My attention baa been attracted to Mr. Adair's article in the April number of your magazine, on the Gareullo and the mischief occasioned by the little "Turk," and it occcurs to me to inquire of yon whether any one in your region, or in the vicinity of Avon, has ever treated the olfactories of the Curcullo to the perfume exhaled from the water of the Sulphur Springs at Avon, by syringing the Plana tree with the water thereof as soon as the fruit sets, and afterwards - and if so with what effect?

Allowing the theory to be correct, that the Curcullo can be kept at bay by nauseous effluvia, is it not worth the trouble of an experiment to see how efficacious it may prove of offering him a few doses of this, in your region, cheap perfume. Perhaps I may have been anticipated by the observation of some of your friends residing at or near Avon, as to the fact whether or not the Plum, and other smooth-skinned fruits, where the atmosphere is partially saturated with the exhalation from the Springs, escape the attacks of the Curcullo.

We possess no information on this subject Will some of our Avon friends look into the matter and let us hear from them ?

The Curculio #1

I notice in your June number, just received, a short letter from Mr. Bacon on the subject of the Curculio, and a proposition to employ sulphureted water, such as that of Avon for syringing the Plum trees; and it may not perhaps be altogether uninteresting to you to know that a series of experiments are being made on this subject by a few amateurs of this city.

Some years ago in a paper published in the Canadian Agriculturist, I endeavored to account for the supposed efficacy of the lime and sulphur wash by the formation of a chemical compound - the sulphide of calcium, its gradual decomposition on exposure to the air, and slow evolution of sulphureted hydrogen, a gas which is well known to be highly destructive to animal life. My experiments on this preservative were quite unsuccessful, and I was equally unfortunate in driving away the "Turk" by means of assafoetida, a substance which you will allow is nearly unsurpassed as to odor.

Last year a lady amateur of this town tried, at the suggestion of a chemical friend, the action of sulphureted hydrogen, as evolved from the proper mixture, and subsequently of a peculiar compound well known to chemists - the hydrosul-phide of ammonium. The trees thus treated were loaded with fruit, those unprotected had none I

This year two or three persons are trying a quantity of the hydrosulphide, and as soon as the fruit is thoroughly out of danger, I will send you the results. In my garden I am trying it on several trees, leaving others unprotected. A few ounce phials are half filled with the liquid hydrosulphide, diluted with about two parts of water; every three or four days I add a little more of the liquid, or as often as its odor begins to diminish. It is scarcely necessary to remark, that the delicious scent of the garden is by no means improved by the process.

It is almost too soon to say any thing with regard to the result of my own experiments, but I may state that on several fine Plum trees, on which last year I had to search for a quarter of an hour in order to find an unbitten Plum, I have now to look almost as long to find a bitten one. On a "Lawrence" the result has not been so favorable, about one-fifth or less being bitten; last year I had none on this tree.

At the end of the season I shall endeavor to obtain the experience of the different amateurs who are now trying the experiment, and should you think it desirable, will forward to you the results.

The substance employed could be made at a very small price, if there should arise any demand for it. At present chemists generally make it for themselves.

Curculio #2

It is stated that Mr. John Brush, of Brooklyn, N. Y., has saved the plums on a number of trees, the present season, by binding bunches of tansy upon the limbs, in several places. The fruit upon the trees thus treated ripened to perfection, while that near by, not thus protected, was entirely destroyed by the insects.

Try it by all means, and everything that " promises well." For ourselves, the only plums saved this season from the arch destroyer have been a few sewed up in millinet!

Curculio #3

Your correspondent Wm, Hopkins, exhibits much judgment in his remarks on the cnrculio. What good will your plum and poultry yards produce, unless all your plum growers in the neighborhood, pursue the same course, as you all agree the insect knows how to use its wings? What good can result from lime, salt or tobacco, when the young insect glories in possessing them? All I can say, is, that in 20 years, I have not lost a crop from the cnrculio, from more than 80 trees, in a brick pavement, round my house. From trees in the garden, I have had a crop for two years only. I see it stated, east, that where a part of the branches extended over a stream of water, no plums were touched by the cnrculio, but where over the ground, all were destroyed. The reason I assign is this. The instinct of the insect, teaches it not to deposit its egg over a pavement, as the young, when it falls to the ground, cannot get thro' the pavement, to obtain winter quarters. The insect is timid, and not fond of congregating where persons are constantly passing, or hogs or poultry constantly under the trees. It is true, the hogs and poultry may destroy all the eggs in your plums, but you can generally depend on the liberality of your neighbors, to give you an abundant supply when your fruit is growing.

Yours truly, N. Long worth. Cincinnati, O.
