sorbing^ what urine and fluid animal matters may fall upon it. Such 

 muck spread in the fall, will be found in the spring, when wanted for 

 the corn lands, an efficient manure. Pigs are the very best manufac- 

 turers of manure if they are only furnished with means. The pig 

 yard should have its supply of muck for them to root in and work 

 over, and into which a liberal supply of weeds, pea-straw, or indeed 

 any vegetable matter may be cast with profit. The pens should be 

 kept clean, and the matters scattered over the yards. If they do not 

 incline to work for a living, sprinkle some dry corn or peas over the 

 muck, and they will soon manifest symptoms of industry, and the 

 habit once acquired is not easily lost. 



In regard to the application of manxires to soils, a few simple prin- 

 ciples, well considered, will furnish the best guide. 1st. The ma- 

 . ,. . nures should be placed in that position where they can 

 of Manures. ^^Qst effectually contribute to the nourishment of the 

 plant. 2d. They should be placed where their decomposition, (if 

 used in the fresh or long slate,) can be completed with the least 

 waste of nutritive matter. To effect what is indicated in the first 

 principle named, the manure must be in the immediate vicinity, or 

 in contact with the seeds. For this purpose, as seeds are deposited 

 near the surface, the manures should be so applied, and deep cover- 

 ing must be considered unsuitable; or if thoroughly decomposed, lit- 

 tle is lost, if no covering at all is given.* To effect the last object 

 named, no fresh or long manures, should be used without covering. 

 All fermenting manures give off more or less valuable matters in the 

 shape of gases, which, when they are covered with earth, are re- 



• The effect, or the relative value of several kinds of manures for the potatoe crop, is 

 very Avell shown in the following experiment made by Young. Manures that afford the 

 most nitrogen, are the most useful; hence those abounding in animal products, are supe- 

 rior to others :
