'The skipper says he hasn't any keys, sir,' a sailor called down. 'We have searched him, and can't find any, sir.'

'Very well, then,' the officer said; 'we must do without them. Force open that cupboard.'

One of the two sailors pulled out his knife and forced the lock with little difficulty; then he slid back the shutter and displayed the coper's stock of spirits, wines, tobacco, and cigars.

'A very nice collection indeed,' the revenue officer declared. 'I am very much obliged to you for your assistance,' he continued, addressing Charlie; 'but I must ask you to explain why you are on board this boat. You are my prisoner, although you do not appear to be in league with the skipper.'

Charlie related all that had happened to him. The story of his and Ping Wang's adventures amused the revenue officer highly.

'Well,' he said, at the end of the story, 'I'm very glad to have met both of you. After I have had a peep in the hold, I will take you aboard my cutter.'

The hold, with its stock of nets and other stolen property, added to the revenue officer's satisfaction at the capture he had made. Leaving five men on the coper, to man it—three on deck and two in the saloon—he returned to his cutter, taking Charlie and Ping Wang with him. As soon as they were aboard, the cutter started, escorting the coper into Grimsby.

'How did you manage to catch the coper?' Charlie asked the lieutenant, as they were watching the land coming nearer and nearer.

'I discovered her yesterday, but could not get close to her while she was in British waters. I saw that the chances of catching her were against me, so did not make the attempt. At night I went out to sea with covered lights, and kept my eye on her. Just before daybreak she went back into British waters, and I followed her. When there was light enough for her to see me, she fancied, as I intended she should, that I was a fishing-boat returning to Grimsby. While she had two trawlers' boats alongside I made for her. Then she guessed who I was, and tried to escape, but when I sent a shot across her bows she lay to, and the skipper demanded to know what I meant. I soon told him.'

'I fancy,' Charlie said, 'that the coper skipper is an old hand at the game.'
