CHAPTER IV.
ODDS AND ENDS Scent and Instinct--Mules--Roping Contests--Antelopes--The Skunk--Garnets--Leave Arizona.
This shall be a sketchy chapter of odds and ends, but more or less interesting according to the individual reader.
The horse's intelligence is nothing compared to that of the mule, and as riding animal in rough country a mule should always be used.

In Mexico, Central American States and the Andes mules are alone used; and what splendid, even handsome, reliable creatures they are on roads, or rather trails, such as it would be hazardous to take horses over.

I once saw the unusual sight of two big strong mules (our ammunition pack animals) roll together down a very steep hillside.

Happily neither mules nor loads were at all damaged, but it was a steepish hill, as on our returning and trying to climb it we had to dismount and hang on to the horses' tails.

Another good point about mules is that they will not founder themselves.
