550 THE GREEN-HOUSE. [Oct. 



less hardy on the approach of winter; therefore, on every warm or 

 mild day keep the windows open; and even on mild dry nights, 

 daring the remainder of this month, you may slide down the upper 

 front lights so as to admit a little air at top. But observe to keep 

 the windows close shut in cold weather, frosty nights, and during 

 the continuance of cold rains or fogs. 



It will still be necessary to water the plants frequently but 

 moderately, especially the shrubby kinds; the succulent sorts will 

 not require it so often. 



Pick oft', from time to time, all decayed leaves, and keep every 

 part of the house constantly clean and free from tilth of any kind. 

 . The deciduous green-house plants, such as the Lagerstrcemia 

 indica, punka, granata, or double-flowering pomegranate, Croton 

 sebiferum, or tallow-tree, &c. may be placed on a platform erected 

 at the back of the stage, as noticed in page 90, or they may be pre- 

 served very well during the winter in a dry warm cellar that has 

 windows to admit light, air, &c. as necessity may require. 



Preserving Green-House Plants in Garden Frames. 



There are but few green-house plants of a small size but may 

 be preserved during winter, in great perfection, in garden frames 

 of the following construction. 



The frame should be erected on a bed of earth in a remarkably 

 dry and warm exposure; it should be made of strong planks, four, 

 five, or six feet high in the back (according to the size of the plants) 

 eight or nine inches high in front, and four or five feet wide, with 

 the ends sloping accordingly. The length should be in proportion 

 to the number of plants you have to winter, but at every nine or 

 ten feet there should be partitions or stays in the inside for the 

 support of the back. 



Around this frame you are to form another at the distance of two 

 feet therefrom, made of any kind of rough boards, supported by 

 pots, anil of the same height. The vacancy between both frames 

 is to be tilled up to the top with tanner's bark, dry litter, leaves of 

 trees, or any other substance that will keep the frost from pene- 

 trating to the plants. 



Your frame being thus made, plunge the pots containing the 

 plants to their rims in the inside, either in tan or light sandy earth, 

 placing the lowest in front and the tallest behind, and cover the 

 whole with well glazed and well fitted sashes. During the most 

 severe winter the generality of green-house plants may be effectu- 

 ally preserved in this or the like frame by Laying on, as occasion 

 requires, a sufficient quantity of mats over the glasses, and over 

 these a covering of boards. 



The plants arc to have light and air given to them at every 

 favourable opportunity, and should be treated, generally, as directed 

 for those in the green -house. 



Many other similar contrivances may be made, and with the 

 desired effect, as nothing more is necessary for the preservation of 

 these plants than light, air, a moderate share of moisture, and an 

 effectual protection from the frost.
