Mr- Editor; From different sources I hear of the depredations committed upon trees, the past winter, by the mice and rabbits. Thinking the method, whereby some can be yet saved (which will otherwise perish), may be new to some of your subscribers, I give it, claimitig no originality, however, for it is old. The annexed figure may give you a hotter idea of the modus operandi than 1 could detail.

A, A. The trunk of a tree in part, B. The part barked all around, C. A crooked scion, prepared to insert. D. A scion, inserted into the bark below and above the girdled part. E. The bark of the tree.

Many trees of value are girdled all round, and, without something like the foregoing, cannot easily be saved, I this evening finished fixing some of my most valuable trees, three inches in diameter, that have been barked all around for six inches from the surface of the ground upwards; they may be stuck all round the tree, which, when the sap begin a to rise, may be communicated from the root to the trunk, above the girdled part; bank up the earth to as to cover the whole of the scions.

Where the girdle is hut narrowband near the ground,the hanking of earth over it may sometimes save a tree, as there will he buds lent out from the bark above the injury, but it is not always sure.

Trees barked high up by the rabbits, may be treated in like manner, but, in that case, a grafting box must be used to cover the wounds, keep air out, etc. Trees treated thus ought to be staked, so as to prevent rocking about, otherwise the scions wilt not have a chance to grow fast. If you can make anything out of the above, and have nothing better on hand for the occasion, it is at your service; if not, all right, etc.

While on the subject of mice, let me tell those that are breathing out vengeance against the little vixens, that if they will prune their trees in the fail, throw the green brush under the trees, the mice will feed upon them, and let the trees alone, as I observe, invariably, that wherever I left cuttings or limbs under the trees, they wore all peeled off, while the tree, hut one foot off, was untouched* Let horticulturists mark this for the future, S.

[To prevent the ravages of mice another winter, tread the snow firmly round the trees the first time it falls, and keep up the process during the whole winter, after every successive fall. - Ed. ]
