"You notice, I suppose, that this flat spreading out before us at the bottom of the embankment is inclosed on all sides by mountains. They are shaped something like a triangle and we are standing at the base. Here, let me make a rough sketch of it on the back of this envelope. It will help us out a little. There! That figure 1 is the freight depot, near which we are standing. Towering up above us are houses and up there a canvas city for refugees. There is a temporary hospital there, too, and a graveyard, where many a poor victim of the flood lies. The background is a high hill. The people here call it Prospect Hill. The flood! Gracious! what a view the people up the hill must have had of it as it whirled, and eddied, and roared and rushed through the town, for this great flat before us was where the main portion of Johnstown stood. [Illustration] "You notice that there are gaps in the mountain chains which form the sides of the triangle. Through the gap at our left comes the Conemaugh River, flowing from the mountain on its way westward. River, did I say? I don't wonder you smile. It doesn't look much like a river--that little bubbling stream. Can you imagine it swelling into a mighty sea, that puny thing, that is smiling in its glee over the awful havoc it has created? Now you are beginning to understand how it is that Johnstown proper lies within the forks of two streams. The Conemaugh runs by us at our feet to the right. See, there is a wrecked and overturned car down there. If thrown across the stream it would almost bridge it. That is Stony Creek on the other side of the flat, running down through that gap which forms the apex of the triangle. It skirts the mountains on the right and the two streams meet. You can't see the meeting point from here, for our embankment curves, but they do meet around that curve, and then the united rivers flow under the now famous stone bridge, which was built to carry this railroad across the stream. Oh! yes, we will go down there, for that bridge formed the gorge which proved so destructive. Savage Fury. "I would like to take you away up to the dam if we had time and point out the destruction all along down the valley until the flood rushed through that gap to the left and then spread over Johnstown. But it is too late in the day for that, and the walk is a most tiresome one, so you will have to take my word for it. Of course, you have read that the dam was constructed in a most outrageous manner. Well, that is true. It is a wonder the valley wasn't swept long ago. No, the loss of life wasn't great in the upper part of the valley because the people took the warning which the Johnstonians refused and mostly escaped. The little town of South Fork was badly shattered and Mineral Point was swept away.
