tree requires a large space, and produces the worst timber. Planted as nurses in 
young plantations of deciduous trees, they are easily kept within due bounds, by 
a very simple method of pruning, practised by Mr. Billington: viz. by pinching 
off, from time to time, the leading buds of the branches.— J. Main, Card. Mag. 
Successful Experiment, tried by the Author of Gleanings in Natural His¬ 
tory, for transplanting large trees in Bushy Park, in 1831. The plan is as fol¬ 
lows excavate the earth at some distance from the tree, leaving all the princi¬ 
pal 'fibres, and the earth adhering to them, in a compact ball, undermining as 
much as possible, and taking care not to shake or injure the ball by twisting the 
stem of the tree, or using it as a lever to loosen the tap roots: when this is done, 
and a hole made where the tree is to be placed, adopt the following mode: 
—Two pieces of iron must be previously formed, of the breadth and thickness of 
a common cart-wheel tire, three or four inches wide, rather more than half an 
inch thick, and about six feet long* bent in the form of (Fig. 123,) which will 
reduce it to three feet aeross. This will do ^23 
for trees requiring from two to four men to 
lift them; but a size larger and stronger in 
proportion will be wanted for trees, which 
will require eight or ten men or more to 
carry them. Put these irons under the ball of earth, as near the centre as possi¬ 
ble, leaving a space between them of about two feet, and for larger trees a little 
more ; run two strong poles about eight or ten feet long, and three or four inch¬ 
es in diameter, but smaller at each end. Apply these poles, as shewn in the 
sketch, (Fig. 124, a) to each side, passing them through the bends of the irons, 
so as to form a complete hand-barrow, the tree may then be lifted,
