In the spring of '92 we put on some eastern two-year-old steers; they arrived, and were turned loose from the stock-yards, in a snowstorm, though it was in early May.

Next morning we found that one had been seized, slain, and partially devoured by a big wolf at the very gate of the stockyard; probably the beast had seen it standing near the yard after nightfall feeling miserable after its journey, in the storm and its unaccustomed surroundings, and had been emboldened to make the assault so near town by the evident helplessness of the prey.
The big timber wolves of the northern Rocky Mountains attack every four-footed beast to be found where they live.

They are far from contenting themselves with hunting deer and snapping up the pigs and sheep of the farm.

When the weather gets cold and food scarce they band together in small parties, perhaps of four or five individuals, and then assail anything, even a bear or a panther.

A bull elk or bull moose, when on its guard, makes a most dangerous fight; but a single wolf will frequently master the cow of either animal, as well as domestic cattle and horses.
