He wants to get in his cartridges and try another shot.
Rhinoceros are truculent, blustering beasts, much the most stupid of all the dangerous game I know.

Generally their attitude is one of mere stupidity and bluff.

But on occasions they do charge wickedly, both when wounded and when entirely unprovoked.

The first I ever shot I mortally wounded at a few rods' distance, and it charged with the utmost determination, whereat I and my companion both fired, and more by good luck than anything else brought it to the ground just thirteen paces from where we stood.

Another rhinoceros may or may not have been meaning to charge me; I have never been certain which.
