At that depth the light was strong enough to see nearly twenty yards ahead, and Hythe was struck with the peculiar formation of the submarine gorge. It was as if human hands had hewn out a deep and narrow passage through the solid rock, here and there cutting side tunnels that faded away in the distant gloom. Fantastic marine growths occurred in patches that had to be carefully avoided, for some of the tendrils were armed with crooked spikes, sufficiently strong and sharp to do untold damage to any diver who was incautious enough to get into their toils. At other places fern-like weeds growing to a height of ten feet made the floor of the bay resemble a tropical-forest. Sponges grew in profusion; oyster-shells, a yard in diameter, were occasionally met with. Once O’Shaunessey’s foot narrowly escaped being seized by the gaping jaws of one of these bivalves. A second later and his limb would have been crushed to a pulp.
As the five advanced crabs large and small swarmed sideways across their path to seek shelter amongst the rocks; fish in shoals darted from the unwonted sight of the diving-dresses, although a few, bolder or more stupid than the rest, swam quite close to the submarine pedestrians.
Presently the passage bifurcated, both arms shooting off at a very narrow angle. Unhesitatingly Captain Restronguet took the left. All the same Hythe wondered what would happen if they lost their way, for there was nothing whereby he could distinguish one way from another.
Stopping at one of the branch passages Captain Restronguet pointed towards it, then switching on his lamp began to clear away through the seaweed that grew to a height of nearly twenty feet. Hythe followed, tit was like pushing aside a Japanese curtain, for the flexible tendrils closed behind him.
The belt of weed was comparatively narrow; less than five yards brought the men to a close sandy space. Here the sub stopped. Right in front of him, and hidden from the natural light by a thick canopy of weeds, were the jagged, barnacle-encrusted timbers of a ship.
She was lying slightly over to starboard, but the list was enough to cause her double tier of guns to fall through the rotting planks. Her bowsprit had been carried away close to the gammoning; of her masts only two shattered stumps remained. Waterlogged cordage and sails trailed dolefully over her sloping deck, while her figurehead--that of a woman holding a rod--was just recognizable in its decay.
