certain it was safe to advance yet farther, he left one place of partial concealment for the next in his proposed line of march. So far as he could see, there was no other guardian of the yard save the two signs at the entrance, and the only purpose they served was to challenge him. Grown bolder as the moments passed without bringing to light an enemy, the lad advanced more rapidly until he stood, partially concealed by one of the pens, where it was possible to have a full view of all that was being done in this place to which the public were not supposed to be admitted. If the intruder had braved the unknown dangers of the yard simply in order to gratify his curiosity, then had he paid a higher price than the view warranted. The building, which from the street appeared to mark the end of the enclosure, was a structure wherein puffing engines, grimy men, long lengths of moving chains, and enormous iron cars or boxes were sheltered from the sun or rain. In front of it a wooden wall extended down into the water,—a pier perhaps it might be called,—and 14 at this pier, held fast by hemp and iron cables, lay a gigantic steamer built of iron. 14 The intruder gave no heed to the busy men and machinery within the building. The vessel, so powerful, but lying there apparently helpless, enchained his attention until he had made mental note of every spar, or boat, or cable within his range of vision. Then, suddenly, from somewhere amid the chains, and cars, and puffing steam, came the shrill blast of a whistle, and as if by magic all activity ceased. The engines no longer breathed with a heavy clank; cars and chains came to a standstill, and men moved quietly away here or there as if having no more interest in the hurly-burly. One of the weary labourers, his face begrimed with coal-dust until it was not possible to distinguish the colour of his skin, took from its near-by hiding-place a dinner-pail, and came directly toward where the small boy was overlooking the scene. Within two yards of the lad the dusty man sat down, brushed the ends of his fingers on his trousers, rather from force of habit than with any idea of cleansing them, and without further delay began to eat his dinner. The boy eyed him hungrily, looked around quickly to make certain that there were no others dangerously near, and stepped out from behind
