ease is absolutely non-existent among our range herds, and 
also among our breeding herds. There may be a few cases 
among the dairies which have not come to our knowledge, 
but, if so, we have no doubt that they must be imported stock. 
My experience of seven years in this climate leads me to say 
that judicious outcrossing of families hereditarily predis¬ 
posed, and the peculiar advantages of this climate, without 
overcrowding or exposure to other unsanitary conditions, 
cause animals to become, to a very large extent, proof against 
contracting this disease. 
Glanders, as you will see from the enclosed report, has 
existed in the State during ’93 and ’94; twelve in ’93, and 
seven in ’94, but all the cases resulted from an importation 
from St. Louis some few years ago. Very many cases of 
catarrh, simple and malignant, assume a chronic form in this 
altitude, which has many of the characteristics of glanders, 
and we believe in the past a great many of such cases have 
been wrongly condemned for glanders; at the present time 
I do not know of the existence of this disease in the State. 
The people here are thoroughly alive to the danger of gland¬ 
ers, and quickly report any suspected cases. I do not hold 
the view that glanders can be so differentiated by the climate 
of the Rocky Mountain regions that it can assume the extra¬ 
ordinary mild form described by some observers, nor that any 
such form could exist to any large extent, because the great 
changes of temperature, always existing here, would be sure 
to cause a malignancy at times which could not be mistaken, 
and which would distribute the disease to a far greater extent 
than it is now met with. Such cases as have been reported 
as a mild and latent form of glanders, we believe to be nothing 
more than the chronic, malignant form of catarrh above 
noted. This opinion has been verified in Colorado by many 
post-mortem examinations, and by the mallein test. 
“ Except among the garbage-fed hogs near our large 
cities, until last year we have had very little cholera, but last 
year, owing to the drought in Kansas and Nebraska, a great 
many store hogs were brought from these States into Colorado, 
and brought with them the disease to a large extent, and I am
