The road was filled with mule trains and long processions of camels.

This reminds me that we have been trying for some time to think what a camel looks like, and now we have made it out.

When he is down on all his knees, flat on his breast to receive his load, he looks something like a goose swimming; and when he is upright he looks like an ostrich with an extra set of legs.

Camels are not beautiful, and their long under lip gives them an exceedingly "gallus"-- [Excuse the slang, no other word will describe it]--expression.

They have immense, flat, forked cushions of feet, that make a track in the dust like a pie with a slice cut out of it.
