Still, save that the wind outside swept sharply around the corners of the old structure, moaning about the eaves and whistling dismally in at knot-holes. Still, save that now and again it seemed to quiver on its foundations when some especially heavy thunder-clap roared overhead, while the momentary flash revealed the dusty, cobwebbed interior. One standing, by chance, at the door of the mill that opened on to the road, might have espied, in one of these sudden illumings of the night, a farm wagon, drawn by a tired horse, splashing along the road past the mill, and turning off, just below it, on the road leading to the house on the hill. The driver, a tall, spare man, thin-faced and stoop-shouldered, sat with head bent forward, to keep the rain from beating in his face. He was letting the horse, familiar with the way, pick the road for itself. All at once, however, he sat upright, drew the reins in sharply, and peered back in the direction of the mill. "Well, I'm jiggered!" he exclaimed. "If that isn't the mill. I must be crazy. It can't run itself. Yes, but it is, though. What on earth's got loose? It's twenty years and it's never done a thing like that. Back, there. Back, confound you! I'll have a look." The horse most unwillingly backing and turning, headed once more toward the main road, and then was drawn up short again. "Well, I must have been dreaming, sure enough," muttered the driver. "I don't hear anything now. Well, we'll keep on, anyway. I'll have a turn around the old place. There's more there than some folks know of. I'll see that all's safe, if it rains pitchforks and barn-shovels. Giddap Billy." A few moments later, Henry Burns and Harvey, having tucked themselves snugly in among the meal-sacks close by the fire, with the lantern extinguished, roused up, astounded and dismayed, at the sound of carriage wheels just outside, and the click of a key in the lock of the door. They had barely time to spring from their places, and dart up the stairs that led from the middle of the main floor to the one next above, before the door was thrown open and a man stepped within. They were dressed, most fortunately, for canoeing; and they had gained the security of the upper floor, thanks to feet clad in tennis shoes, without noise. Now they crouched at the head of the stairs, in utter darkness, not knowing whither to move, or whether or not a step might plunge them into some shaft. "It must be Ellison," whispered Harvey. "What'll we do?" "Nothing," answered Henry Burns, "and not make any noise about it either. He heard your ship, Jack. Sh-h-h. We don't want to be put out into the rain again."
