bloom on my monthly Rose-bushes, which were perfect.

Now, sir, I will give you my reason for using the soot with the road-dust. It is, that the dust in itself is of an unsightly grey color, which, to my eye, is objectionable. By mixing the soot with the dust, we preserve some harmony of color with the foliage. I have used dry, air-slaked lime alone, but what does it look like in combination with roses? Scotch snuff, used in the same way, is good, but rather expensive; furthermore, it does not dissolve readily with the moisture on the leaves, as does the road-dust, thereby rendering it a sort of pasty substance, adhering to the leaves for a longer time. The principle of my theory is, to adopt something of a nature that will attach to the smooth, waxy texture of the leaves, and remain, for the time being, to prevent the close adhesion and comfort of the slug. I do not pretend to say that we kill the slug by this process; but he will "vanish to parts unknown".

The "skip-jack," which is so destructive to the Melon, Turnip, Radish, etc., when they have formed their first leaves, can be exterminated in this way, by applying it at intervals. If this insect can be kept from its desired food for two hours, it will die of hunger. Another brood will probably make its appearance; repeat, until the plant is out of its reach, which will be very soon if the first leaves are cared for. In conclusion, I would say to those who do not consider a little labor and attention a hardship, they will be rewarded with success, as I have been. Geo. II. Hite, Artist.

Morrisania, March 15th, 1861.

[We think the "slug" is in a fair way of "catching it." Mr. Hite, being an artist, applies his remedy with an artist's eye. The idea is not a bad one. We go in for "harmony " in all things. we hope the remedies we publish will be fairly tried, and the results sent to us, that we may know which is the best. The slug will find it difficult to get over all this dusting. - Ed].
