REMARKS ON VERANDAHS FOR l'LANTS, ETC. ] 03 



from the plants. A novel and economical method of heating such 

 houses, and, indeed, most small greenhouses, would be to place on 

 the top of a German stove a small boiler, placed in the centre of the 

 house, and having the stove so constructed as to allow the smoke to 

 escape under the floor, as is the usual manner in similar stoves used 

 for heating halls, lobbies, &c. From this boiler a pipe should branch 

 off from the right hand, and another from the left, and be carried to 

 any required distance, where they should make a turn, and again enter 

 the boiler. Such an apparatus, being portable, could be removed 

 when not required, and used for a variety of domestic purposes, par- 

 ticularly in a laundry for drying linen, or a harness room for repelling 

 damp, and a variety of other purposes that the ingenuity of the pro- 

 prietor might suggest. 



Verandahs, like greenhouses, conservatories, &c, may be con- 

 veniently heated, if placed over cellars or other underground apart- 

 ments, by having a regular hot-water boiler placed in them, with a 

 conducting pipe rising from its top (which of course must be a fixed 

 one), which would conduct the hot water into a horizontal pipe, 

 placed in a cavity under the floor, and extending to the end of the 

 house, and either made to return under itself or to make the circuit 

 of the house, and again re-enter the boiler near its bottom. It is of 

 no consequence how deep the cellar may be, or how high above it the 

 house to be heated may be placed. However, that as little waste of 

 caloric as possible may take place, we should recommend the per- 

 pendicular pipe to be covered with coarse canvass or sacking, or any 

 other non-conducting substance. 



Neither is it essentially necessary that the boiler be placed directly 

 under the verandah, &c, for if the pipes be covered as above, or 

 enclosed in a wooden case and packed in saw-dust, they may be 

 carried a considerable distance in a slanting or even horizontal position, 

 so long as they are kept above the level of the boiler. 



I have seen many dwelling houses heated by means of hot water, 

 the boiler, &c, being placed in the cellar, or in a chamber constructed 

 on purpose, a niche in the side of a passage, or other more convenient 

 place; when such is the case, a branch pipe is readily conducted to 

 the verandah, and the supply of hot water cut off or let on by means 

 of Kewley's water-cock, as may be required.
