Think of a savage wild nature that could will its heart to cease beating! But it's true.
Finally I found I could keep only calves under three months of age.

But to capture them so young entailed time and patience.

For the buffalo fight for their young, and when I say fight, I mean till they drop.

I almost always had to go alone, because I could neither coax nor hire any one to undertake it with me.

Sometimes I would be weeks getting one calf.
