"Now here's where you'll get your stuff. It's all alphabetical; if you want tomatoes, go to T; if you want salmon--S. Just like a dictionary. If I send you down for thirty pounds of salmon, that doesn't mean thirty cans--see?" "Yes, sir," said Tom. "Make up your thirty pounds out of the biggest cans--a twenty and a ten. There's your opener," he added, pointing to a rather complicated mechanical can-opener fastened to the bulkhead. "Open everything before you bring it up." "Yes, sir." He led Tom from one place to another, initiating him in the use of the chopping machine, the slicing machine, etc. "You won't find things very heavy this trip," he said; "but next trip we'll be feeding five thousand, maybe. Now's the time to go to school and learn.--Here's the keys; you must always keep these places locked," he added, as he himself locked one of the doors for Tom. "They were just left open while they were being stocked. Now we'll go up." That very night, when the great city was asleep and the busy wharves along the waterfront were, for the night's brief interval, dark and lonesome, two tug-boats, like a pair of sturdy little Davids, sidled up to the great steel Goliath and slowly she moved out into midstream and turned her towering prow toward where the Goddess of Liberty held aloft her beckoning light in the vast darkness. And Tom Slade was off upon his adventures. Indeed, the first one, though rather tame, had already occurred. He and Archer, having received intimations that the vessel might sail that night, had remained up to enjoy her stealthy nocturnal departure, and the fact that they did not know whether she would leave or not had only added zest and pleasant suspense to their vigil. They were leaning over the rail watching the maneuvering of the tugs when suddenly a man, carrying a suitcase, came running along the deck. "We're not sailing, are we?" he asked excitedly, as he passed. "Looks that way," said Archer. "Where's the gangway? Down that way?" the man asked, not waiting for an answer. "He'll have a good big jump to the gangway," said Archer. "I guess he was asleep at the switch, hey? What d'you say if we go down--just for the fun of it?" "Come ahead," said Tom. At the opening where the gangway had been several men, including the excited passenger, were gathered. The rail had been drawn across the space, and the ship was already a dozen feet or so from the wharf. Tom and Archer paused in the background, wisely inconspicuous. "Certainly you can't go ashore--how are you going to get ashore--jump?" asked an officer good-humoredly. "You can have the gangway put up," insisted the man. "You're talking nonsense," said the officer. "Can't you see we're out of reach and moving?" "You'd only have to back her in a yard or two," said the man excitedly. "What, the ship?" asked the officer, in good-natured surprise; and several other men laughed.
