Into one of these crowding holes the diver crawled. There was the tedious work of tearing off the casing to occupy an hour or more, and when it was accomplished he endeavored to back out of his situation. He was stopped fast and tight in his regression. The arrangement of the armor about the head and shoulders, making a cone whose apex was the helmet, prevented his exit. It was like the barb of a harpoon, and caught him fast in the wood. Such a danger is not sudden in its revelation. There is at first only a feeling of impatience at the embarrassment, a disposition to "tear things." In vain attempts at doubling and other gymnastic feats the diver wasted several hours, until his companions above became alarmed at the delay. They renewed and increased their labors at the force-pump, and the impetuous torrent came surging about the diver's ears. It served to complete his danger. It sprung the trap in which he lay enclosed. The inflated armor swelled and filled up the crowded spaces. It stiffened out the casing of the helmet to equal the burden of fifty pounds to the square inch, and made it as hard as iron. He was caught like the gluttonous fox. The bulky volume of included air made exit impossible. It was no longer a labyrinth as before, where freedom of motion incited courage: he was in the fetters of wind and water, bound fast to the floor of his dungeon den. He signaled for the pump to stop. It was the only alternative. He might die without that life-giving air, but he would certainly die if its volume was not reduced. The cock at the back of the helmet for discharging the vessel was out of his reach. The invention never contemplated a case in which the diver would perish from the presence of air. As the armor worn was made tight at the sleeves with elastic wristbands, his remedy was to insert his fingers under it, and slowly and tediously allow the bubbling air to escape. In this he persevered steadily, encouraged by the prospect of escape. The way was long and difficult, but release certain with the reduction of that huge bulk. But a new and subtler danger attacked him--the very wit of Nature brought to bear upon his force and ingenuity. It was as if the mysterious sirens of the sea saw in that intellectual force the real strength of their prisoner, and sought to steal it from him while they lulled him to indifference. Inhaling and reinhaling the reduced volume of air, it became carbonized and foul, not with the warning of sudden oppression, but Sly as April melts to May, And May slips into June. The senses, intoxicated by the new companion sent them by the lungs, began to sport with it, as ignorant children with a loaded shell, forgetful of duty and the critical condition of the man. They began to wander in vagaries and delusions. A soft chime of distant bells rang in his ears with the sweet sleepy service of a Sabbath afternoon; the sound of hymns and the organ mingled with the melody and the chant of the sirens of the sea.
