 niCEPKST MIXK IX GREAT BRITAIN 



Our readers may perhaps recollect, that some 

 time ago a coal pit, said to be deepest m Great 

 Britain, was sunk at Monkwearmouth. to the 

 depth of" 264 liithoms, or 1,5S4 leei below ihe sur- 

 litce ;* and that in November, 1834, Professor 

 Phillips of New York, along with a number of 

 other scientific persons, descended t!\e pit, and 

 made a series of very interesting observations on 

 the variations of the barometer and thermometer 

 in the course of their descent anil ascent. The 

 temperature, by these observations, increased in 

 proportion to the depth, and a thermometer sunk 

 into a hole, drilled to the depth of two and a half 

 leet into the Hoor of the workings, from which hole 

 the air was carefully excluded, after remainiiiir in 

 that position fortv-eight hours, stood at 71.2. 

 Since the date of Professor Phillip's visit, the en- 

 terprising ovvners have sunk it still deeper, and the 

 average temperature has increased to seventy de- 

 gress, a degree of heat which makes it difficult tor 

 the men to work beyond six hours at a time.f In 

 addition to this inconveniencr, a species of fly, { 

 about an inch long, has .appeared, by the bite of 

 which both men and horses are much, annoyed.

Owen's animalized carbon. 



Five or six years ago, Mr. Owen happening to 

 he at Copenhagen, and observing that the emp- 

 tying of the privies, and the bones, and such like 

 domestic refuse, had been for many years, perhaps 

 for centuries, deposited in ibur or five large pits in 

 the outskirts ol' the town, conceived the idea of 

 usinsitas manure. He purchased the contents of 

 all these pits, and is now selling it m the form of 

 compressed powder, as a most' valuable manure, 



* There are more shafts than one at the Consohdation 

 Mines in Cornwall, which are nearly 300 fathoms in 

 depth, or 1800 feet. 



t At the bottom of Wolfs shaft, at the Consolidated 

 Mines, the temperature is said to have been as hi^rh as 



which it doubtless is. In 1835, 700 tons of this 

 manure were sent from the mainifactory at Co- 

 penhagen ; ill 1826, 1600 Ions, and in 18."^7, up to 

 about the middle ol" June, when our inl()rinant, 

 iNlr. Petersen, left Coiienhagen, 3000 ions were 

 exported.

To ihe Editor of the Mark Lane .Express. 



Sir. — I notice in your valuable paper of the 

 15th inst., you allude to the unquestionable and 

 eminent cfiemist, Lavosier, as to the example in 

 cullivatii>g lands on chemical principles. I have 

 had ocular ilemonstration of the (act, both in 

 France and Engrantl ; and am sorry the limit of 

 time prevents me giving you a more lengthened 

 account, which I shall liave pleasure in doing in a 

 short period ; and I beg to state, from the know- 

 ledge I obtained ill France, and regular correspon- 

 dence since I left that country, added to which ihe 

 successful experimenis ihat have been Iblluwed in 

 En<iland ; it will not be difficult to nrove land man- 

 aged vvifih chemical compost we should uliimately 

 [)ro(luce one-sixth more grain and seeds than we 

 do this time, without any additional expence to 

 the larEiier. Relerrinir you to the annexed. 

 I remain, sir. 



Your obedient servant,

IMPORTANT TO FARMERS. 



Patent animalized black, which has proved so^ 

 efl'ectua! in all parts of France, where adopted, for 

 upwards of eighteen months back, possesses the 

 Ibllowing advantages over bone manure : — 



Firstly, It is applicable to the strongest as well 

 as the lightest soils. 



Secondly, One ton is equal to thirty tons of 

 common fold-yard manure; can he drilled with 

 the present drills as used tor corn or seed ; or ap- 

 plied as a top dressing, immediately alter the plant 

 appears above ground. 



Thirdly, The proportion is as half a ton English 

 per hectare French, heing equal to about two 

 acres two roods English land measure. 



Fourthly, Insects do not lotlge in carbonized 

 substances, the animalized black being nothing 

 else. 



Fifthly, To use half animalized black, and half 

 boiled bone-dust, is a certain preventive against 

 insects. 



Lastly, Five cwt. of animalized black costs no 

 more than the same weight of bone-dust, but pro- 

 duces much greater effect, in point of produce, on 

 all soils. 



N. B. It is necessary to state, to prevent mis- 

 understanding, this is a different manure to what 

 is selling for animalized carbon, as a sample of the 

 latter was taken by the writer from a sea-port in 

 England, and given to one of the first French 

 chemists to analyze, who pronounced it not to 

 have a particle of carbon in it, observing, at the 

 same time it possessed qualiti"s superior to bones 

 as the latter he called the refuse of the animal.
