clean, even .shut up as it is at night. If j r ou go into it in 

 the morning you will have a pretty good sense of smell if 

 you can delect the odor of a stable. The air changes auto- 

 matically about every hour, and it is held steadily at about 

 55°. Now, that is the system of ventilation. Care must 

 be taken always that this air is let in down by the wall on 

 the outside, rises up and goes through, and comes in at the 

 ceiling, and the barn must be sweet. You must expend 

 enough to make the barn right, and then you can control the 

 currents of air, and have them go where you want them to. 



Dr. J. B. Lindsey (of Amherst). I simply want to 

 shout amen to what the speaker has said. I could not get 

 over here from Amherst last night, because of the storm, so 

 I sat down and picked up a copy of " Hoard's Dairyman," 

 and I read over the address which Mr. Hoard gave before 

 the Dairvmen's Association in Iowa, wherein he gave the 

 result of his cow census, as he calls it, 100 herds examined, 

 35 per cent of 100 herds kept at a loss ; and I said, " How 

 is it in Massachusetts ? Are we any better oft? " Some- 

 times when I get into a carriage and ride around about Am- 

 herst, or in other sections of the State, I look over the 

 herds and fear for the result. 



Just one point, gentlemen, this summer my friend Pro- 

 fessor Cooley wrote an article in the Massachusetts ' ' Crop 

 Report," where he gave his ideas relative to the dairy herd, 

 and when I had finished reading it I said ; " I wish every 

 farmer interested in that matter could read that little article, 

 because it contains so much that he ought to know." Yes, 

 that you and I as dairymen ought to know ; it contains so 

 much good sense compressed into such a small mass. 



Mr. H. C. West (of Hadley). Is a fat cow better to 

 milk than a lean one, or does feed have any effect upon the 

 product of the cow? 



Kx-Governor Hoard. The question is, does a fat cow 

 give better milk than a lean cow? Sometimes yes, and 

 sometimes no. It all depends on the cow. 



Mr. West. I mean the same cow. 



Ex-Governor Hoard. Would she give better milk when 

 fat?
