Martin thought for a minute, looking interestedly at the submarine as they trundled past. ''Ow does men jine 'em?' he asked eventually.

''Ow does they qualify for 'em, d'you mean?' Hawkins queried.

Martin nodded.

'Well,' his neighbour explained, with a broad grin on his face, and inventing a still broader fiction on the spur of the moment, 'they fu'st ties a five-'underweight sinker to yer feet an' a rope round yer neck. Then they lowers you down to nineteen fathom, an' leaves you there for two minutes.—Let's see, Shorty,' he added, pretending to consider, and, turning to another ordinary seaman with a solemn wink, 'is it two minutes or three minutes they leaves yer down?'

'Three minutes, chum,' answered the other unblushingly.

'Well, they leaves you down three minutes, an' they pulls you up again, an' if yer nose ain't bleedin' they reckons as 'ow you're fit an' proper for submarines. If you are bleedin' you ain't no good—see?'

'That's a bit 'ard, ain't it?' Martin queried innocently.

'Yus, it is a bit 'ard,' Hawkins replied, without a smile on his face. 'But then, o' course, the men wot man the submarines 'as to be extra special sort o' blokes wot 'as got plenty o' guts.'

Martin drank it all in; but at that moment the story-teller's face failed him, and he burst into uncontrollable laughter. 'Oh Pincher!' he gasped, spluttering, 'I believes you'd swaller anythink any one tells yer!'

'D' you mean that wot you said ain't true?' Martin asked.
