houses, in
which he advocated the growth of trees in pots. By this system of pot
culture, we are enabled to remove the trees when the fruit begins to
color, and thus to ripen and perfect it in the open air. The over-growth
of wood is also restrained in this system of culture, the trees being
easily managed and controlled. Great success has, in many instances,
attended this mode of culture in this country. Although it is but a few
years since experiments were commenced here, some of our fruit growers
have acquired such skill and experience, as to enable them to realize
considerable profits from their investments in a money point of view,
besides demonstrating the practicability of the system.

The majority of houses erected for this purpose among us, have been of
the cheapest possible description. While the culture was merely
experimental, this was all well enough; but now that the Orchard house
has taken its place among other Horticultural structures, the same
arguments we have urged against cheap Graperies will apply with equal
force to this class of buildings.

The principal differences between the plans for Orchard houses and
Graperies are, first, the somewhat lower roof of the former, that the
pots containing the trees may stand upon the earth floor or border,
while the foliage may be brought as near as possible to the glass; and
secondly, the very ample ventilation required by the trees, at certain
periods of their growth, and in completing the "hardening off" process
of the wood, and leaves if the trees are to be removed to the open air.

Fruit trees are frequently grown in pots in Graperies. After the vines
have expanded their leaves maturely, and obstructed the light, it
becomes necessary to remove the trees to the open air. The leaves and
new grown wood being very tender, the abrupt change to a different
climate is too great, and they suffer in consequence. In a well
constructed Orchard house, the means of ventilation should be so ample
that the trees may be gradually inured to the change; or if it is
desirable to let the trees remain within the house through the summer,
the access of the air must be so abundant as to give as nearly as
possible that flavor to the fruit which it would acquire if fully
exposed.

some years since by J. S. Lovering, Esq. of which the following
