brick silo, 23 feet in diameter, and was of bad quality, being- 
black and mouldy. The silo was so large that the feeder could 
only get over the surface once in two days, and then removed 
only about 1 y 2 inches. 
The cattle seemed to eat the ensilage readily. This ensilage 
was fed the year round, and was the only thing to which the 
disease could be attributed, so far as could be observed. The 
cows had been kept on the place for a year, and no new animals 
had been introduced. They were kept in the barn a greater 
portion of the time. The writer is not satisfied that the bad 
ensilage was the cause, but the reasons for attributing to it the 
bad effects are the absence of any other apparent cause, and 
that the disease occurred at the beginning of warm weather, 
when decomposition is apt to take place more rapidly, and from 
the symptoms observed, the opinion was formed that death was 
due to a ptomain poisoning of some kind. 
Following directions, the owner cut down a section of the 
silo, and in this way could utilize the ensilage before it spoiled 
on the surface ; that which appeared to be spoiled was thrown 
away, and no further bad results were noticed. 
It should be noted, that if death was due to ensilage, why 
have not some other of the cows suffered from its effects ? 
The writer confesses to misgivings as to the true cause and 
nature of the disease. If any readers of the Review can fur¬ 
nish explanation, either personally, or through the columns of 
the Review, they will be gratefully received.
