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.
The draw-board is a handy contrivance for moderate-sized trees or shrubs which will hold a good ball of soil. It is made in two forms. One consists of a piece of well-seasoned oak 3 inches thick, and about 3 feet long by 2 to 2½ feet wide at the widest part, from which it slopes down to a thick end, where a stout swivel-ring is fixed to take a rope. The other form is a kind of trolley, and consists of a frame 3 feet long by 2 feet wide; it runs on rollers that work on bent irons fastened to the framework, the whole standing about 4 inches high. Either of these can be used for moving plants the ball of soil attached to which is not larger than the board. They will take a heavy plant with comparative ease, and are especially useful for moving large Rhododendrons and other American shrubs. To get them under a plant cut out the ball of soil to the proper depth, and work under it from the front, that is, the direction in which the plant is to go, keeping the ball wedged up during the process, _not_ by having a man to pull the top over, but by using wedges or levers underneath it, until sufficient soil has been worked out to allow the board to be inserted. When the board is in position the rope should be passed through the ring and then around the collar, using a piece of mat to keep it from rubbing the bark off, and then back through the ring again. It is well to run the board over planks on soft ground to reduce the labour of pulling.
