A PRELIMINARY SURVEY

Gilliatt was pressed on all sides by demands upon his labours. The most pressing, however, was to find a safe mooring for the barge; then a shelter for himself.

The Durande having settled down more on the larboard than on the starboard side, the right paddle-box was higher than the left.

Gilliatt ascended the paddle-box on the right. From that position, although the gut of rocks stretching in abrupt angles behind the Douvres had several elbows, he was able to study the ground-plan of the group.

This survey was the preliminary step of his operations.

The Douvres, as we have already described them, were like two high gable-ends, forming the narrow entrance to a straggling alley of small cliffs with perpendicular faces. It is not rare to find in primitive submarine formations these singular kinds of passages, which seem cut out with a hatchet.

This defile was extremely tortuous, and was never without water even in the low tides. A current, much agitated, traversed it at all times from end to end. The sharpness of its turnings was favourable or unfavourable, according to the nature of the prevailing wind; sometimes it broke the swell and caused it to fall; sometimes it exasperated it. This latter effect was the most frequent. An obstacle arouses the anger of the sea, and pushes it to excesses. The foam is the exaggeration of the waves.

The stormy winds in these narrow and tortuous passages between the rocks are subjected to a similar compression, and acquire the same malignant character. The tempest frets in its sudden imprisonment. Its bulk is still immense, but sharpened and contracted; and it strikes with the massiveness of a huge club and the keenness of an arrow. It pierces even while it strikes down. It is a hurricane contracted, like the draught through the crevice of a door.

The two chains of rocks, leaving between them this kind of street in the sea, formed stages at a lower level than the Douvres, gradually decreasing, until they sunk together at a certain distance beneath the waves.

There was another such gullet of less height than the gullet of the Douvres, but narrower still, and which formed the eastern entrance of the defile. It was evident that the double prolongation of the ridge of rocks continued the kind of street under the water as far as “The Man Rock,” which stood like a square citadel at the extremity of the group.
