for the porduction of milk, and when you don't fill up her stomach before 

 she goes out into the pasture, she can't fill it herself because the flies 

 worry her so, and the little bit she does get is not enough to sustain her, 

 and thus you lose your milk. 



Mr. Gurler: I am worried to death and I find it is most econo.miical 

 by feeding ensilage and feeding it in grass out in the grove where the 

 cows are away from the sun. I c an't keep them away from the flies. I 

 did a little experimental work a year ago last summer dividing the herd 

 keeping a -record of each cow. I have the record' days of several weeks 

 as ray basis. Wheni all were run ning out and fed in the grove and the 

 following week we turned only half of them out and kept the balance in 

 the stable in the dark. To my surprise I didn't get onehhalf enough more 

 milk, I think one-eighth of a pound per cow a day than those who were 

 out in the shade in the grove, the cows being fed the siaime. That is all 

 I have been able to do, I can't figh t those cursed flies. I would rather 

 .contend' with weather 40 degrees below zero, but the flies beat me every 

 time. Another fly incident. You know these men, selling fly killer. I 

 took some home^ — the man was honest; let me take it home on trial. I 

 went out to the farm one day an d applied some to my horses. They 

 stood all right, but had not got back from town before they were as bad 

 as ever. I applied this" remedy t o a portion of the cows and kept track 

 of the weight of milk. Thought 1 was to get something advantageous to 

 the cows. The remedy gave a short relief. We applied it once or twice 

 a day. But by the time we got through milking and let them out again 

 the flies returned to them and seemed to make them all the more nervous. 

 It is all theoretical this idea of killing the flies; I get beat every time I 

 Tun up against the flies. 



Mr. Carpenter: Was there any odor about that remedy that troubled 

 the cow? 



A. No, sir, I would not have that. I have to be carerui m my nigh- 

 grade work. It was put on in the form of a spray. It was unpleasant 

 lor the flies for a short time. If I could keep the cows in the barn and 

 Iteep spraying a herd of sixty cows it might help, but it would keep a 

 man busy all the time.
