 an iron or copper tray, (the pots be-

 beneath which is soldered a convex 

 round piece of sheet copper, so as 

 to form a flat boiler beneath the tray. 

 A tube through the tray above admits 

 filling the boiler and allows the escape 

 of the steam ; a small tube and cock 

 below allows the water to be drawn 

 off. A lamp placed under the boiler, 

 heats the water and keeps the plants 

 sufficiently warm.

 light. It likewise occupies but little space. The shelves may be so made 

 that all the water thrown upon them, and over the plants, by means of a
