76 OBSERVATIONS ON UR. ARNOTt's STOVE. 



dimensions are twelve inches long, by twelve broad, and two feet 

 high : it cost me£2. lis., and is fully sufficient to keep up a regular 

 warmth of fifty degrees day and night, with burning the same kind 

 of fuel as in my greenhouse. I have it placed between three show 

 cases, one on each side, not thirteen inches from it, and the other 

 over it, not seventeen inches. The pipe at the back goes six feet on 

 a straight line, through a boarded partition, not ten inches from the 

 back of the stove, then entering another apartment, which it keeps at 

 a due warmth of temperature, and is fixed into a chimney. 



My shop-stove being so much approved, a gentleman, who has had 

 frequent opportunities of witnessing its effects, had one, from the same 

 makers, fixed up in his greenhouse the early part of this winter, and 

 has found it answer to admiration. 



If thy correspondent's remarks had applied to the use of the 

 Chunk stoves in greenhouses, I should have been satisfied.

[We feel very much obliged to our respected correspondent for the 

 practical observations sent us. We insert them with confidence as 

 to merit. We have by us several other communications relative to 

 the same subject ; but being signed anonymously, we could not 

 insert them, as they especially deprecated the system, and, it ap- 

 peared, without giving it a fair trial. Further remarks on the sub- 

 ject, from practical observation, we shall be obliged by from such of 

 our readers as have had the opportunity of proving its practicability 

 or otherwise. We have not had an opportunity of having one of Dr. 

 Arnott's stoves in operation in a plant-house, but from what we have 

 seen and felt of it in rooms, shops, &c, it appears to us that the 

 heated air would be too dry to be suitable to vegetation ; and to 

 remedy which, some lateral flue or flues, constructed of metal, ought 

 to be attached to the stove as at present formed, so as to convey the 

 heat to each side to a desirable distance. Such lateral flues ought to 

 be shallow and broad, and the upper part to be made so as to hold 

 two or three inches deep of water; this would give such a degree of 

 moisture to the house, as to render it beneficial to vegetation. —
