The qualities of yielding great quantities of ricli milk, and ac- 

 quiring flesli with fecility, are rarely to be found combined in any 

 kind of cattle. But by careful selection and long study, I have 

 formed a -breed tliat do combine these admirable qualities ; they 

 are very large, docile, good tempered, free milkers, supplying a 

 great quantity, rich in cream, and at eight years old, show a ten- 

 dency to fall olf in milking qualities, and acquire flesh rapidly. 

 I have been enabled to cause a heifer of this breed to weigh two 

 thousand pounds at two years old. 



It has been ascertained by physiologists, that all parts of the 

 bodies of all animals undergo an insensible process of renewal. 

 The nails and hair we can see are constantly renewed, as they 

 grow outwardly. The muscles and bones are renewed inwardly, 

 and pass off through the excretions, their place being supplied by 

 matter extracted from the food. This renewal is unfelt by us, 

 still it goes on with great rapidity; and every seven years the 

 whole animal body is renewed, so that not a particle of the old 

 body, blood or bones remain. In young animals the change pro- 

 bably takes place in less time. This fact can be conclusively 

 proved, by an examination of the urine and excretions of any 

 animal, where these chemical compounds may be found; audit 

 is to them the excrements owe their commercial value. I have 

 bred in and in for thirteen years, and my cattle instead of dete- 

 riorating, have constantly improved. When young, they receive 

 such food as will insure good constitutions, and their pastures 

 are frequently changed, that they may feed upon different varie- 

 ties of soil. I am perfectly convinced that the idea so prevalent 

 among breeders, that it is absolutely necessary to change the 

 males, &c., is visionary. But even this may be accomplished 

 without sending to foreign countries, by separating the animals a 

 few miles apart, until the change takes place in their animal 

 economy, and they become renewed in flesh, blood, muscle, sinew 

 and bone; and when again brought together they are different 

 animals in every particular except outward form and color, and 

 are capable of renewing the breed. The same will hold good 

 with regard to the human race. If cousins, for example, are 

 brought up in the same neighborhood, notwithstanding they
