TESTIMONY OF JOSEPH T. O'CONNOR. 159 



Q. What breed of cattle ordinarily gives the heaviest specific 

 gravity of milk ? A. I can hardly say breed ; I believe what are 

 called common cows give heavier milk. 



Q. From what kind of cow did the lightest milk you examined 

 come ? A. That I am unable to answer ; simply, I have forgotten ; 

 the report will show and with that to refresh me, I will answer it. 



Q. Did you examine any cows of the pure Durham breed ? A. I 

 examined cows that were told to me by the superintendent to be of 

 pure Durham breed. 



Q. I find in your report that one cow referred to in the dairy of 

 Thompson, Dairy C I am now referring to Isaac Thompson as 

 having been a pure Durham ; is that correct? A. If it is in the re- 

 port it is just as given to me, but whether she was pure Durham or 

 not, I do not know. 



Q. I find the specific gravity of the milk of that cow stood on 

 July 10 at 93 ; is that correct ? A. That statement is correct. 



Q. You visited this place on July 1st, and again on July 10th, 

 did you not ? A. Yes, sir. 



Q. State the difference in the condition of the cattle on the two 

 occasions ? A. I did not look for any differences and of course did 

 not perceive any. 



Q. Do you think from what knowledge you have on the subject 

 of the condition of these cows that they were more likely to be un- 

 healthy on July 10th, than on July 1st ? A. That is- a question that 

 could not be answered by yes or no. 



Q. Can you state any reason for supposing the condition of these 

 cows on July 10th to have been different from what it was on July 

 1st ? A. There might have been reasons. 



Q. Can you state any? A. I might state reasons in both direc- 

 tions why they might have been worse or why they might have 

 been better. 



Q. Give us one or two ? A. The increase of the temperature 

 might have had its effect ; some animals have gotten used to it on 

 the one hand and on the other hand animals which on the first on- 

 set of the hot weather were not affected might have become serious- 

 ly affected in the space of 10 days. 



Q. At Dairy C, Isaac Thompson, I find that on July 1st the milk 

 of cow No. 3 stood at 96 ? A. Yes, sir.
