of a house, nineteen feet by thirteen, on 

 which are placed twelve stages, and 

 three vases, (D D D) basins, or any other 

 suitable ornamental article, with a gang- 

 way betwixt them three feet wide. 



"The plan also shows sections of 

 three different modes of constructing 

 the stages, and the position of the pots 

 in each; all the stages stand upon stone 

 tables, resting upon brick piers, the top 

 of each table being two feet two inches 

 above the level of the floor. i 



" In the stage (A) there are no 

 shelves, the pots being plunged into 

 cylinders (made of the same material as 

 flower pots) standing upon the tables, 

 as shown by the dotted lines; the space 

 all round them being filled with compost 

 level with the rim of each series of pots. 

 The object of this plan is to afford op- 

 portunities of planting various creepers 

 round each of the potted plants, for 

 which there will be plenty of room 

 when they stand twelve inches apart 

 from stem to stem. The pots are sup- 



posed to rest by their rims upon the 

 edge of the cylinder, and may of course 

 be removed with the greatest facility. 



"In the centre stage (B), the sup- 

 porters stand directly upon the table, 

 and are connected to it, the space be- 

 tween each being made water-tight, and 

 filled up solid to within half an inch of 

 the bottom of the pot. If an inch deep 

 of water is poured in this space, the 

 pot will be immersed half an inch; a 

 small hole in the side will regulate the 

 height of the water line, and another in 

 the bottom will draw off the water 

 when it requires changing. This mode 

 of construction may be adopted for 

 such plants as need large supplies of 

 water. 



" The stage (C) is supposed to have 

 shelves pierced with holes to receive 

 the pots, which rest upon their rims. 

 The stages in my little green-house are 

 so fitted up, and have been by many 

 practical men, who prefer this plan of 

 plunging the pots into the stages to the
