only the morning sun. When the stems decay, 

 the roots should be taken up and kept in sand 

 in a dry place, till the time or" planting. In 

 the second year's planting, they should be put 

 in separate small pots. 



The old roots may betaken upeverytwo orthree 

 years, to have the off-sets taken off from them. 



They produce a fine effect and variety in the 

 flower borders and other parts among other flower- 

 ing plants. 



GLASS CASE, a light sort of erection formed 

 with glass sashes, in proper frame-work, mostly 

 upright in the front part and ends, but sloping at 

 top from a back wall, or other convenient build- 

 ing, to the fore part ; the front, top, and both ends 

 being of glass-work. The situation for this 

 purpose should face the south, in order to have 

 the full influence of the sun. Constructions of 

 this nature are useful for protecting many sorts of 

 curious tenderish plants in winter, which want 

 it only occasionally from severe frost, and other 

 similar causes. 



Buildings of this kind may be constructed 

 occasionally, either against some ready-built 

 south wall, which serves for the back, all the 

 other parts forward being wood-work and glass; 

 or detached in a similar situation, so as that the 

 whole front may stand to the south, the back being 

 formed of brick- work, &e. or of wood double 

 planked ; but the former is preferable ; the whole 

 being generally ranged lengthways, nearly east 

 and west. 



The dimensions may be from five or six, to 

 eight or ten feet in width, by ten, fifteen, or 

 twenty feet in length or more, as may be required ; 

 and from six or eight, to ten feet high behind, by 

 five or six, to seven or eight in the front, both ends 

 in proportion with the top, sloping gradually, as 

 just noticed, from the back, having an entrance 

 or door in front, or at one end. The glass- 

 work should be made to slide. 



Sometimes fire-flues are carried along the 

 back and front internally, proceeding from an 

 external furnace, for occasional fire-heat in win- 

 ter, which render them more convenient and 

 useful for different purposes. 



These Cases, as mentioned above, are used as 

 preservatory departments, in which to winter 

 many sorts of curious exotics, of the hardier 

 green-house kinds, which only want protection 

 from severe cold, as well as many choice kinds 

 of the open ground which are rather tenderish 

 in their minor growth, or any other particu- 

 lar or curious hardy plants, whether flowers, 

 shrubs, or young trees, especially the choice 

 evergreen kinds, which require effectual pro- 

 tection from the ravages of rigorous frosts or 

 cutting winds in winter or early spring; and 

 at the same time, in mild open weather, to 



enjoy the full air by opening the glasses; all 

 which, being in pots, can be readily placed in 

 this preservatory at the approach of severe wea- 

 ther, and be thus kept in good condition till 

 settled weather in spring, &c. then removed 

 into the full air: in summer and autumn, when 

 unoccupied in this way, these Cases may be of 

 utility to place some kinds of curious tender 

 plants in when in flower for seeding, to guard 

 them from heavy or incessant rain or cold night 

 dews in autumn, which in many sorts retard, 

 or sometimes wholly frustrate their production 

 of good seed, as in some sorts of curious tender 

 Annuals, particularly the fine Double Balsams, 

 Cock's-Coir.bs, Tricolors, Double Stramoniums, 

 Diamond Ficoides, and various others. 



They are also capable of being used in spring 

 and the early part of summer, as April, May,, 

 and June, as a kind of drawing-frames, for some 

 particular sorts of curious Annuals, to bring 

 them to a tall growth, such as the Large or Giant 

 Cock's-Combs, Tricolors, Double -Stramoni- 

 ums, Double-striped Balsams, Egg-plants, &c. 

 the plants being first raised in hot-beds under 

 garden-frames, till of twelve or fifteen inches 

 growth, then a hot-bed made in the Glass-Case, 

 earthed at top, and the plants in pots singly 

 plunged into the earth of it; the glasses in 

 these cases being shut close, only a necessary 

 admission of fresh air being given every day, 

 by which they run up to a tall stature, in the best 

 perfection of strength for flowering. See An- 

 nual Plants. 



These glass cases are also sometimes made use 

 of as a kind of appurtenances to hot-houses or 

 stoves detached from them, having, as observed 

 above, internal flues for tire-heat when necessary, 

 serving as preservatories for many sorts of exotics, 

 which are tenderer than common green-house 

 plants, but do not require the constanTl'iill heat of 

 the more tender hot-house kinds, but only the as- 

 sistance of moderate lire-heat in winter, in cold 

 nights, or when very damp, cloudy, foggy wea- 

 ther and severe frosts prevail. They are some- 

 times used in the business of forcing different 

 kinds of flowering plants and esculents, either by 

 means of an internal bark-bed, or flue3 for fire- 

 heat. 



When intended for this purpose, it is conve- 

 nient to have both an internal pit for a bark-bed, 

 and flues for fire-heat, in order to use either se- 

 parately, or sometimes both, as it may be found 

 necessary.
