At forty-seven minutes past twelve they reached the buoy; it was in perfect condition, and must have shifted but little.
“At last!” exclaimed J. T. Maston.
“Shall we begin?” asked Captain Blomsberry.
“Without losing a second.”
Every precaution was taken to keep the corvette almost completely motionless. Before trying to seize the projectile, Engineer Murchison wanted to find its exact position at the bottom of the ocean. The submarine apparatus destined for this expedition was supplied with air. The working of these engines was not without danger, for at 20,000 feet below the surface of the water, and under such great pressure, they were exposed to fracture, the consequences of which would be dreadful.
J. T. Maston, the brothers Blomsberry, and Engineer Murchison, without heeding these dangers, took their places in the air-chamber. The commander, posted on his bridge, superintended the operation, ready to stop or haul in the chains on the slightest signal. The screw had been shipped, and the whole power of the machinery collected on the capstan would have quickly drawn the apparatus on board. The descent began at twenty-five minutes past one at night, and the chamber, drawn under by the reservoirs full of water, disappeared from the surface of the ocean.
The emotion of the officers and sailors on board was now divided between the prisoners in the projectile and the prisoners in the submarine apparatus. As to the latter, they forgot themselves, and, glued to the windows of the scuttles, attentively watched the liquid mass through which they were passing.
The descent was rapid. At seventeen minutes past two, J. T. Maston and his companions had reached the bottom of the Pacific; but they saw nothing but an arid desert, no longer animated by either fauna or flora. By the light of their lamps, furnished with powerful reflectors, they could see the dark beds of the ocean for a considerable extent of view, but the projectile was nowhere to be seen.
The impatience of these bold divers cannot be described, and having an electrical communication with the corvette, they made a signal already agreed upon, and for the space of a mile the Susquehanna moved their chamber along some yards above the bottom.
Thus they explored the whole submarine plain, deceived at every turn by optical illusions which almost broke their hearts. Here a rock, there a projection from the ground, seemed to be the much-sought-for projectile; but their mistake was soon discovered, and then they were in despair.
