No sign, now of paving or car-tracks--nothing save, on the other side of the way, crumbling lines of ruin. As he worked his way among the detritus of the Metropolitan, he kept sharp watch for the wreckage of a hardware store.

Not until he had crossed the ancient line of Madison Avenue and penetrated some hundred yards still further along Twenty-Third Street, did he find what he sought. “Ah!” he suddenly cried. “Here's something now!”

And, scrambling over a pile of grass-grown rubbish with a couple of time-bitten iron wheels peering out--evidently the wreckage of an electric car--he made his way around a gaping hole where a side-walk had caved in and so reached the interior of a shop.

“Yes, prospects here, certainly prospects!” he decided carefully inspecting the place. “If this didn't use to be Currier & Brown's place, I'm away off my bearings. There ought to be something left.”

“Ah! Would you?” and he flung a hastily-snatched rock at a rattlesnake that had begun its dry, chirring defiance on top of what once had been a counter.

The snake vanished, while the rock rebounding, crashed through glass.

Stern wheeled about with a cry of joy. For there, he saw, still stood near the back of the shop a showcase from within which he caught a sheen of tarnished metal.

Quickly he ran toward this, stumbling over the loose dooring, mossy and grass-grown. There in the case, preserved as you have seen Egyptian relics two or three thousand years old, in museums, the engineer beheld incalculable treasures. He thrilled with a savage, strange delight.

Another blow, with the sledge, demolished the remaining glass.

He trembled with excitement as he chose what he most needed.
