San Francisco Bay is so large that often its storms are more disastrous to ocean-going craft than is the ocean itself in its violent moments. The waters of the bay contain all manner of fish, wherefore its surface is ploughed by the keels of all manner of fishing boats manned by all manner of fishermen. To protect the fish from this motley floating population many wise laws have been passed, and there is a fish patrol to see that these laws are enforced. Exciting times are the lot of the fish patrol: in its history more than one dead patrolman has marked defeat, and more often dead fishermen across their illegal nets have marked success.

Wildest among the fisher-folk may be accounted the Chinese shrimp- catchers. It is the habit of the shrimp to crawl along the bottom in vast armies till it reaches fresh water, when it turns about and crawls back again to the salt. And where the tide ebbs and flows, the Chinese sink great bag-nets to the bottom, with gaping mouths, into which the shrimp crawls and from which it is transferred to the boiling-pot. This in itself would not be bad, were it not for the small mesh of the nets, so small that the tiniest fishes, little new-hatched things not a quarter of an inch long, cannot pass through. The beautiful beaches of Points Pedro and Pablo, where are the shrimp-catchers' villages, are made fearful by the stench from myriads of decaying fish, and against this wasteful destruction it has ever been the duty of the fish patrol to act.

When I was a youngster of sixteen, a good sloop-sailor and all- round bay-waterman, my sloop, the Reindeer, was chartered by the Fish Commission, and I became for the time being a deputy patrolman. After a deal of work among the Greek fishermen of the Upper Bay and rivers, where knives flashed at the beginning of trouble and men permitted themselves to be made prisoners only after a revolver was thrust in their faces, we hailed with delight an expedition to the Lower Bay against the Chinese shrimp-catchers.

There were six of us, in two boats, and to avoid suspicion we ran down after dark and dropped anchor under a projecting bluff of land known asPoint Pinole. As the east paled with the first light of dawn we got under way again, and hauled close on the land breeze as we slanted across the bay toward Point Pedro. The morning mists curled and clung to the water so that we could see nothing, but we busied ourselves driving the chill from our bodies with hot coffee. Also we had to devote ourselves to the miserable task of bailing, for in some incomprehensible way the Reindeer had sprung a generous leak. Half the night had been spent in overhauling the ballast and exploring the seams, but the labor had been without avail. The water still poured in, and perforce we doubled up in the cockpit and tossed it out again.

After coffee, three of the men withdrew to the other boat, a Columbia River salmon boat, leaving three of us in the Reindeer. Then the two craft proceeded in company till the sun showed over the eastern sky-line. Its fiery rays dispelled the clinging vapors, and there, before our eyes, like a picture, lay the shrimp fleet, spread out in a great half-moon, the tips of the crescent fully three miles apart, and each junk moored fast to the buoy of a shrimp-net. But there was no stir, no sign of life. The situation dawned upon us. While waiting for slack water, in which to lift their heavy nets from the bed of the bay, the Chinese had all gone to sleep below. We were elated, and our plan of battle was swiftly formed.

"Throw each of your two men on to a junk," whispered Le Grant to me from the salmon boat. "And you make fast to a third yourself. We'll do the same, and there's no reason in the world why we shouldn't capture six junks at the least."Then we separated. I put the Reindeer about on the other tack, ran up under the lee of a junk, shivered the mainsail into the wind and lost headway, and forged past the stern of the junk so slowly and so near that one of the patrolmen stepped lightly aboard. Then I kept off, filled the mainsail, and bore away for a second junk.

Up to this time there had been no noise, but from the first junk captured by the salmon boat an uproar now broke forth. There was shrill Oriental yelling, a pistol shot, and more yelling.

"It's all up. They're warning the others," said George, the remaining patrolman, as he stood beside me in the cockpit.

By this time we were in the thick of the fleet, and the alarm was spreading with incredible swiftness. The decks were beginning to swarm with half-awakened and half-naked Chinese. Cries and yells of warning and anger were flying over the quiet water, and somewhere a conch shell was being blown with great success. To the right of us I saw the captain of a junk chop away his mooring line with an axe and spring to help his crew at the hoisting of the huge, outlandish lug-sail. But to the left the first heads were popping up from below on another junk, and I rounded up the Reindeer alongside long enough for George to spring aboard.

The whole fleet was now under way. In addition to the sails they had gotten out long sweeps, and the bay was being ploughed in every direction by the fleeing junks. I was now alone in the Reindeer, seeking feverishly to capture a third prize. The first junk I took after was a clean miss, for it trimmed its sheets and shot away surprisingly into the wind. By fully half a point it outpointed the Reindeer, and I began to feel respect for the clumsy craft. Realizing the hopelessness of the pursuit, I filled away, threw out the main-sheet, and drove down before the wind upon the junks to leeward, where I had them at a disadvantage.
