Where is John Stanley mining now?  Where is S. Chapman, within whose hospitable walls we were to lodge?  The date was but five years old, but in that time the world had changed for Silverado; like Palmyra in the desert, it had outlived its people and its purpose; we camped, like Layard, amid ruins, and these names spoke to us of prehistoric time.  A boot-jack, a pair of boots, a dog-hutch, and these bills of Mr. Chapman’s were the only speaking relics that we disinterred from all that vast Silverado rubbish-heap; but what would I not have given to unearth a letter, a pocket-book, a diary, only a ledger, or a roll of names, to take me back, in a more personal manner, to the past?  It pleases me, besides, to fancy that Stanley or Chapman, or one of their companions, may light upon this chronicle, and be struck by the name, and read some news of their anterior home, coming, as it were, out of a subsequent epoch of history in that quarter of the world.

As we were tumbling the mingled rubbish on the floor, kicking it with our feet, and groping for these written evidences of the past, Sam, with a somewhat whitened face, produced a paper bag.  “What’s this?” said he.  It contained a granulated powder, something the colour of Gregory’s Mixture, but rosier; and as there were several of the bags, and each more or less broken, the powder was spread widely on the floor.  Had any of us ever seen giant powder?  No, nobody had; and instantly there grew up in my mind a shadowy belief, verging with every moment nearer to certitude, that I had somewhere heard somebody describe it as just such a powder as the one around us.  I have learnt since that it is a substance not unlike tallow, and is made up in rolls for all the world like tallow candles.

Fanny, to add to our happiness, told us a story of a gentleman who had camped one night, like ourselves, by a deserted mine.  He was a handy, thrifty fellow, and looked right and left for plunder, but all he could lay his hands on was a can of oil.  After dark he had to see to the horses with a lantern; and not to miss an opportunity, filled up his lamp from the oil can.  Thus equipped, he set forth into the forest.  A little while after, his friends heard a loud explosion; the mountain echoes bellowed, and then all was still.  On examination, the can proved to contain oil, with the trifling addition of nitro-glycerine; but no research disclosed a trace of either man or lantern.

It was a pretty sight, after this anecdote, to see us sweeping out the giant powder.  It seemed never to be far enough away.  And, after all, it was only some rock pounded for assay.

So much for the lower room.  We scraped some of the rougher dirt off the floor, and left it.  That was our sitting-room and kitchen, though there was nothing to sit upon but the table, and no provision for a fire except a hole in the roof of the room above, which had once contained the chimney of a stove.
