Each of the shipwrecked men in turn wanted to give words to his gratitude, as was only natural, since, save for the exertions of the keeper and his first assistant they would not have been alive; but Mr. Peters was as much opposed to being thanked as was Captain Eph, and the men went on board the dory after silently shaking hands with Uncle Zenas and Sidney. "Don't let Sammy linger 'round on shore any longer than is necessary!" the cook cried warningly. "He's been off so much lately that I'm afraid he'll get it inter his head it must be done reg'lar, whether he's got any business or not." "I'll look after him all right, so you needn't worry, Uncle Zenas," the keeper cried cheerily, and then the dory was pushed off from the shore, the cook and Sidney watching her until she had rounded the ledge, heading a straight course for the shore. "Now I reckon we'll go inter the lantern," Uncle Zenas said when it was no longer possible to distinguish the faces of those in the boat, owing to the dim light. "Cap'n Eph will keep his eyes on the light, an' if it shouldn't happen to die away at the very minute when the sun ought'er rise 'cordin' to his watch, the chances are he'd make all hands come back to straighten us out." Nothing so serious as that took place, however, for the light was extinguished at the proper moment, and then the work of making it ready for another night was begun. "I declare for it, Sonny, you're as handy with this job as if you'd been at it all your life!" Uncle Zenas exclaimed while Sidney was working. "You're doin' it a heap better'n Sammy ever can, even if he sticks on this ledge to the day of his death." "That is because I've been trying hard to find out just how it should be done," Sidney said laughingly, but decidedly pleased by the words of praise. "You've all been so good to me, that I'd be a pretty poor kind of a boy if I didn't do my best at the little jobs that come my way." "It may seem as if you was gettin' the best end of the trade, Sonny; but you're way off mistaken. We old shell-backs are the ones who's havin' all the fat, 'cause it brightens us up wonderfully to have you 'round." Sidney was at a loss for a reply to this remark, and changed the subject of the conversation by asking Uncle Zenas of what service a certain cylinder of thin brass, which entirely encircled the chimney of the lamp, could be in the general arrangement of the light.
