The next place the expedition reached was Tozar,—a town fairly in the Sahara, and beyond even the farreaching sway of the old _Dominos rerum_ and their redoubtable Legionaries. “Before Tozar,” says our author, “there are a few hillocks, dotted with some majestic palm-trees; affording a delightful shade: and the silvery rivulet, winding its way among these in devious directions, adds to the charm of the scene. As we approached, we found the hillocks and the trees literally covered with men, women, and children,—assembled to witness the entry of Prince Mohammed and the camp, with their shrill notes of _lo-lo-lo-lo_!” Tozar, like the other cities of the Sahara, is in one important feature different from those on the coast. Generally speaking, the streets of all the towns of Barbary, like those in Egypt and Syria, are exceedingly narrow, so that one camel, laden with wood or merchandise, is sufficient to obstruct the thoroughfare. But in the towns of the Sahara the streets are generally very wide,—the object of which is, to allow the furious winds of the Desert, charged with immense masses of sand, to sweep clean through, instead of being checked in their course, and therefore blocking up the streets with their noxious deposit. From these sand-storms of the desert, the coast-towns have little to fear, on account of the intervening mountain-chains robbing those terrible visitants of their deadly burden; and accordingly the inhabitants of the Barbary towns can afford to build their streets very narrow, so as to exclude the fierce rays of the sun,—a luxury which their southern brethren dare not indulge in.
