MISCELLANEOUS INTELLIGENCE. 



QUERIES, 



On Dr. Arnott's Stove.— H. W. requests Mr. Harrison to inform hira 

 in the nextnumber of the Floricultural Cabinet, whether Dr. Arnott's Stove 

 will heat a greenhouse properly, and which is the best house in London 

 for buying one? 



We have not had an opportunity of seeing Dr. Arnott's Stove in opera- 

 tion to a plant house, but having been supplied by correspondents with the 

 following remarks upon the subject, we give them J'or the information of 

 our correspondent : 



Having recently built a new greenhouse, and feeling unwilling to incur 

 the expense of fixing a hot-water apparatus, yet anxious to spare the great 

 expenditure of fuel, occasioned by brick flues, my attention was turned to 

 Arnott's stove as a medium. Accordingly, in last December, 1 procured 

 from Cottam and Hallen,one of their 18-inch stoves, which is now, and has 

 been since then, .in constant operation. My new house is 60 feet long, by 

 .12 feet wide, with a span roof; the stove is placed at one end, within a few 

 feet of the door. To explain why I had it placed at the end, rather than in 

 the centre, let me here say that, feeling rather sceptical as to its efficacy in 

 engendering sufficient heat, I had built at the other extremity of the house 

 a common brick flue, 20 feet in length in case of exigency. I will now give 

 the result af my observations. 



During the frost of the 8th and 9th instant, with the assistance of one 

 hour's healing of the flue in the evening with brushwood, the thermometer 

 was kept up to 50 degrees, and, of course, the frost completely excluded. 

 Still wishing to ascertain with greater exactitude the capabilities of Arnott's 

 stove. I have had, during a very sharp wind frost, nearly 30 feet of the 

 bouse next the stove partitioned'off by mats, so as to give me a small green- 

 house, 30 feet long, 15! feet wide, and 10 feet high. In this bouse, then, 

 has the stove given all day, with a moderate fire, and the consumption of 

 not quite a peck of coke, from 50 to 60 degrees of heat. To take off the 

 arid and rather harsh nature of this heat, I have had a zinc pan of water 

 2 inches deep, and 18 inches square, placed on the stove ; the evaporation 

 of which gives all the softness and moisture that can be wished for. 



It must be borne in mind, that in this trial 9 feet of the glass roof out 

 of 15 feet have been covered with double mats, as is usual in severe frosts 

 with all greenhouses. At this moment, 8 p. m., the thermometer in the 

 open air, is at 28 degrees. In the house of the before mentioned dimen- 

 sions, heated by Arnott's 18-inch stove, it is at 60 degrees 



I hope I have now said enough to convince plant-growers, that for small 

 greenhouses, or even for moderate sized ones, this stove will effectually 

 keep out frost, which, of course, with greenhouses, is all that is required. 

 For plant amateurs, particularly for those who do not keep a regularfgarden- 

 er, is invaluable; for the little attendance requited can be given by a maid- 

 servant. No overheating can take^place, and no danger to buildings is incur- 

 red ; and if the simple prevention is taken, of sprinkling the inside of the 

 stove, when it is cold, with water, to lay the dust, preparatory to cleaning 

 it, not the least particle of dust escapes. This is a great advantage, as 

 all other stoves give so much dust, as totally to unfit them for plant-houses. 

 To nurserymen and dealers in greenhouse plants, thisstove is indeed a boon, 

 f»r what numbers of lovers of greenhouse plants have been deterred from
