I am very much obliged to you for the information you gave me last autumn, as to the winter disposition of my roses; it kept them as nicely as possible,and this summer they bare made me quite famous, and people sometimes come from quite a distance to see them. But what shall I do to my Chroms. tella? It grows and branches out until it looks like - a centipede ; it isn't a pretty comparison I know, and if my rose would behave itself properly, I should not think of it, much less speak of it. In the first place it is sixteen feet high, and every two or three inches along the whole length, there is a branch from two to three feet long ; and it will not blossom - and when it does blossom it is not what it should be. Two years ago it was yellow - a true Chromatella, as I suppose ; last year it would not spend timee to blossom; this spring it had eight blossoms, but they were white, with pink edges and just a faint shade of yellow in the centre. Is there no way to bring them back to their original color? Is this change in consequence of being near other roses? The great thing has nearly killed my poor little white moss rose, by fairly star* ing it out.

I do not like your correspondent J. C. H. (I have just read his article on " birds, insects, and other matters" in the July number.) I am very angry with him. I think that if I had an opportunity I should feel strangely tempted to pull his hair! Probably if he knew it, bis an-swer would be something like that of Napoleon's ambassador to the old lady: " Madam, the Emperor would be very sorry to learn that you have so poor an. opinion of him." Or something like it. But I am angry nevertheless. " Boys do not shoot birds," do they? Then I am laboring under a delusion in thinking that my own pet robins, and bine-birds too, became food for - fishes, once upon a time? There are a few boys in these United States, who do not lire in the city, and who are not such very poor marksmen either, as Iknow to my cost. But I find that writing about it is by no means a soothing process, so I will stop, lest I say something to be sorry for, or ashamed of.

But do tell me what to do for my rose, Mr. Downing, for 1 very much fear it is a hopeless case. Very respectfully yours, A Sobsckibbh at the West. July 15,1862.

Oar " Subscriber at the West" most not lose her patience with her Chromatella rose, and she will hare abundant reason to be satisfied with it next season. At present - as is al-ways the case with this rose, when it has fair play, it is vindicating its nature as a climber, and expending all its energies in growing. Let it grow, and the larger it gets the more superb will be its bloom, when it comes into a flowering condition again - which it will doubtless do next season. We seen it, farther south, covering a trellis 60 feet long, loaded with flowers at the end of every branch. There, it stands the win-ter without care, but in Illinois our correspondent will have to bend it down and cover it so as to protect it from frost and wet in winter. All that need be done with it this season, is to let it grow till the middle of October as freely as it likes. Then commence pinching off the end of every shoot, and repeat this if it starts again. This will force the young wood to ripen well before winter, and next season the plant will doubtless bloom very profusely.

We quite agree with our "Subscriber at the West" in differing from J. C. H. in his opinion regarding the worthlessness of birds as insect destroyers. If J. G. H. will examine the works of any of the entomologists who have taken pains carefully to study the habits of insects, he will find them continually referring to the agency of birds in destroying or preventing the excessive increase of various sorts of insects. We ask, as a specimen, his attention to the follow, ing paragraph, which we quote from Harris Insects, p. 26. "A cautious observer, having found a nest of five young jays, remarked, that each of these birds while yet very young, consumed at least fifteen of these full sized grubs (cockchafers) in a day, and of course would require many more of a smaller size. Say that, on an average of sizes they consumed twenty a piece, these for the five, make one hundred. Each of the parents consume say fifty, so that the pair and family consume two hundred every day.

But as the grub continues in that state four seasons, this single pair, with their family alone, without recognizing their descendants after the first year, would destroy 80,000 grubs. Let us suppose that the half, namely, 40,000 are females, and it is well known that they lay about 200 eggs each; it will appear, that no less than tight millions have been destroyed, or prevented from being hatched by the labors of a single family of Jays. It is by reasoning in this way, that we learn to know of what importance it is to attend to the economy of nature, and to be cautious how we derange it by our shortsighted and futile operations.'1 En.
