EXTRACTS—SPAYED COWS. 371 
continued fever. The cow was apparently well in a few days, 
and very soon yielded her usual quantity of milk, and con¬ 
tinued to give freely for several years without any intermission 
or diminution in quantity, except when the food was scarce and 
dry ; but a full flow of milk always returned upon the return of a 
full supply of green food. This cow ran in the Mississippi low 
grounds or swamp near to Natchez, got cast in deep mire, and 
was found dead. Upon her death, Mr. Winn caused a second 
cow to be spaved. The operation was entirely successful. The 
cow gave milk constantly for several years, but in jumping a 
fence stuck a stake in her bag, that inflicted a severe wound, 
which obliged Mr. Winrt to kill her. Upon this second loss, 
Mr. Winn had two other cows spayed, and, to prevent the re¬ 
currence of injuries from similar causes with those which had 
occasioned him the loss of the two first spayed cows, he resolved 
to keep them always in the stable, or some safe enclosure, and to 
supply them regularly with green food, which that climate 
throughout the greater part of, if not all, the year enabled him 
to procure. 
The result, in regard to the two last spayed cows, was, as in 
the case of the two first, entirely satisfactory, and fully esta¬ 
blished, as Mr. Winn believed, the fact, that the spaying of cows, 
while in full milk, will cause them to continue to give milk 
during the residue of their lives, or until prevented by old age. 
When I saw the two last spayed cows it was, I believe, during 
the third year that they had constantly given milk after they 
w r ere spayed. 
The character of Mr. Winn (now deceased) was highly re¬ 
spectable, and the most entire confidence could be reposed in 
the fidelity of his statements; and as regarded the facts which 
he communicated in relation to the several cows which he had 
spayed, numerous persons with whom I became acquainted, fully 
confirmed his statements. 
At the time to which I alluded, I endeavoured to persuade 
Mr. Winn to communicate the foregoing facts to the late Judge 
Peters, then President of the Agricultural Society of Penn¬ 
sylvania ; but he was restrained from complying with my request 
by an extreme unwillingness to appear before the public, and 
peradventure his discovery might prove not to be new, or doubts 
in regard to the facts might, where he was unknown, subject 
him to some degree of ridicule. 
The many and great advantages that would result to the com¬ 
munity from the possession of a stock of cows that would be 
constant milkers, are too obvious to require enumeration. 
Should gentlemen be induced, from this communication, to 
make experiments, they will find it better to spay cows which
