I had been in a listless state between waking and sleeping, listening to the pelting of the rain against the fluttering canvas of the tent, or dodging the streams of water which flowed underneath it, saturating blankets, and collecting on the mackintosh sheet in pools, when gradually I became aware that the sound of the rain and the noise of its heavy beating on the earth had been swallowed up by the roar of the wind, and by the flapping of tents outside. Presently the sides of the canvas, tucked in under big stones, began to rise, permitting the wind to enter and drive sheets of rain right into one's face; the pegs indicated painful indecision and want of firmness of purpose. The glimpses afforded of the state of affairs outside were little calculated to produce a spirit of resignation to the fate which threatened our frail shelter. The ground had lost solidity. Mud--nothing but mud--flying before the wind and drifting as though it were rain, covered the face of the earth. The storm-fiend was coming, terrible and strong as when he smote the bark of the Ancient Mariner. The pole of the tent bent like a salmon-rod; the canvas tugged at the ropes, the pegs yielded. A startling crack! I looked at my companions, who seemed determined to shut out all sound by piling as many clothes as they could over their heads. A roar of wind again, the pole bent till the "crack" was heard again. "Get up, Smith! Up with you; Eber! the tent is coming down!" The Doctor rose from beneath his _tumulus_ of clothes. Now, if there was anything in which the Doctor put confidence more than another, it was his tent-pole; he believed that no power of Æolus could ever shake it. There was normally a bend in the middle of it, but he used to argue, on sound anatomical, mathematical, and physical principles, that the bend was an improvement. He looked on the pole, as he looked at all things, blandly, put his hand out, and shook it. "Why, man," said he, reproachfully, "it's all right--_that_ pole would stand for ever," and then he crouched and burrowed under his bed-clothes. Scarcely had he given that last convulsive heave of the blankets which indicates perfect comfort, when a harsh screaming sound, increasing in vehemence as it approached, struck us with horror. As it neared us, we heard the snapping of tent-poles and the sharp crack of timber. On it came, "a mighty and a strong wind." It struck our tent! The pole broke off short in the middle, as if it were glass; in an instant we were half stifled by the folds of the wet canvas, which beat us about the head with fury. Breathless and half blind, I struggled for the exit, and crept out into the mud. Such a sight met the eye! The whole head-quarters' camp was beaten flat to the earth, and the unhappy occupants of tents were rushing in all directions in chase of their effects, or holding on by the walls, as they strove to make their way to the roofless barns and stables.
