118 MISCELLANEOUS INTELLIGENCE. 



undertaking their cultivation, owing to the daily and nightly care required 

 during frost, to keep brick flues regularly heated ; and sometimes, owing to 

 the great expense of fuel, and the calculation that the frost would not be 

 severe, a fire has not been lighted some nights at the end of winter, and 

 then all the previous care has been destroyed by the admission of frost to 

 the plants. Now, with Arnott's stoves, any pit or large frame may be made 

 frost-proof; and, as the consumption of fuel is so trifling, a fire may be 

 lighted every night, and the expense not felt. Some caution is certainlj re- 

 quired in purchasing these stoves. I bought two of an inferior construc- 

 tion, and found them both useless. Fortunately, Messrs. Cottam and Hallen 

 had supplied a neighbour with one of the regular construction to heat his ser- 

 vant's hall, a room of large dimensions. This acted so admirably, that I 

 immediately procured one from them; the effects of which I thought it my 

 duty to give you, to register in your legitimate pages. 



Sawbridgeworth. _ T. Rivers, 



As there is at present an anxious desire amongst the public to know what 

 Dr. Arnott's stoves are capable of performing, as regards heat, and as I 

 have six in use, and have paid great attention to the working of them, you 

 may be glad to hear the results. But I now allude more particularly to ob- 

 taining a bottom heat from them for early forcing. I have just erected a 

 pit 20 by 7, and formed an air chamber under the whole length ; on the 

 top I have placed netting works, supported by wood rafters, (iron would be 

 better, but this was by way of experiment) ; on that I have laid turf with 

 the grass downwards, and on that again I have placed dry mould. Atone 

 end is the Arnott stove, the smoke of which is conveyed through the 

 whole length of the air chamber by a small brick flue, four inches in diame- 

 ter, and comes out at the other extremity of the pit. The result is, that I 

 have as beautiful a bottom heat throughout as can possibly be required. 

 How the plants — melons I intend it for this spring, and pines afterwards — 

 ■will grow in it, remains to be proved; but I have no doubt whatever about 

 them in my own mind. I have also three tubes at equal distances, commu- 

 nicating with the air chamber beneath which 1 can open and close at plea- 

 sure to let out the hot air when I have too much. They will be further 

 useful for pouring in water, to prevent the heat from drying up the mould 

 which it might be apt to do, unless some means of that sort were resorted 

 to. I give you this early notice of it in the hope of inducing others to make 

 a similar experiment, as the season is but just commencing, and, by the 

 end of it, we may have some practical men giving us their opinions upon 

 it. The advantages that are derived from it are numerous ; all fermenting 

 materials, which are always expensive for large pits, will be saved; the 

 trouble and all the filth and dirt of renewing linings will be done away 

 with, The expence of the fire cannot exceed twopence in the twenty -four 

 hours, and a stove to answer every purpose may be got for £2. The six I 

 have in use consume just one hundred weight of culm in a day and night, 

 which costs here tenpence halfpenny per hundred weight. One is placed 

 in a pine pit, another in a hothouse applied to a boiler, and the others are 

 in different rooms in the house. The average expence of the whole toge- 

 ther is not twopence per day and night each. 



You will see by this account, that a great deal may be done with them at 

 a very small cost, and that many of the anoyances attending forcing, may 

 be entirely overcome by the use of them. Gaud. Gazette.

On Ink Suited for Writing on Metallic Labels. — In answer to your 

 correspondent Y. M's inquiry in last month's Cabinet, "On Ink suited for 

 writing with upon Metallic Labels;" I beg to inform him that from experi- 

 ence I find in order to be perfectly secure, and to preserve the complete 

 indentification of my plants, that it is absolutely necessary to use the pre-
