206 Account of the Camellia House and Stove. 



enter from the stove, have, also, stop-cocks fitted in, so that the 

 latter may be warmed to a greater degree than the former. To 

 illustrate more planly the course of the steam pipe, which, Mr. 

 Wilder states, is of great use and works with perfect safety, we 

 have annexed the following plan. The pipe runs from the boiler 



underneath the walk into the back of the pit (Jig. 7, a), and con- 

 tinues round to the same end of the pit, and is carried out at the 

 opposite corner (b) into the ciss-pool. The pit is built and filled up 

 in the following manner : — the bottom was first paved with bricks, 

 inchning it towards the front, where a drain, formed by leaving out 

 one row, carries off all water ; the steam pipe is laid on this ; above 

 are nearly three feet of stones, and on them the soil to the depth of 

 two and a half feet. Rotten bark or leaves may constitute part of 

 the soil with which the pit is fitted up. The construction of the 

 furnace, boiler, &c., is so similar to that in Mr. Sweetser's green- 

 house, of which a plan was given in our January number, p. 26, 

 that there is no necessity of annexing an engraving. 



The back wall of the range is coped with plank, and the upper 

 sashes slide underneath two or three inches ; to prevent the rain 

 from driving in, a lead lap is nailed on the whole length. The up- 

 per sashes, only every third one of which is movable, are fitted 

 with weights and pullies and can be opened or closed with ease. In 

 the interior of the range we noticed one thing which is an improve- 

 ment upon green-houses in general ; the front and ends of both 

 back stages, and the back and ends of the front one, in the conser- 

 vatory, are covered with lattice work, formed of laths nailed on in 

 one direction, about half an inch apart ; this prevents persons who 

 are walking through the house, from seeing directly under the 

 stages, and has a very neat and clean appearance. The arrange- 

 ments of the back shed are such as give the greatest facility for the 

 work that is to be done. 



Some estimate of the consumption of fuel through the winter 

 season, and a few other particulars we intended to have added, but 

 not having been able to procure the memoranda for the purpose, 

 we leave them until another opportunity. We have been prom- 

 ised any information in regard to the management of the house and
