We believe we have already given our opinion that the Osage Orange will make a good hedge no farther north than the peach ripens well. But we have no doubt it will answer at Buffalo. It is found by experience, that as soon as the hedge is sheared, and the growth becomes short and well matured, it is far hardier than when the plants are young. Ed.

Remarks #1

A highly interesting communication. Dr. Schleiden, in some of his works, reasons so poorly that we have little faith in him. Experiments, which may be repeated by any one, prove the passage of the fluids downward, after having risen to the leaves, and been exposed to a distinct process there. The assimilation or digestion is however not completed in the leaf, but depends for that final individuality of character which causes it to make plum or pear tree wood, upon the bark which immediately overlays such wood - for the downward current usually passes through the bark, and is thence distributed horizontally through the medullary rays into the interior of the stem. Hence, whatever the bark is which covers any part of the stem of a tree, such will be the kind of wood deposited beneath that bark - no matter whether the leaves above that bark be pear or quince.

This is not only proved by the familiar fact, that the barks above and below the graft, always maintain their original line of distinction, but more clearly by the experiment made by phiysiologists of grafting rings of the bark of various allied species, as the pear, quince and apple, upon different parts of the same trunk. After growing several years it was found that the pear bark had deposited pear wood - the quince bark, quince wood, and so of the others. There were no leaves to each ring of bark, and the experiment clearly proved that the action of the wood depends on the bark which overlays it, and gives its final character to the downward currant of fluid nutriment just as it undergoes its last change into solid matter.

Remarks #2

Both rockwork and artificial ponds are, in our estimation, dangerous features in ornamental gardens, for any one to meddle with who has not a great deal of taste, or a lively feeling of natural beauty and fitness. We quite agree with our correspondent, that they should occupy secluded spots in the grounds, and that they are never so successful as when they may be wholly mistaken for nature's own work. A little round pond, like a soup basin, set in an open, smooth lawn, and a pile of rocks heaped up upon a formal mound, as we have sometimes seen them, in the midst of high artificial flower garden scenery, are equally offensive to good sense and good taste. Nature puts her small pools of water, and her ledge of rocks filled with mosses and ferns, in the depths of some secluded dell, or under the shelter of some dark leafy bank of verdure.

Touching the rock garden at Chatsworth, we must differ from our correspondent. That rock garden has, to our mind, but one defect, viz: that you enter it from a highly dressed pletely harmonised it with the wild scenery of the high hills of Derbyshire, which rise behind it, and of which it seems a spur, that we will venture to say nine strangers out of ten would walk through it in the full belief that it was a natural rocky pass in the grounds, if they were not asked to wonder at it as a work of art and labor. It was probably more new and raw when Mr. L. obtained his impressions. It is hardly worth while to inquire as to the cui bono of such gardening fancies - for Chatsworth is not a model of rural economy, but of prodigal magnificence of landscape embellishment. Ed.
