OCT.] THE HOT-HOUSE. 5T3 



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, and of the same height. The vacancy between both frames is 

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

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

 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 effectually 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 are to have light and air given to them at every favor- 

 able opportunity, and should be treated, generally, as directed for 

 those in the green-house, only kept drier at the roots. 



Many other similar contrivances may be made, and with the de- 

 sired effect, as nothing more is necessary for the preservation of these 

 plants than light, air, a less share of moisture, and an effectual pro- 

 tection from the frost. 



THE HOT-HOUSE. 



PINE- APPLES. 



In the early part of this month the pine plants that are to produce 

 fruit next season should be removed out of the nursery stove, &c., into 

 the fruiting-house ; but previous to this you should take out of the 

 pit all the old bark, if you use such material, and fill it with new fresh 

 tan, previously prepared, as directed last month, page 530 ; observe 

 not to put it into the pit in too wet a state, for in that case it would 

 be a long time before it would come to a kindly heat, and sometimes 

 not at all, so as to answer the end. 



Some people sift the old bark, and use the coarse part with new, 

 about one-half of each j but if you can conveniently procure a suffi- 

 ciency of new tan to fill the pit entirely, it will answer much better 

 for this purpose. 



When the bed begins to heat, and the warmth has reached the
