Fire gutted a second not long after, so that for weeks she was laid up for repairs. That left him but two efficient craft. One operated on his concessions along the mainland shore. The other worked three stream mouths on Vancouver Island, straight across from Folly Bay.

Still, Gower's cannery was getting salmon. In those three bays no other purse seiner could shoot his gear. Folly Bay held them under exclusive license. Gill nets could be drifted there, but the purse seiner was king.

A gill net goes out over a boat's stern. When it is strung it stands in the sea like a tennis net across a court, a web nine hundred feet long, twenty feet deep, its upper edge held afloat by corks, its lower sunk by lead weights spaced close together. The outer end is buoyed to a float which carries a flag and a lantern; the inner is fast to the bitts of the launch. Thus set, and set in the evening, since salmon can only be taken by the gills in the dark, fisherman, launch, and net drift with the changing tides till dawn. Then he hauls. He may have ten salmon, or a hundred, or treble that. He may have none, and the web be torn by sharks and fouled heavy with worthless dogfish.

The purse seiner works in daylight, off a powerfully engined sixty-foot, thirty-ton craft. He pays the seine out over a roller on a revolving platform aft. His vessel moves slowly in a sweeping circle as the net goes out,—a circle perhaps a thousand feet in diameter. When the circle is complete the two ends of the net meet at the seiner's stern. A power winch hauls on ropes and the net closes. Nothing escapes. It draws together until it is a bag, a "purse" drawn up under the vessel's counter, full of glistening fish.

The salmon is a surface fish, his average depth seldom below four fathoms. He breaks water when he feeds, when he plays, when he runs in schools. The purse seiner watches the signs. When the salmon rise in numbers he makes a set. To shoot the gear and purse the seine is a matter of minutes. A thousand salmon at a haul is nothing. Three thousand is common. Five thousand is far below the record. Purse seines have been burst by the dead weight of fish against the pull of the winch.

The purse seine is a deadly trap for schooling salmon. And because the salmon schools in mass formation, crowding nose to tail and side to side, in the entrance to a fresh-water stream, the Fisheries Department having granted a monopoly of seining rights to a packer has also benevolently decreed that no purse seine or other net shall operate within a given distance of a stream mouth,—that the salmon, having won to fresh water, shall go free and his kind be saved from utter extinction.

These regulations are not drawn for sentimental reasons, only to preserve the salmon industry. The farmer saves wheat for his next year's seeding, instead of selling the last bushel to the millers. No man willfully kills the goose that lays him golden eggs. But the salmon hunter, eagerly pursuing the nimble dollar, sometimes grows rapacious in the chase and breaks laws of his own devising,—if a big haul promises and no Fisheries Inspector is by to restrain him. The cannery purse seiners are the most frequent offenders. They can make their haul quickly in forbidden waters and get away. Folly Bay, shrewdly paying its seine crews a bonus per fish on top of wages, had always been notorious for crowding the law.

Solomon River takes its rise in the mountainous backbone of Vancouver Island. It is a wide, placid stream on its lower reaches, flowing through low, timbered regions, emptying into the Gulf in a half-moon bay called the Jew's Mouth, which is a perfect shelter from the Gulf storms and the only such shelter in thirty miles of bouldery shore line. The beach runs northwest and southeast, bleak and open, undented. In all that stretch there is no point from behind which a Fisheries Patrol launch could steal unexpectedly into the Jew's Mouth.

Upon a certain afternoon the Blackbird lay therein. At her stern, fast by light lines to her after bitts, clung half a dozen fish boats, blue wisps of smoke drifting from the galley stovepipes, the fishermen variously occupied. The Blackbird's hold was empty except for ice. She was waiting for fish, and the Bluebird was due on the same errand the following day.
