No. 3.

It will be noticed that Conifers are mentioned in the third list, and even in nurseries where they are regularly moved the mortality amongst them is very high; and the removal of large Conifers should never be attempted except with a transplanting machine, and expert men to handle it. As a rule, it will be found cheaper and better to buy young plants than to attempt the removal of large ones that have stood for some years without root disturbance. Such flowering shrubs as Spiræa, Philadelphus, Kerria, Ribes, &c., can be safely moved without much trouble, as they make a mass of roots which will hold a good ball of soil unless it is very dry. All are practically certain to live if carefully planted and well watered afterwards.

There are several ways of moving large trees, the simplest and quickest being by a proper transplanting machine, which consists of a framework on wheels fitted with a system of rollers and levers. For moderately-sized trees, say, to about 12 feet high, a two-wheeled machine is sufficient. This is moved by eight or ten men. For trees above 12 feet high a four-wheeled machine is required, with two, or perhaps three, horses to draw it. The first will take a ball of soil weighing from two to three tons, the latter anything to ten tons, or even more.

In preparing the tree for the small machine the ball is made round, and slightly smaller than the width of the machine, a trench being cut round the tree to a depth of 3 feet or so, the actual depth depending on the roots, but the soil should be removed a foot lower than the lowest roots. On no account undermine the ball until the proper depth has been reached. A proper machine-pick is the best thing to use under the ball, carefully working out sufficient soil to introduce a board 6 inches wide and about 1½ inches thick on each side of the ball. The soil immediately under the centre of the ball should be left intact. When the boards are in position ropes are passed under them on each side and led up over the rollers on the machine and fastened, and then by levers the ropes are rolled up, swinging the plant up cleanly and with a good ball of soil. Before putting the ropes under, however, a stout piece of canvas or mat should be tied round the ball with a couple of cords, between which and the canvas seven or eight pieces of narrow flat board should be fixed to prevent the cords from cutting the ball. The rear part of the machine is made to be taken out so that it can be pushed right over a plant, and it should be run on planks on soft ground.

With the large transplanting machine a ball of soil of almost any size can be taken, but the method of preparing it is somewhat different. It should be made nearly square, being rather longer than it is broad. When the proper depth has been reached make a hole about 2 feet wide under the centre of the ball, and running entirely through the longer way of it. Through this hole one, or even two, broad planks 3 inches thick should be passed. On each end of these, where they project beyond the ball, a stout plank is laid on edge, and two others placed lengthwise to fit above the first two. These planks should all be cut to fit tightly into each other. If necessary, owing to the depth of the ball, another tier of planks should be placed above the first to insure stability. The machine is then placed over the plant, and the whole, by means of chains and levers, is swung up off the ground, and then ready to be taken anywhere. This machine, however, should only be used by those who have had experience with it, as it is difficult and cumbersome to handle, and in the hands of novices is liable to cause serious accidents.

Where no transplanting machine exists, other mechanical contrivances must be used to move a large tree. Rollers and planks, a low trolley, or a draw-board, as it is called, are the best. The preparation for removal is the same for these means as it is for a machine, with the exception of getting under it, which varies according to the means employed. For rollers and planks the soil should be worked out directly under the centre of the ball, and planks put through to form a bed to run the shrub or tree on. On these a roller should be placed, working the soil out at the sides so that it is well under the ball, but not going so far under as to undermine it, and cause it to drop over. Above the roller put one wide plank to form the bottom of the ball, and by means of a rope round it the whole can be taken where required. When moving it, however, it is well to raise the rear half by means of a broad lever or a lifting-jack, which, in conjunction with a steady pull on the rope, should start the plant comfortably on its journey.

When a low trolley is used the ball of soil must be firm, and not liable to break to pieces when handled with reasonable care. Having cut out the ball to the required depth, work under it all round, merely leaving enough in the centre to support it. If possible, work off some of the upper soil to decrease the weight, but this depends entirely upon the roots, and the way they run. If small roots are plentiful at the top, little or no soil can be removed, but if they are lower down, then the upper soil may be removed with advantage. Having worked under the ball, lay two stout planks under it well packed up to the centre, and then with two strong poles under the ends of the planks lift the whole on the trolley. If the work is carefully thought out, it is possible to make the actual lifting a very small operation by bringing the trolley close and lowering it considerably.
