HAVING GONE TO SLEEP in that boat on that night he should on no account have been surprised to wake up in the same boat on the same night; but when it happened he was perfectly a-mazed, and had to see and understand everything afresh. His body was hot on the top and cold on the bottom, and on the whole, not happy with its management. He tried closing and opening his eyes a few times to see if he could conjure up a warm bed, but a mightier conjuration had been wrought on him, and condemned him to this place and time. To call it nightmarish was too easy, for it had all the detail, the lively perversity that nightmares wanted. London – burning, smoking, singing – was still all around. However, he was confronted by a sheer wall of stone that rose up out of the Thames, and was thickly jacketed in all of the unspeakables that flowed in it. Atop that wall was a congeries of small buildings, hoists, large guns, a few relatively small and disciplined bonfires, armed men, but snarls of running boys, too. There was the smell of coal, iron, and sulfur, reminding Daniel of Isaac's laboratory. And because the sense of smell is plumbed into the mind down in the cellar, where dark half-formed notions lurk and breed, Daniel entertained a momentary phant'sy that Isaac had come to London and set his mind to the acquisition of temporal power, and constructed a laboratory the size of Jerusalem.
