That night, however, the expedition came to grief. The cable was running out freely at the rate of six miles per hour, while the ship was making only four. This was supposed to be owing to a powerful undercurrent. To check this waste of the cable the engineer applied the brakes firmly, which at once stopped the machine. The effect was to bring a heavy strain on the cable that was in the water. The stern of the ship was down in the trough of the sea, and as it rose upward on the swell, the pressure was too great, and the cable parted. The alarm was at once given, and the greatest consternation and grief prevailed on board. "It made all hands of us through the day," says Captain Hudson, "like a household or family which had lost their dearest friend, for officers and men had been deeply interested in the success of the enterprise." The fleet immediately put about and returned to England, where Mr. Field at once informed the directors of the extent of the disaster. The remaining portions of the cable were landed and stored safely away, and the vessels were returned to their respective Governments. Orders were given for the manufacture of seven hundred miles of cable to replace the portion which had been lost, and to allow for waste in paying it out, and the most energetic preparations were made for another attempt. Being satisfied that the machine used for paying out the cable was defective, Mr. Field went to Washington and procured from the Navy Department the services of Mr. Wm. E. Everett, the chief engineer of the "Niagara," stating to that gentleman the necessity for a new machine, and urging him to invent it. This Mr. Everett succeeded in doing during the winter. His machine was regarded as a great improvement on that which had been used on the "Niagara." "It was much smaller and lighter. It would take up only about one third as much room on the deck, and had only one fourth the weight of the old machine. Its construction was much more simple. Instead of four heavy wheels, it had but two, and these were made to revolve with ease, and without danger of sudden check, by the application of what were known as self-releasing brakes. These were the invention of Mr. Appold, of London, a gentleman of fortune, but with a strong taste for mechanics, which led him to spend his time and wealth in exercising his mechanical ingenuity. These brakes were so adjusted as to bear only a certain strain, when they released themselves. This ingenious contrivance was applied by Mr. Everett to the paying-out machinery. The strength of the cable was such that it would not break except under a pressure of a little over three tons. The machinery was so adjusted that not more than half that strain could possibly come upon the cable, when the brakes would relax their grasp, the wheels revolve easily, and the cable run out into the sea 'at its own sweet will.' The paying-out machine, therefore, we are far from claiming as wholly an American invention.
