No. 4.] CATTLE COMMISSIONERS. 517 



Conn., is practically excluded, for no western cattle are unloaded 

 there, and cattle have since been unloaded there with no danger. 



The possibility of car infection must be admitted until the use 

 of each car through the entire season is proven. Since four dif- 

 ferent local cars were in use, perhaps five, infection must be pretty 

 generally widespread, and car disinfection little practised, if due 

 to this source. While it is my opinion that infection was not due 

 to infected cars in any case, the possibility remains ; a search of 

 the uses to which those cars have been put will reveal whether this 

 infection of either car has been possible. (Note : car numbers 

 furnished by United States Bureau of Animal Industry shows no 

 probability of car infection.) 



The single cow that died in Albany was said to have been " all 

 around the stock yards." Since she had not been in cars, her 

 infection must have been at the stock yards, for there is no other 

 possible source in Albany to which she had access. Quarantine 

 cattle consigned to slaughter houses are said to be unloaded 

 elsewhere. 



A consideration of the facts regarding the treatment of the 

 cattle at the West Albany stock yards, the time at which the 

 disease appeared and the impossibility of their having contracted 

 the disease earlier, forces the conclusion that they were infected at 

 that point. 



On August 1 the cattle of cars Nos. 10028, Rome & Water- 

 town, and 22931, New York Central, were received from 

 Herkimer and St. Lawrence counties, N. Y., and put into pens 15 

 and 16, alley D, respectively. They were forwarded, the first 

 carload to Brighton, Mass., the second to New Milford, Conn., 

 their only point of contact being when they were put into the con- 

 tiguous pens. Cattle from car No. 10028 began dying in ten 

 days thereafter, and the outbreak continued for ten days ; cattle 

 from car No. 22931 began dying in fourteen days, and continued 

 about a week. 



On August 8, cattle from car No. 10033, Rome & Watertown, 

 were received from Jefferson County and put into pen 16 D. 

 Some of these died between ten and fifteen days thereafter. On 

 August 15, cattle from car No. 23015 were also received from 

 Jefferson County and put into pen 17 D. Some of these died 

 between twelve and fifteen days thereafter. 



Of the eighty-five head in the four carloads put in pens 15, 16 

 and 17 at this time, forty-five died in from ten to twenty days 

 thereafter, and the bulk of them died about fourteen days after 

 infection. 



The data pointing to the infection being in these pens accords
