Early on the morning of the 4th, the lads were roused from their slumbers by a roar of cheering. Emerging from their shell-proof shelter, they were surprised and delighted to find that rumour had merged into fact. Surging along towards the trenches in the direction of Lierre were hundreds of men dressed in the well-known British naval uniform. As yet they were not under shellfire, for the German guns were devoting their energies towards the works at Lierre, and the hostile air-craft had not noted the approach of British reinforcements.

Presently the bluejackets halted and piled arms. It was their last breathing-space before they dashed into the shell-swept trenches.

"Let's go and see them," suggested Rollo; and his companion agreeing, the two chums hurried towards the resting bluejackets, who were surrounded by hundreds of their Belgian allies, for the present off duty from the firing-line.

"I wonder how we manage to spare this crowd of sailors," remarked Kenneth as they made their way towards their fellow-countrymen. "I should have thought that every man would be wanted for service with the fleet."

"At any rate, they're here," said Rollo; "and there are fellows in khaki coming along the Lierre road, if I'm not much mistaken."

The lads stood watching the sailors for some time. Their insular reserve kept them from immediately entering into conversation, although they were filled with impatience to know what had happened.

For the most part the bluejackets were young men of good physique. They lacked the bronzed appearance of seamen who have braved the breezes of the five oceans. Many of them were pale, not with apprehension, but with a consciousness that they had before them a stern task that would tax their energies and courage, for they were going under fire for the first time.

Presently one of the bluejackets strolled up to the spot where Kenneth and his chum were standing.

"Est-ce—est-ce que vous—oh, hang it! what's the French for——" he began.

"Try English, old man; it will be a jolly sight easier for you," said Kenneth, laughing.
