The scene is a quiet country district, with fields and hedge-rows, not looking a bit like war and bloodshed, and the time is a summer afternoon, hot, for it is July, and a haze is over the mountains, which rise a little way behind, as silent witnesses of the fray. The sun begins to decline, and as the air grows cooler the army has orders to start. There is a short delay of preparations, and then the warriors pour forth; not in confusion, but in a compact, unbroken column, each keeping to the ranks in perfect order, and never diverging from them. At first the army follows the high road, but ere long it passes through an opening in the hedge, and crosses the field on the other side. Still the soldiers march on, never hindered, never straggling out of place. It must have been a clever commander-in-chief to have trained them into such admirable obedience. Presently a fortress rises before them--_that_ is the object of their expedition; rather, it is something within the citadel that they are sent to get, and have it they _will_. Not without a struggle, though, for the enemy is on guard, and when he sees the hostile army approaching, he sallies out to battle. He has no idea of surrendering without a fight for it. The invaders gather up their forces and charge bravely up the hill, and in an instant, hand to hand, or something very like it, the foes are locked together in desperate conflict. Neither have they any guns, but they carry sharp weapons with them, and soon the field is strewn with the dead and dying. The fight thickens--the issue is doubtful, but not long--the defenders are routed, and the assailants press forward to the citadel. Most skillful are they, for with neither cannon nor battering-rams they speedily make a breach in the walls, and in they rush, pouring through the street and lanes of the devoted city. Yet they do not destroy it--they do not kill the inhabitants--they do not even stay within the walls so hardly won. In a very short space of time they return as they came, save that each bears a portion of the spoil for which they came. They form in order once again, they march in line, they regain their own quarters, but each one carrying--would you believe it?--a _young slave_. [Illustration: {ANTS HEADING OUT ON AN EXPEDITION.}] Yes, the army did not care to conquer the strange city; the expedition was organized solely and entirely that they might steal the young and bring them up in their own colony as slaves. For, through the long influence of evil habits, the race to which these warriors belong have lost their natural powers, and so have now to be waited on, fed, and altogether taken care of by its slaves. With food before them they would starve unless the slaves put it into their mouths.
