DKAI: Sn; : Haying according tn your re(|iiest visited the dairy district at Elgin, 

 111., I hereby submit the following report of the conditiou of the cattle in the largest 

 dairies : 



On Dr. .1. Tetl'fs dairy-tarni an* forty head of milch cows, twenty-four heifers and 

 ealyes. and one bull. The bull and six heifers and calves are thoroughbred Il<d 

 steins. All of the balance are half and two-thirds grade Holsteins. All are in good 

 condii ion and healthy. 



On (i. P. Lord's dairy-farm are sixty head of grade Durham and native cows, and 

 one Durham bull, \vhich are all in good condition and healthy. 



< HI Frank Wright's dairy-farm are seventy head of milch cows, one-third of which 

 number are grade Durhams, and two-thirds are grade Holsteins. There are also 

 thirty grade yearlings and heifers and one thoroughbred Holstein bull. All are in 

 exceptionally fine condition and healthy. 



On Abel Giftbrd's dairy-farm are sixty head of mixed grades and native cows, in 

 ^ood condition and all healthy, except one cow, sick from overfeeding after calving. 



On C. H. Larkin's dairy-farm are ninety-one milch cows, and thirty calves and 

 heifers ; also one grade Durham bull. The cows and young stock are mixed grades, 

 mainly Durham grades, all of which are healthy and in good condition. 



On F. Stringer's dairy-farm are seventy head of milch cows, natives and grade 

 Durhams; also two native bulls. All arc in good conditiou and healthy. 



On Thomas Bishop's dairy-farm are forty milch cows, natives and mixed grades, 

 an<i one grade Durham bull. All are in good condition and healthy. The rumor 

 haying spread, through the instrumentality of a cow-doctor, that pleuro-pneumonia 

 existed on this farm, inquiry elicited the fact that two weeks ago two cows had 

 died from simple inflammation of the lungs. These animals were raised on the farm, 

 no purchases of stock had been made for the last half year, and the cows on the farm 

 have had no means of communication with any other stock. One of the cows was 

 sick rive days, and the other four days. Post-mortem examination showed that the 

 animals died of acute pneumonia. 



On inquiry it was found that the average yearly loss by death, on each of the 

 farms above-mentioned, have been one animal only;" with the exception of Mr. Gif- 

 ford's diary, the health of the stock during the past year has been good. Mr. Gif- 

 ford's stable arrangement, which is faulty for the lack of ventilation, &c., is no 

 doubt the cause of his more frequently occurring mishaps and diseases. 

 Respectfully, 



N. H. PAAREN.

DR. THAYER'S REPORT ON CATTLE DISEASE AT EAST RINGO, N. H. 



A letter mailed at East Ringo, N. H., July 25, 1881, was received on my return from 

 Nova Scotia, The writer states: 



"I write to say I have in pasture in this place a small herd of cattle, of which two 

 have died, one is still very sick, one not so sick. The symptoms are difficult breath ing. 

 standing with their heads drooped, nose elevated, with copious sweating at the nose; 

 eyes sunken, slight frothing at the mouth. I should like to know what course to 

 follow. I have an idea that they are taken with pleuro-pneuinouia. I would like to 

 hear from you soon. 



" Yours, very truly, 



'HARRISON G. RICE." 



On July 30 I replied, requesting that lungs be sent me. 



August 1 I received a letter .stating: "Since writing, two more have died and are 

 buried. Examined the lungs of one and found the lungs congested, and have no
