m 



the name of " La Methode Jauffret," and we do 

 hereby declare that the following' is a full and 

 exact description thereof. 



In the method of Mr. Jauffret, a pit or reser- 

 voir is prepared of sufficient size to contain the 

 quantity of prepared lye which may be required 

 by the nature of the establishment. This re- 

 servoir or vat is intended to be a receptacle of 

 water saturated with decomposed animal and 

 vegetable matters, and is further to receive the 

 ingredients hereinafter named ; such water is to 

 be found on nearly every farm, and it may be 

 augmented by the drainings of stables, by dish 

 water, suds, and other substances of a like nature. 



Mr. Jauffret, however, finally prepares his lye,, 

 by which the fermentation of the article to be 

 converted into manure is to be promoted, in the 

 following manner, under various modifications. 



For the conversion of from one to two thou- 

 sand pounds of vegetable matter into manure, 

 he takes about 



200 lbs. of night soil, 



200 lbs. of calcined plaster in powder, 

 50 lbs. of wood soot, 

 20 lbs. of wood ashes unleached, 

 60 lbs. of quick lime, 

 1 lb. of common salt, 

 1 lb. of rough saltpetre, 



150 lbs. of lye or ferment drainings from a 

 Jauffret manure heap. 



These ingredients are, in many cases, to be 

 replaced by others; this lye to be prepared ten 

 or fifteen days before use. The quantity of ma- 

 terials above named, for the conversion of from 

 one to two thousand pounds of straw or other 

 dry vegetable stalks, will answer for about dou- 

 ble the quantity of green vegetable matter. 



In using this lye, the plan of Mr. Jauffret is 

 to steep in it the vegetable fibres, which are to 

 be acted upon by throwing them into the vat or 

 reservoir containing it, and removing it thence 

 at great labor so as to form a high heap in the 

 vicinity of the vat, into which the drainings are 

 allowed to run. 



We have thus given a brief outline of the 

 method of Mr. Jauffret, the same appearing ne- 

 cessary to the understanding of our improve- 

 ments, which consist in our omitting altogether 

 the excessive labor of steeping the materials to 

 be acted upon in the lye, and elevating them 

 from thence to the heap ; and also in the prepa- 

 ration of a lye, which is equally effective with 

 that of Jauffret, at much less cost, and which 

 can be used immediately on its being made, 

 thereby saving the delay of ten or fifteen days, 

 which " La Methode Jauffret" requires. 



We prepare a reservoir to contain the lye as 

 usual, and in the immediate vicinity of this, we 

 make our stacks or heaps of vegetable matter, 

 which is to be converted into manure. 



We give to the ground, where the heap or 

 pile is to be made, an inclination towards the 



vat ; if the ground is a firm clay, it may be 

 merely sloped, and have shallow trenches dug 

 on its surface to conduct the drainings back into 

 the vat; or it may have a flooring of timber, 

 brick or stone, as may be preferred, which may 

 be so trenched as to conduct the whole lowards 

 a central drain. When our platform or flooring 

 i is of clay, we cover the trenches and whole sur- 

 face of it with brushwood or rails, so as to form 

 | a temporary grating that will support the weight 

 ! of the heap, and thus insure a drainage, and the 

 admission of air to the heap from below. 



The materials to be converted into manure, 

 ! we pile up on this prepared platform immediately 

 as it is delivered by the cart?, and this we some- 

 | times continue to do until the heap has attained 

 ; the whole height to be given to it, when, by t ! ie 

 ! use of a pump, buckets, or other suitable means, 

 I we raise the lye from the vat and pour it on to 

 ; the heap, continuing so to do until the whole 

 ! mass is saturated ; we, in general, however, 

 j raise the heap to a height of two, three or four 

 , feet, more or less, and then pour on a portion of 

 i lye, repeating this as the height of the pile is 

 ! increased ; this procedure obviates the necessity 

 of lifting the whole of the lye to the full height 

 ! of the heap. 



j The materials which we employ in making 

 the lye, may be limited to the following, namely : 



!cow, horse, or hog's dung, or night soil, the 

 urine draining from stables, and quick lime. — 

 The ingredients used to be intimately mixed 

 with sufficient quantity of saturated water. 



Two of the kinds of animal dung we have 

 found to answer as well as a larger number. A 

 perfectly good lye will be made by taking one 

 barrel each of two of the species of dung, two 

 of the urinary drainings, one of quick lime, and 

 about fifty barrels of saturated water, which is 

 then to be used as above explained. 



What we claim as our improvement on Jauf- 

 fret's method of forming manure by the rapid 

 fermentation of vegetable fibres, is, first, the 

 forming of the said vegetable matter into piles 

 or heaps, without its being first immersed in the 

 prepared lye, and the subsequently saturating 

 the same by the pouring on the lye in the man- 

 ner set forth.

TO ASCERTAIN THE WEIGHT OF A HOG. 



Mr. John Farrar, of Putnam county, furnishes 

 us with the following method of ascertaining the 

 weight of a hog, which may be of use to those 

 who have a hog too heavy to be weighed by any 

 steelyards at their command. He says it is suf- 

 ficiently accurate for all purposes, except in buy-
