es opposite. They've got a quick-firer. Are you game to hunt 'em
down?'

'Kemp?' exclaimed Roy, who had of course heard the story of the treachery
aboard the 'Cardigan Castle.' 'Kemp, that spy scoundrel--are you sure?'

'Dead certain, though I can't imagine how he got here.'

'More can I, but by the Lord Harry, we'll have his scalp all right. Which
way did they go?'

Ken pointed and began to run. Roy raced alongside.

It was the maddest enterprise, and if either had stopped to think they
would have realised this fact. Two against four, and the latter armed with
a quick-firer! And by way of improving matters, the two had outrun all
their companions and were far out in a country swarming with enemy troops.

But Ken thought only of vengeance against the traitor Kemp, and as for
Roy, he was the sort to fight till he dropped, and laugh at any odds.

'Where's Dave?' asked Ken, as they tore along, side by side.

'All right when I last saw him about half a mile back,' was the answer.
'Which way have those blighters gone?'

Ken, alone, might have been at a loss to follow, but this was where Roy
came in. Brought up on a great cattle run, he could track a stray beast
over miles of ranges. It was child's play to him to trace the heavy
footmarks over the leaf-strewn floor of the wood.

'Go as quietly as you can,' he whispered to Ken. 'Kemp's quite cute enough
to ambush us if he thinks we're on his track.'

It was wonderful how quietly the young giant could move, and Ken,
naturally light-footed, followed his example easily. The tracks led
uphill, and presently the trees began to thin, and the ground to become
more stony.

Then the trees gave out altogether, and they found themselves on the side
of a great hill seamed with gullies and covered with low scrub and loose
stones.

'There they are!' said Ken in a low voice, pointing to heads just visible
over the edge of one of the shallow gullies. 'I tell you what they're
after. They're going to emplace that gun somewhere up on the hill-side,
and pepper our people on their way back.'

Roy nodded.

'That's about the size of it. Well, it's up to us to spoil their little
game. We must work up along the next gully parallel with them and get a
slap at 'em over the edge.'

'That's the tip,' said Ken, 'but mind, we've got to bust
