passing. Such was now the case with the reef over which the ship had
beaten, the position of which could hardly have been ascertained, or its
danger discovered, at the distance of half a mile. Others again were of
a very different character, the water still tumbling about them like so
many little cataracts. This variety was owing to the greater depth at
which some of the rocks lay than others.

As to the number of the reefs, and the difficulty in getting through
them, Bob was right enough. It often happens that there is an inner and
an outer reef to the islands of the Pacific, particularly to those of
coral formation; but Mark began to doubt whether there was any coral at
all in the place where the Rancocus lay, in consequence of the entire
want of regularity in the position of these very breakers. They were
visible in all directions; not in continuous lines, but in detached
parts; one lying within another, as Bob had expressed it, until the eye
could not reach their outer limits. How the ship had got so completely
involved within their dangerous embraces, without going to pieces on a
dozen of the reefs, was to him matter of wonder; though it sometimes
happens at sea, that dangers are thus safely passed in darkness and fog,
that no man would be bold enough to encounter in broad daylight, and
with a full consciousness of their hazards. Such then had been the sort
of miracle by which the Rancocus had escaped; though it was no more easy
to see how she was to be got out of her present position, than it was to
see how she had got into it. Bob was the first to make a remark on this
particular part of the subject.

"It will need a reg'lar branch here, Mr. Mark, to carry the old Rancocus
clear of all them breakers to sea again," he cried. "Our Delaware banks
is just so many fools to 'em, sir!"
