forage of one part of the country, it removes to another, and from that to a third. In the dry season it comes down to the banks of the rivers; in the wet season it retires to the upper country. When such a nation goes to war, the warriors will not trust their herds and flocks to the feeble defence of their old men, their women and children; and their old men, their women and children, will not be left behind without defence and without subsistence. The whole nation, besides, being accustomed to a wandering life, even in time of peace, easily takes the field in time of war.

Whether it marches as an army, or moves about as a company of herdsmen, the way of life is nearly the same, though the object proposed by it be very different. They all go to war together, therefore, and every one does as well as he can.
