ENZOOTIC ABORTION IN COWS. 113 



about five acres of pasture. Those cows have had nothing 

 from the 15th day of May until the first day of October ex- 

 cept what they have got upon those five acres and corn-fod- 

 der. I have never had cows in any better condition at this 

 season of the year than they are ; I have never had my cus- 

 tomers complain less of poor milk than they have done this 

 past summer. 



I think that the subject of feeding meadows is not properly 

 understood. I prefer to have my forty cows run on that 

 meadow a couple of weeks longer, if they can, and eat the 

 surplus grass that has grown there since haying. 



Mr. Cheever. I would like to ask the gentleman 

 whether the heavy feeding of forty cows on five acres of 

 pasture has injured it severely, or whether it has rather im- 

 proved it? 



Mr. Noble. I change the pasture every second year, 

 plough the land, and some other pie^e is given to the cows. 

 The rankness of the soil begins to produce grass which the 

 cows reject. Consequently, that land has to be cropped, 

 and the cows turned on to another piece, which they very 

 soon bring up to the same condition. 



Adjourned to Wednesday. 



SECOND DAY.

The Board met at 9.30, Mr. Wheeler, of Great Barring- 

 ton, in the chair. 



In the absence of Dr. Billings, Secretary Russell read the 

 lecture prepared by him on abortion in cows.

 the subject which we are about to consider. Abortion is an 

 accident which occurs during pregnancy. It is not a disease,
