except Fall Rivor, where it remains about the same, 22 cases 

 having been killed there in 1908, and 24 in 1909. 



In Lowell only 7 cases were found, of which G were re- 

 ported by the agent of the Cattle Bureau detailed to examine 

 the horses sent there to the Thursday auction ; of these G ani- 

 mals, 5 came from outside of Lowell, 1 each from Ma^^nard, 

 jMethuen, Somerville, Lawrence and JSTashua, N. H., leaving 

 only 2 horses that were owned in Lowell, as compared with 26 

 horses the previous year, 19 killed as Lowell horses, and 7 

 found at the auction stable by the Cattle Bureau agent. 



In Worcester, where there were 2G cases in 1908, there 

 were but 14 cases during the year ending Nov. 30, 1909, 

 Several years ago as many as 100 cases of glanders and farcy 

 have been found in Worcester in a single year. 



There is practically no glanders in Massachusetts west of 

 Worcester. Occasionally a horse" with this disease may be 

 purchased in Boston or in New York by some farmer, taken 

 home by him to a country town, and thus start a small out- 

 break of this malady ; but these outbreaks are as a rule easily 

 handled, and are soon stamped out. 



Eighty-four stable tests have been undertaken during the 

 year, 35 cases of glanders having been found in these stables 

 previous to making the tests. Three hundred and eighty-three 

 horses were tested with mallein ; of these, 157 were released 

 after the first test, 50 after a second test, 110 on subsequent 

 tests, 49 were killed after the first or subsequent tests, and 17 

 are held for further tests. 



Mallein does not always seem to be infallible, as in one in- 

 stance a horse that failed to react had a discharge from the 

 nose that infected with glanders guinea pigs which were in- 

 oculated with it; and in another instance a horse that had 

 reacted to mallein every year for the last three or four years, 

 in a stable where an outbreak of glanders occasionally occurs, 

 was killed, and was found to show so little indication of 

 disease that the owner will have to be reimbursed by the Com- 

 monwealth. 



In many instances the inoculation of guinea pigs seems to 

 be of great value in deciding doubtful cases. This work, as
