"We catch plenty big fella mullet!" George exclaimed, as he gleefully splashed the water, and the cloud contracted and shrank back. The stream was about ten feet wide. Our equipment for sport consisted of a tomahawk and a grass-tree spear so frail that any of the mullet could have swum off with it without inconvenience. Straddling the stream side by side we splashed and "shooed" when the slightest symptom of a sally on the part of the fish was betrayed. A few brave leaders darted down, generally in pairs, and flashed back in fright at our noisy demonstrations, and so the blockade of the mullet began. While I stood guard shouting and "shooing" and making such commotion as I trusted would convince the fish that the blockading force was ever so much stronger and more truculent than it really was, George began to construct a pre-eminently practical wall. Its design was evolved ages upon ages ago by black students of hydrostatics and fish. George had imbibed the principles of its construction with his mother's milk. He cut down several saplings, and, screwing the butt ends into the soft sand about a foot apart, interlaced them with branches of mangrove and beach-trailers and swathes of grass. But the tide began to ebb. The pent-up current, strong and rapid, frequently carried portions of the structure away. George had to duck and dive to tie the vines and creepers to the stakes close down to the sandy bottom. Though armfuls of leafage floated to the surface and rolled out to sea, George worked with joyful desperation. Presently the fish began to make determined rushes. Shouting and splashing, tearing down branches, capturing driftwood, diving and gasping, his efforts were unceasing. Understanding the guile of the fish, he sought to make the deeper part of the weir secure, and for an hour or so he laboured in the water with head, hands, and feet. While with deft fingers he weaved creepers and branches to the stakes, his feet beat the surface into surf and surge to the scaring of the fish to the remote limits of their retreat. But the tighter the weir became, the more the pressure was on it. Fast as repairs were made at one spot gaps appeared in another which demanded immediate attention. The quantity of material that our works absorbed was scarcely to be realised. But a double-ended, amphibious black boy can work every-day wonders. Not a single fish had escaped. We had the whole shoal at our mercy, for George had confidently provided against all contingencies.
