276 ANIMAL REMAINS. 



manure that is equal to about- half its weight cf .he dry manure pre. 

 pared from night soil, which the French call pcidrette. M. Daill} 

 made a comparative trial of these two kinds cf manure, and from 

 actual experiment foimd that 200 parts of the deposite from tb« starch 

 manufactory might be used for 100 of poudretle. Even the water 

 that is used in the manufacture, and from which the substance m 

 question is deposited, is an excellent manure when thrown upon the 

 ground, a circumstance which is by so much the more fortunate that 

 this water by standing putrefies and throws otf most offensive ex- 

 halations. By using the liquor to his fields, at once, M. Dailly pre 

 vents every kind of annoyance to himself and his neighbors, and 

 moreover from his great starch manufactory he realizes in this way 

 an additional profit which he estimates at upwards of £Q0 per an- 

 num. Analysis has shown that 100 of this water from the potato 

 starch manufactory represents 17 of moist farm-yard dung. 



In cider countries, the pulp of the apples that have been pressed 

 is always thrown upon land as manure. At Bechelbronn we reserve 

 it for our Jerusalem artichokes ; in Normandy it is thought excel- 

 lent for meadows and young orchards. Analysis of the pulp of ap- 

 ples grown in Alsace shows that when dry it contains a quantity of 

 azote, which places it on the same footmg as farm-yard dung. 

 .Smclair informs us that in Herefordshire the pulp of the cider press 

 is made into good manure by being mixed with quick-lime and 

 turned two or three times in the course of the following summer. 

 Doubtless the addition of lime will hasten the decomposition of the 

 woody matter of the pulp ; but it strikes me that this will take place 

 rapidly enough of itself in the ground without contriving any means 

 of accelerating tlie process. 



Animal remains. Tlie remains of dead annuals and the animal 

 matters obtained from the slaughter house are powerful manures, 

 which are nmch sought after in places where their value is properly 

 appreciated. iScraps and the refuse of skin, liair, horn, tendons, 

 bones, feathers, &c., all form invaluable manure. The llesh of ani- 

 mals which die, and so much of that of horses that are slaughtered 

 which cannot be used as food ft)r animals, may be dried after having 

 been previously boiled, and then reduced to powder and applied as 

 nianure. The blood of slaughtered animals is less proper as food 

 for hogs, although it is often used in this way, than muscular tlesh ; 

 it even occasionally gives rise to serious diseases among these ani- 

 mals. It is most easily j)repared as manure, however, for which it 

 answers admirably : it is enough to coagulate it by exposure to heat, 

 and then having broken it down, to dry it in the air or in the stove. 

 Liquid blood has been employed as manure, but decompo^iti^)n then 

 takes place so rapidly, that the produc s are exhaled without pro- 

 ducing much elTect. This objection may be remedied by two means, 

 either by diluting the blood in a large quantity o( water, with which 

 the land is then irrigated, or by mixing it with a considerable mass 

 of vegetable earth, which is then applied like ordinary manure. 

 There is even a pulverulent manure of which blood forms the basis, 

 prepared in special establishments in the vicinity of various larpe
