there are two kinds of cattle lice. The little red fellows are 

 very troublesome to get rid of; the larger black louse is not 

 so troublesome. 



Mr. Marshall. It makes no difference whether they 

 are little or big, they will all go. 



Mr. Lord. I have never had trouble in getting rid of 

 blue lice, but the red lice have troubled me considerably. 

 I have sifted dry dirt along on the shoulders and back. You 

 can open the hair and see them there all alive. They don't 

 keep still, like the blue lice ; they are in motion all the time. 

 I have put on sulphur, and tried one thing and another, and 

 none of them seemed to do any good. I think the best pre- 

 ventive is good keeping. If I keep my stock in good con- 

 dition, in good flesh and good order, they do not have any 

 lice. I have filled my barn with hay and rowen, and I do not 

 expect to see any lice on my cattle this winter. 



Secretary Sessions. Another question: "Can any one 

 tell whether cream has been tampered with before it is drawn 

 from the can?" 



Mr. . • This is a matter of more importance, per- 

 haps, than would seem at first thought. On Monday morn- 

 ing I was informed that the milk from a herd that had been 

 giving from nine to ten spaces of cream very suddenly rose 

 to sixteen. This cream was taken to the creamery, and the 

 butter-maker churned it separately. It took between nine 

 and ten spaces to make a pound of butter, whereas the aver- 

 age of the creamery was six and a half. There has been 

 some little improvement in the cream since, but it has not 

 got back where it was before. Another creamery in West- 

 ern Massachusetts I understand has had the same diflSculty. 

 They finally suspended the party for fifteen days, and that 

 cured him. Now, before taking any action in the case to 

 which I have referred, it seemed to me it was possible that 

 some gentleman could give us a certain way of determining 

 whether or not cream has been tampered with. In this case 

 the cream had evidently been stirred. 



Mr. Dyer. A bit of information came to my knowledge 

 casually about a year ago, that may help the gentleman out 

 of his difficulty. I had a hired man who had been in the 

 employ of a party in Connecticut who furnished cream to
