_Crown, or Bark-Grafting_ is a very ready method of grafting upon large, uneven, old stocks and branches. It is practised somewhat later than the methods above described, that is, from the end of March to the third week in April, because, in that period, the separation of the bark from the wood is more easily affected; a circumstance of primary importance in this case. The tree is to be headed down, the cut being made horizontally, and the section bored quite even and smooth; then make a slit in the bark two inches in length, next with the handle of a budding-knife, carefully open the bark for about a quarter of an inch; then cut the scion about two inches in a sloping direction, in the form of a tongue, leaving the bark entire on the outside. The scion thus prepared, is pressed downward between the bark and the wood as far as the incision in the stock extends; the bark of the stock readily yields to the pressure employed, and the scion is supported in its situation by a few coils of bass-matting, the whole being surrounded by clay. _Dove-Tail Grafting._--This is a very neat and successful mode of grafting, originating with Mr. Malone, who gives the following directions for its performance. The scion is to be selected so as to have two or three buds above where the knife is to be inserted to prepare it for the operation; a slip is cut off the end of the scion, sloping it to the bottom as long as it may be decided to insert it into the stock. On each side of the cut, as far as it extends, a part of the bark is to be taken off, leaving the under part broader than the upper, on which upper or back part always contrive to leave a bud. The stock or branch to be worked is thus prepared: Being first cut off smooth and straight, two parallel slits, distant from each other nearly the width of the scion and the length of its cut part, are then made in the bark of the branch, observing particularly to slope the knife, so that the under edge of the cut next the wood may be wider than the outer edge. The piece of bark between the slits must then be taken out, separating at the bottom by a horizontal cut. The scion will then slide into the dove-tail groove thus formed, and, if the work is well performed, will fit neatly and tightly. A small quantity of the grafting-clay must then be carefully applied, securing it on with list, or any other convenient bandage, fastening it at the end with two small nails. The top of the stock should be entirely covered with clay, sloping it well up to the grafts, and should be examined often to see if any cracks or openings appear, which should be immediately filled up with some very soft clay. The proper time for performing the operation is from the beginning of April till the middle of May, or earlier if the sap is in motion. (Gardener's Magazine, Vol. VII.)
