“Hi, ‘Gyp,’ rats!” shouted the captain, when we all came up to a pile of old casks and sails in the fore peak. “Go for ’em, good dog!”

The wardroom steward and the captain’s valet had come down in the rear of the officers, each of them provided with a lantern; and so, what with the lights we already had with us, the place was sufficiently illuminated for all to see the whole proceedings, which, needless to say, we witnessed with the utmost delight, Mick, who was alongside of me, staring open-mouthed, his face one broad grin from ear to ear.

“Begorrah!” he whispered to me. “Sure, it bates Bannagher, an’s a’most as good as what Oi’ve heerd tell of Donnybrook Fair, in the ould toimes, from me fayther!”

All we could see of ‘Gyp’ for some little time was a portion of his stern quarters, with his little butt-end of a tail wagging away at high-pressure speed, just like the escapement of a clock from which the pendulum has been temporarily taken, so that it has for the moment no check on its action.

Then, all at once, with a low growl, and every individual hair on his white coat standing erect, his whole body the while quivering with excitement, ‘Gyp’ plunged forwards and disappeared into darkness, only to reappear an instant later with an enormous rat, which he had gripped in the small of the back, the vicious beast trying to worm itself round so as to tackle his nose.

‘Gyp,’ however, knew a trick worth two of that, and, as he emerged into the open again, chucked the rat up aloft in the air, almost to the deck beams, and then, pouncing on it as the brute fell back under his expectant jaws, the terrier severed its head from its body with one snap!

Another and another, and yet another, he served in like fashion, ferreting in amongst the dunnage, and then coming out again with a fresh victim each time; until, presently, finding their retreat ‘too warm’ for them, the rats sallied out in a crowd, skating over the deck and climbing up the bulkheads to get out of the way of their relentless enemy. The lot of us then coming to the aid of ‘Gyp,’ the captain and all catching up anything handy to have a shy at them, the family of rodents that had been having such a gay old time below for so long without interference, was soon exterminated; after which the dog and his master, with the other officers, returned to the main-deck, while we resumed our work at the pumps all the more heartily from the bit of play we had had, old Jellybelly never once grumbling again till we had done.

We had a good rise out of the old quarter-master the very same evening, though, which was rather ill-natured on our part.

He was on duty at the gangway, when one of the new chaps, who, like Larrikins, had a great bent for practical skylarking, went to him with a smug face, as innocent as you please.

“I say, sir,” said he, in a tone of the deepest sympathy, “don’t you feel werry tired, sir, a-standing theer so long?”
