Like a flash the Forecaster's advice in the event of the approach of a tornado recurred to the boy's mind, and he sprang into a full run. Ten yards, perhaps, he ran, then cast a glance over his shoulder to see if Anton were following. He saw the younger lad huddling down by the south-western corner of the club-house. Ross colored with shame. For one second he had forgotten Anton's crippled condition. He whirled on his heel with a speed scarcely less than that of the approaching tornado and darted back for his friend. A dozen strides took him back and he reached down for the younger lad. As he did so, with the corner of his eye, he saw the tornado touch a neighbor's barn. The moaning suddenly swelled into a vicious and snapping roar. The point of the tornado enlarged, as it became filled with the debris of the barn, and Ross fancied he could hear the squealing of the mangled horses. Out from the upper part of the wild whirl, high in the sky, a black spot flew. Thrown at a tangent, it fell, growing larger and more bat-like as it fluttered down, striking the earth with a crash. It was the roof of the barn. All this had happened in the fraction of a second that had elapsed while Ross was picking up the crippled lad, and by the time that he had flung him across his shoulder, the tornado had passed over the neighbor's farm and there was nothing left of the barn but a black bare spot. Before the out-flung roof had struck the ground, Ross was running from the track of the swiftly-moving destruction, with his chum on his shoulder. The boy knew well that in ninety seconds or less, the tornado would be upon them, and while it swayed with a malicious eagerness from one side to the other, as though seeking for its prey, there was no doubt that it was rushing straight at them. Second by second, the moaning grew louder, with an uncanny sucking sound as though the monster were licking its lips over the destruction yet to come. The air grew more oppressive and more still. Twenty yards from the club-house, Ross found Dan'l crouching on the ground, quivering with fright. "Mistah Anton, Mistah Anton," he cried, "we's all goin' to be killed!" "Run, Dan'l!" cried Ross, as he sped past. "Run north-west! Follow us!" White with terror, the aged negro rose and started to run, but before he had gone two yards, his steps slowed down. "Thar's Mammy," he said, aloud. "Ah can't leave Mammy, nohow. Thar's no one to look after her." He turned back with unsteady steps, hurrying towards the negro quarters, almost facing the approaching finger that seemed to point at him as he ran. Ross never looked back. His terror and the terrific heat of the air choked his breathing and he gasped as he ran. A sudden swirl of air clutched at his feet. He stumbled and almost fell. The crippled boy's crutch slipped to the ground. Anton slid to the earth and a second swirl picked Ross's feet from under him and threw him to the ground.
