warmth and all the brightness of the July day already shone upon the city. He walked at first in a profound abstraction, bitterly reviewing and repenting his performances at whist; but as he advanced into the labyrinth of the south-west, his ear was gradually mastered by the silence. Street after street looked down upon his solitary figure, house after house echoed upon his passage with a ghostly jar, shop after shop displayed its shuttered front and its commercial legend; and meanwhile he steered his course, under day’s effulgent dome and through this encampment of diurnal sleepers, lonely as a ship. ‘Here,’ he reflected, ‘if I were like my scatter-brained companion, here were indeed the scene where I might look for an adventure. Here, in broad day, the streets are secret as in the blackest night of January, and in the midst of some four million sleepers, solitary as the woods of Yucatan. If I but raise my voice I could summon up the number of an army, and yet the grave is not more silent than this city of sleep.’ He was still following these quaint and serious musings when he came into a street of more mingled ingredients than was common in the quarter. Here, on the one hand, framed in walls and the green tops of trees, were several of those discreet, bijou residences on which propriety is apt to look askance. Here, too, were many of the brick-fronted barracks of the poor; a plaster cow, perhaps, serving as ensign to a dairy, or a ticket announcing the business of the mangler.

With the cessation of the sound of his own steps the silence fell dead; the house stood smokeless: the blinds down, the whole machinery of life arrested; and it seemed to Challoner that he should hear the breathing of the sleepers. As he so stood, he was startled by a dull and jarring detonation from within. This was followed by a monstrous hissing and simmering as from a kettle of the bigness of St. Paul’s; and at the same time from every chink of door and window spirted an ill-smelling vapour. The cat disappeared with a cry. Within the lodging-house feet pounded on the stairs; the door flew back, emitting clouds of smoke; and two men and an elegantly dressed young lady tumbled forth into the street and fled without a word. The hissing had already ceased, the smoke was melting in the air, the whole event had come and gone as in a dream, and still Challoner was rooted to the spot. At last his reason and his fear awoke
