Where walls are a good height - say from 14 to 18 feet - instead of planting the trees at from 10 to 15 yards apart, I would recommend to get maiden trees, - that is, one growth from the bud or graft, and plant these at 2 feet apart along the wall, then cut them back to two eyes, training one off at right angles on each side for about 6 inches, thus allowing a foot or thereby between every branch while being trained up the wall. Strong growing sorts might be allowed to have four upright leaders, thus having two trained off on each side. Now it must be very plain to every one that such a mode of planting fruit-trees would be a means of soon covering the wall, and at the same time one can have a greater variety of fruit in a given space, and by well attending to root-pruning there need be no unproductive or rampant growths allowed on the trees. We have seen this tried on a limited extent, and it answered remarkably well, instead of waiting for years, as in the old way of growing trees, to see a good wall moderately filled with productive trees. In this way any one may have a wall 14 feet high pretty well furnished with fruitful trees in from 4 to 6 years.

Of course much depends on soil, situation, and climate.

We have seen this done with Peaches over a trellis in a Peach-house, and the second season after planting, a trellis over 6 feet high well covered with splendid bearing wood. When the price of a few maiden trees is taken into account, it sinks to a mere nothing when compared with the results, and this is far better than the system of pot-culture, with all its liabilities to over-dryness in summer, and consequent dangers from red-spider, thrip, and insufficiently developed leaves, resulting in crippled growth and unfruitfulness. This system, as compared to pot-culture under glass, requires far less careful attention, always looks cleaner and neater, and may be used to any extent where at first a little expense can be allowed for a good return.
