“I guess we’d better shut up,” grinned Bob. “We may get thrown out on our ear.”

Mr. Lewis had studied the map of Algiers and had no difficulty in finding his way out of the city and to Maison Carrée, which might almost be called a suburb of the metropolis. From here they went almost straight south and soon came to a narrow river, which was spanned by a small bridge.

“Scarcely any curves from here on,” said Mr. Lewis, as he increased the speed of the car.

The road remained good, and in a short time they reached Arba, their destination. Here for the first time they caught a glimpse of a camel caravan, for they are never seen as far as Algiers. It was composed of about ten dromedaries, with only three riders. Strapped on the brutes’ backs were packs containing probably dates and other products of the desert.

Bob and Joe took in the scene with intense interest, for soon they would be fitted out in a like manner for the long desert journey. The youths were particularly anxious to observe the manner in which the brutes are ridden. They had heard that to straddle a camel and be able to bounce freely along was an art that came only of long practice. Whether this was true they did not know but resolved to find out sooner or later from Fekmah.

“I’ll bet it’s harder than it looks, though,” remarked Joe.

A little later they saw other caravans of donkeys, the usual beast of burden used near the coast.

“The Arab, unlike other natives, never carries his load,” explained Mr. Holton. “I guess he thinks it lowers himself too much.”

They drove on into the town and had more trouble finding good streets than in Algiers.
