APRIL] FLOWER GARDEN. 363 



ferent frames, all of the same length and breadth, and each about 

 nine or ten inches deep, except the upper glass frame, which should 

 be ten inches deep in front, and eighteen at the back ; being all of 

 equal dimensions in width and length, made in a very exact manner, 

 to fit one on the top of another, appearing as but one frame when 

 thus joined, and are to be made use of in the following manner: 



Begin first with the deepest frame ; then, when the plants have 

 reached the glasses, let the said frame be taken up, and in its place 

 set one of the others, and immediately fix the deepest frame upon 

 that, as above ; and then, when they have filled that space, let an- 

 other frame be added, observing, as above, to let the deepest or slop- 

 ing frame be always placed uppermost in order to receive the glasses. 



The glass-cases for this purpose are generally made about six, 

 seven, or eight feet wide, and as long as may be convenient; the 

 height should be five or six feet in front, and seven or eight in the 

 back. 



The front ought to be of glass sashes, perfectly upright, and facing 

 the south; the back may be either of wood or brick, and both ends 

 of the same materials, but if of glass, the better ; and the top must 

 also be of glass sashes, sloping from the back to the front. 



Within this, a hot-bed is to be made, for which a pit must be 

 formed nearly the whole length, raised by brick-work or planking 

 above the floor, having the whole about two feet and a half deep, 

 and from four to five or six feet wide : this is to be filled with hot 

 dung or tanner's bark, carrying it up a few inches higher than the 

 top of the pit, to allow for settling ; and if a dung-bed, lay earth or 

 tan-bark at top five or six inches thick. 



The pots are to be placed upon this, plunging them to their rims 

 in earth, as before mentioned ; but if the bed be made of tan, plunge 

 them therein, having no occasion for earth upon such beds. 



In this frame or glass case, let the plants have fresh air daily, and 

 give sufficient supplies of water, and towards the latter end of May 

 they will be advanced to a large size, and may be removed in their 

 pots into any principal compartment in the pleasure-ground, &c., or 

 placed among the green-house plants. 



When tender or curious annuals have .been omitted to be sown in 

 the former months, a slight hot-bed may be made for them in the 

 beginning of this, to forward them as much as possible. The seeds 

 are to be sown as directed on page 169. 



SOWING ANNUAL FLOWER SEEDS. 



All the varieties of annual flower-seeds that are capable of bear- 

 ing the open air, and of arriving at perfection in our climates, may 

 now be sown with good success. In the early part of the month, 

 you may sow the following kinds with many others too tedious to 

 mention in this place, viz : alkekengi, China aster in sorts, Molda- 

 vian-baum, belvidere or summer cypress, candy-tuft in sorts, LobeFs- 

 catchfly, cyanus in sorts, flos-adonis, bladder-ketmia, heart's-ease, 

 convolvulus tri-color, larkspurs in sorts, lavatera in sorts, and lu- 

 pins of every kind; dwarf lychnis, curled, oriental, and Peruvian
