De I'E'conomie des Engrais, mi de la Methode de Pierre Jaiiffret, 

 Cultivateur d'Aix. Redige et mis en ordre par N. V. Auguste 

 Lozivy, un des Mandataires-Gerans de rAdministration Jauf- 

 fret, pamph. 8vo. Paris, 1837. 



A collection of certificates from various parts of France in 

 favour of JaufFret's new manure, which we have noticed in the 

 present Number, under the head of France. If certificates in 

 favour of an article are to depended on, there is no want of 

 them in this pamphlet. A company seem to have purchased 

 the patent that was taken out by M. Jauffret, with a view of 

 turning the manure to account as a commercial speculation. 

 They propose to grant licences for making it, to cultivators of 

 every kind, from the market-gardener of a few poles, to the 

 occupier of two thousand acres. The first is to pay three francs, 

 and the latter 900 ! Those who occupy fifty acres are to pay 

 eighty francs. We expect to be able to say more on the subject 

 of this manure in our next Number.

Jauffret* s new Manure. — We have in a preceding page (p. 111.) directed 

 attention to Kimberley's manure, said to be a most extraordinary and valu- 

 able discovery ; and that of JauiFret seems to be a parallel discovery of the 

 same kind in France. M. Jauffret, it appears from PAmi des Champs for 

 December, 1837, died in November last. He was born at Aix, in the neigh- 

 bourhood of Provence, and succeeded to a considerable landed estate there in 

 1798. In its cultivation, finding a great deficiency of manure, he tried 

 innumerable schemes to increase it, till at last he hit upon a certain liquid, 

 the composition of which remains a secret, except to those who have 

 purchased the patent right; and which, poured upon any description of soil, 

 mixed with organic matter, produces fermentation, and rapid decomposition. 

 The ley (lessive) which is poured over the materials to be converted into 

 manure is said to consist of various ingredients, but not to be expensive ; 

 two large heaps of materials to be converted into manure not requiring more
