"Gee!" said Skinny. "What's broke loose, now?"
"Great snakes!" I heard Bill say. "I wish I hadn't come."
Benny didn't say anything, but he grabbed my hand and by the way he hung on I knew he was doing a lot of thinking.
That roar seemed to be the end of the storm, for the rain stopped as quickly as it had come. It began to grow light again and somewhere in the woods we heard a bird singing.
We were glad enough to get out into daylight once more and make our way back to the road.
"Let's see what it was that roared so," I said. "It isn't going to rain any more and Skinny is nearly dry."
We could see great patches of blue sky and knew that the storm was over.
The roaring had seemed to come from the mountain, so we climbed up the road and went into a field beyond the woods, from which we usually can see old Greylock looming up, only looking different, it is so near.
This time we couldn't see him at all. The sky was clear overhead, but clouds still hung about the mountain, shutting him from sight.
Then, as we stood there, the noise came again, only worse this time, and right in front of us. The ground seemed to tremble under our feet and from somewhere, back of the cloud which covered the mountainside, came a mighty roaring and grinding that was awful.
