Gardening. 334 SCIENCE OF GARDENING. Part Sect. V. Cold Plant-habitations. 1696. Cold plant-habitations, i though seldom or never erected, yet deserve to be men- tioned as resources under certain circumstances. These circumstances may be, a desire to cultivate the alpine plants of Europe in tropical climates, or to cultivate the mosses and ferns of the north of Europe in its more southern countries. 1697. The principle on which a cold house can be constructed in a warm climate must either be that of the exclusion of the heat by coverings or envelopes ; or the abduction of heat by evaporation or contact with cold bodies. Heat will be, to a certain extent, ex- cluded, by forming the house in the ground; by excluding the sun's rays from its roof; by a high wall on three sides, leaving only an opening in the middle of the north side ; and by a double or treble roof of glass to the excavation. A house to be cooled by eva- poration may also be sunk in the ground; or it may be raised above it, shaded from the sun, and over it may be supported a number of shower-pipes (16890, which, by pro- ducing a gentle and continual rain on the glass roof and stone or other sides of the house, would draw off much heat by evaporation. Enclosing it by a line of powerful jets-d'eau would effect the same purpose. To produce cold by abduction, the house might be sunk; its floor supported on pillars; and its sides and bottom kept in contact with a running stream; or, if it could be afforded, ice renewable as it melted. These hints are sufficient to show how cold plant-habitations may be formed in any climate: to enter more at length on the subject would be u
