a man having a little capital and a good deal of industry is much 
better off than he could be in the old country. Land and stock 
are easily got, and they pay better than any thing else, though they 
produce few fortunes. 
The climate is healthy for all animals. I have not met with a 
single case of glanders, farcy, specific ophthalmia, or influenza. 
Fevers, acute inflammation, and grease, are not common. My 
employment is chiefly from colic, lameness, injuries and accidents 
arising from ignorant and cruel management. Fistula in the 
withers, broken hips, and burusattee, are common ; the first arising 
from bites while the young and old, the strong and weak, are 
running together in herds — the second, from rash driving into 
narrow gates or against trees — the third prevails only in summer, 
or depends on something I have not discovered. It can be cured 
as the cold weather comes in. 
I have met with several cases of a disease in which the bones in 
different parts of the body have become soft, spongy, very vascular 
and enlarged, and brittle. For this disease I have not found either 
cause or cure. It kills, and is supposed to prevail most, in certain 
pastures and in certain seasons. The patient lingers long. 
Catarrh is frequently very destructive among sheep, and the 
scab always. Foot-rot is also prevalent where the ground has 
many swamps upon it. 
The horned cattle are the healthiest of our stock, all of which, I 
have observed, is healthy. 
Cattle are subject to the cow-pox, but require no treatment for it. 
The management of animals is different in almost every respect 
from what you have at home. Canine rabies is unknown, although 
some parts of the bushes are overrun with native dogs.

Every ten days, as is generally noted by breeders, the rabbit 
indicates her desire for the male. She becomes riotous in her hutch, 
stamps with her feet on the floor, and kicks with great violence 
on the sides of her tenement. The external parts of generation 
become red, greatly swollen, and very vascular, and a moisture
