Page 305 - Webb to send me one of his best sheep, and he sent me a shearling by his favourite sheep Babraham, which made some good stock out of my large ewes. I went down the next two years, and selected for myself; but the stock did not suit my taste so well as the one he sent me, and I did not use them. I then commissioned him to send me...
Page 295 - The most probable supposition is, that propagation is done by halves, each parent giving to the offspring the shape of one half of the body. Thus the back, loins, hind-quarters, general shape, skin, and size, follow one parent; and the fore-quarters, head, vital and nervous system, the other : and we may go so far as to add, that the former in the great majority of cases go with the male parent, and the latter with the female.
Page 295 - Such facts as these are sufficient to prove that hight or growth , does not exclusively follow either the one parent or the other. Although this is the case, it is also a striking fact that the union of tall and short parents rarely, if ever, produces offspring of a medium size — midway, as it were, between the two parents. Thus, in the breeding of animals, if the object be to modify certain defects by using a male or female in which such defects may not exist, we cannot produce this desired alteration...

Although in the crossing of sheep for the purpose of the butcher, it is generally advisable to use males of a larger breed, provided they possess a disposition to fatten, yet, in such cases, it is of importance that the pelvis of the female should be wide and capacious, so that no injury should arise in lambing, in consequence of the increased size of the heads of the lambs. The shape of the ram's head should be studied for the same reason. In crossing, however, for the purpose of...
Page 304 - I commenced by drafting all the small and delicate ewes, and the remainder were crossed with rams of the Hampshire breed. I bred from their produce for two or three years, and then had another cross with the Hampshire, still continuing to cull defective ewes. After I had obtained considerable size from the infusion of the Hampshire blood, I had recourse to some rams bred by Mr. Humphrey, of Chaddleworth, Berks, which were the produce of the biggest and strongest Hampshire ewes by s sheep of Mr.
Page 305 - On examining the different breeds exhibited there he found the Cotswolds were beautiful in form and of great size, and on making inquiries as to how they were brought to such perfection...

The action of the purely nitrogenous manures, is economised by admixture with a small quantity of superphosphate of lime, or other appropriate mineral manure. Other things being equal, the later the barley is sown, the less should be the proportion of nitrogen in the manure, and the greater that of mineral constituents ; otherwise the crop is liable to be too luxuriant...
Page 302 - Wilt*, a close observer as well as an excellent' farmer, informs the writer that he, as well as his brother, purchased Mr. Twynam's rams for several years, and has, he conceives, derived advantage from the cross. Mr. Rawlence observes, that the points he has arrived at have been to produce an animal yielding at an early age the largest possible amount of mutton and wool, which he considers the sine qua non of sheep breeding; and he adds, it is difficult to estimate the enormously increased production...
Page 301 - England where none are to be found is probably the exception, not the rule. The Hampshire sheep may, therefore, be instanced as an example of successful crossing, and as a proof of what can be done by the male parent, in changing, in very few generations, the character of the original, and yet retaining some of its good qualities, thus forming a breed more intrinsically valuable than either source from whence it is derived. It has been truly said that the public is wise though composed of fools ;...
