"Be careful there, Smith," warned Madden in an undertone; "he'd as soon as not slug you without giving you a dog's chance."

Caradoc said nothing but continued his climbing. The men on the platform fore and aft ceased work, watching the mate and the climbing man intently. The silence following the usual drone of conversation was noticeable.

Caradoc was just reaching up to climb into Malone, when at that moment something happened that drew and held everybody's attention.

The whole face of the sea around the dock broke into a sort of sputtering. The ocean seemed to boil. To his astonishment, Madden saw the commotion was caused by millions of small fishes leaping and running along the surface.

Cries came from all over the dock at once: "Pilchards! Pilchards are shoaling! Pilchards are shoaling!"

The few gulls in the sky now seemed to multiply and settled in a fluttering cloud to strike such easily captured food. Among the press of little fish leaped cod, hake, dog fish, all feasting on the annual migration of the pilchards. The crew on the dock scrambled up and over the sides, flung down boxes, buckets, anything and scooped the fish from the sea.

The diversion saved the Englishman from any bellicose intention of the mate, who hurried off to take a hand in the sport. Madden sat on his platform watching the fun, for it was a remarkable sight. Caradoc swung around on the ladder facing Leonard.

"There, Madden," he cried, "is a sight characteristic of no other sea. Every season Cornish fisheries capture millions of these fish. They pickle 'em, can 'em. They even sell them to you Yankees for sardines. You are fortunate to have seen this phenomenon."

Leonard studied the novel sight. Hundreds of fishing smacks converged on the area where the pilchards were breaking, their red sails glowing warmly against the green of the land and the blue of the sea. Gulls whirled about the tall dock, filling the air with thin creakings. Madden admired the sudden picturesque activity. Some of the smacks were so close now that he could see their long trawls stringing out behind, and little figures running about their decks, winding in nets, bringing in a flood of silver fishes.

The metallic noise of the gulls grew so loud as to blanket all else. In the midst of this fluttering and shrieking, Leonard heard the shouting of human voices. He paid little attention. Then some of the men on top of the dock's side began yelling. At that moment, Caradoc shouted down Madden's name. Madden looked up. On the instant the swinging platform under him tipped violently.
