"We'd rather remain up, if you don't mind," said Leslie, remembering the hard bunk in the little cabin. Besides, it was the novelty of seeing the trawls, laden with glittering fish, being hauled on board, that was one of the objects of his trip.

"All right," replied Runswick, good-humouredly. "No doubt we can make you properly useful." Acting upon the skipper's advice, the two lads turned in for a few hours on the understanding that they would be called directly the nets were ready to be shot.

Contrary to their expectations, they slept like logs until one in the morning, when Peter, knocking loudly at the cabin door, announced that all was in readiness.

Putting on thick sweaters, Leslie and Guy went on deck. It was pitch dark, except for the feeble glimmer of two lanterns hung vertically from the forestay. Not a star was visible. There was hardly any wind, while the sea was calm and strangely phosphorescent.

Slowly Long Garge and Peter, assisted by the two "supernumeraries," paid out yard after yard of carefully coiled nets, for the speed at which the Laughing Lassie was moving was so slight that any attempt to shoot the nets hurriedly would result in a disastrous tangle.

"All out, Cap'n!" announced Long Garge, as the last of the cork floats disappeared overboard. "But, blow me, if there ain't thick weather a-comin' on."

In a very short space of time the deck of the Laughing Lassie was hidden in a pall of vapour. It was impossible to see the regulation lights from the after-part of the ketch.

"'Tis thick," agreed Skipper Runswick. "Peter, you nip below and get out the fog-horn. It'll keep you busy. Thank goodness we're out of the regular steamer tracks," he added under his breath.

Although the night had hitherto been warm and humid, a cold clamminess accompanied the fog. In spite of their thick sweaters, the lads shivered.

"Nothin' doin' for a bit," said the skipper, almost colliding with his guests, as he made his way for'ard. "Go below to the cabin. Unless the fog lifts pretty soon, we'll not get the nets in afore dawn. If you're still of a mind to see the job being done, I'll give you the word."
