HOT-BEDS.

The most simple form of Horticultural structures, and one known in
almost every garden, is the Hot-bed. To persons of experience in their
construction and management, we cannot hope to give any important
information, but having seen in many instances the operations of these
beds imperfectly performed, we offer a few simple suggestions and
directions which will be of advantage to the novice.

The location of the bed should be, if possible, a sheltered one,
especially on the north side, while towards the east and south it should
be open. This shelter or protection is needed chiefly to prevent an
undue radiation of heat from the glass, and the entrance of a strong,
cold current of air when the sashes are lifted for ventilation. This
radiation is not only hurtful to the plants by causing sudden and
extreme changes of temperature, but, if allowed to proceed too far, will
cause the heat of the bed to "run out." Let the shelter, therefore, be
as thorough as possible.

We have found the south side of a barn, or a tight board fence a good
location. The barn would be preferable, on account of its proximity to
the materials that furnish the source of heat--the manure pile.

If the soil is wet, or of a heavy nature, it would be better that the
bed be made entirely upon the surface. If the situation is a dry one,
and the soil gravelly or sandy, then a pit may be excavated, of the size
of the intended frame, and three feet in depth. A hollow brick wall
should be built up from the bottom, six inches above the surface, if it
is intended that the bed should be permanent; otherwise the excavation
may be lined with boards, or if designed for only a season's use, it may
be left without any support. Hot-beds made under ground require less
material, are more lasting in their heat, and require less attention
than those built on the surface. On the contrary, should the heat fail
from any cause, beds built up on the surface possess the advantage of
being more easily renewed by the application of fresh fermenting
materials, or "linings" as they are usually termed.

About the 20th of February is early enough, in this latitude, to gather
and prepare materials for the hot-bed. Fresh stable manure alone may be
used, though preference is
