A correspondent says " he has a large pear tree on pear roots standing in deep, loamy clay soil, and that while it grows freely, it does not set any fruit," and "asks about root pruning it, how and when."

With Mr. Rivers, whose valuable little work on pears should be in every one's possession, we think there is very much yet to be known about root pruning, and perhaps the advice we now give would not be sustained were we to see the tree. But as it is, we shall recommend that as soon as the terminal buds of this season's growth have formed or are forming, a trench be dug around the tree, two thirds in circumference the diameter of the branches. Dig down deep, so deep that you can, by opening a trench toward the body of the tree, get in a position to cut the tap root off about eighteen inches under ground, then with a sharp knife trim each end of the roots around the inner side of the trench, and again fill in the soil. Make sure that no strong lateral roots or duplicate tap roots are left uncut.

Broccoli and cauliflower can be grown almost as easily as cabbage. Dig the ground deep and supply it freely with well-rotted manure, and keep setting out young plants all along until early in August. The heads will come in freely and to your taste for the table, same as peas, along in order.

Foliage in Trees or plants bearing fruit we believe to be quite as great an item in detecting and deciding varieties as any item connected with the science of pomology. Looking over our currants a few days since when pointing this item out to one of our young friends in horticultural studies, he at once drew our notice to the peculiar shades of color in the foliage as well as the form of leaf of the currants, and at his request we have roughly drawn out these two, Cherry and Red Dutch.
