et not be seen on the main land.

At eleven o'clock the first rays of the full moon became visible from
behind Mount Tarrengower. The night was awful quiet, and not a living
thing had approached us, and not a sound had we heard, except an
occasional bleat of a lamb, off towards the stock-house on our left.

"Let us be moving for the island," Mr. Brown said, almost in a whisper,
for the solemnity of the scene was bringing back all his superstitions
and fears.

I readily consented, and, lighting our pipes, we walked slowly towards
the peninsula, crossed it, and then waited calmly for the shadow which
the mountain was to throw upon the spot of earth where the robber's
treasure was buried. Our pickaxe and shovel remained where we had left
them, although I could not help fancying that they had been handled
since I had thrown them down. I said nothing to my friend on the
subject, however, for he was too full of imaginative fancies to be
consulted and listened to.

Time passed slowly while we sat and watched the shadow which was
creeping over the bogs, as the moon rose behind the mountain. I
consulted my watch and found that it was nearly twelve, but just at that
moment a white cloud passed over the moon, and our hopes seemed dashed.
The shadow was no longer to be seen; we watched that white cloud as
though our lives depended upon its disappearing, but still it lingered,
like a veil covering the face of a coquette--anxious, to reveal the
beauty which was concealed, yet taking pleasure in exciting expectation.

"What time is it?" whispered Mr. Brown.

I held my watch before him, while I again scanned the heavens.

"It is just twelve o'clock," my companion whispered.

Hardly had the words escaped his lips, before the cloud disappeared, and
the moon looked down with a roguish twinkle. We started to our feet,
when, lo! precisely where we stood was the edge of the shadow, cast in
the form of a cross, with the upper part resting towards us.

Mr. Brown seized the pickaxe and struck it into the ground, and as he
did so I thought that I heard a low groan. I could not tell in what
direction it came from, yet I would have sworn that it originated on the
island. I glanced at the face of my companion, but he was too intent
upon the business before him to notice my look, or to pay any attention
to the sound that had disturbed my composure.

"There is one thing I wish to caution you about," my companion said,
pausing in his work;
