SPIRIT OF THE MONTHLIES. 353 



see. The following experiment was recently tried in England : Six 

 pigs of the Norfolk breed, and of nearly equal weight, were put to 

 keeping at the same time, and irealed the same as to food and liltcr 

 for about seven weeks. Three of them were lefi to shift for them- 

 selves as to cleanliness ; the otiier three were kept as clean as 

 possible, by a man employed for the purpose, with currycomb and 

 brush. The last consuined in seven weeks fewer peas by five 

 bushels than the other three, yet they weighed more when killed 

 by seventy-two pounds. 



Northern farmers may talk as they please, but they don't under- 

 stand, or rather carry into effect anything like so good a system of 

 fatting swine as those do at the west. There they commence feed- 

 ing early in September, in a nice grass pasture, with plenty of 

 shade trees, and a clear stream running through it. Here Master 

 Porkibus daily bathes his sleek sides, eats luscious roasting ears to 

 his fill, drinks and walks about, or sleeps at his pleasure ; and the 

 way he contrives to extract the fat from the corn to cover his rotund 

 ribs, is quite charming, completely distancing any other chemical 

 process that the wit of man has yet invented. It is worth a journey 

 of a thousand miles, any lime, to take a look at a small field of corn 

 of five hundred acres, crowning the rich bottoms of the west on one 

 side of a fence, and a little herd of tivo or three hundred lusty 

 grunters making away with it on the other. Indeed, we speak 

 within bounds in saying, that we have seen thousands of acres of 

 corn stretching along these valleys, seeming at a little distance like 

 one continued field ; and we once counted 537 hogs in one herd. 

 Talk about pork and corn in New-York ! Take a trip to the Sciota, 

 the Miami, and the Wabash, and one will then get his eyes open, 

 and know something about them.

INCUBATION. 

 In an impregnated egg, previous to the commencement of incuba- 

 tion, a small spot is discernible upon the yolk, composed apparently 

 of a membranous sac or bag, containing a fluid matter, in which 

 swims the embryo of the future chick, and seemingly connected with 

 other vesicles around it. 



1st Day. In a few hours after exposure to the proper temperature, 

 the microscope discovers that a humid matter has formed within the 

 limits of the embryo. At the expiration of twelve or fourteen hours, 

 this matter bears some resemblance to the shape of a little head : a 

 number of new vesicles also successively appear, foreshadowing the 

 different parts of the future body of the chick ; those first formed, 

 and most easily distinguished, may afterwards be recognized as 

 assuming the shape of the vertebral bones of the back.
