The lower room had been the assayer's office. The floor was thick with _debris_--part human, from the former occupants; part natural, sifted in by mountain winds. In a sea of red dust there swam or floated sticks, boards, hay, straw, stones, and paper; ancient newspapers, above all--for the newspaper, especially when torn, soon becomes an antiquity--and bills of the Silverado boarding-house, some dated Silverado, some Calistoga Mine. Here is one, verbatim; and if any one can calculate the scale of charges, he has my envious admiration. Calistoga Mine, May 3rd, 1875. John Stanley To S. Chapman, Cr. To board from April 1st, to April 30 $25 75 " " " May 1st, to 3rd 2 00 ------ 27 75 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, Lloyd, 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.
