Raising Further Capital.—To make the above sum good, the capital of the company had to be increased, and this new capital was not so readily obtainable. The projectors found that it was easy to go with the current of popular enthusiasm, but very hard to stem a growing tide of popular distrust. And it must also be remembered that, from the very first, the section of the public which looked with distrust upon the idea of an Atlantic telegraph was far in excess of that which did not; indeed, the opposition encountered was much on a par with{76} the great popular prejudice which George Stephenson had to overcome when projecting his great railway schemes. But whatever the depression at the untimely termination of the first expedition, it did not interfere with renewed and vigorous efforts to prepare for a second. In the end the appeal to the shareholders for more money was responded to; and the directors were enabled to give orders for the manufacture of 700 miles of new cable of the same description, to make up for what had been lost, and to provide a surplus against all contingencies. Thus, 3,000 nautical miles in all were shipped this time, instead of 2,500 miles.
Alterations in the Paying-Out Gear.—New paying-out machinery was devised with a view to obviating the possibility of a recurrence of the accident on the first expedition. In the new apparatus the brake (Fig. 16) was so arranged that a lever exercised a uniform holding power in exact proportion to the weights attached to it (Fig. 17); and while capable of being released by a hand-wheel, it could not be tightened. The general idea of this clever appliance had been originally introduced by Mr. J. G. Appold in connection with the crank apparatus in jails; and it was now especially adapted to the exigencies of cable work by the engineer (Mr. Bright) and Mr. C. E. Amos, a member of the famous engineering firm, Easton & Amos, who constructed the entire machinery. The great future of the apparatus was that it provided for automatic brake-release, upon the strain exceeding that intended. Thus, only a maximum agreed strain could be applied, this being regulated from time to time by weights, according{77} to the depth of water and consequent weight of cable being paid out. In passing from the hold to the stern of the laying vessel, the cable is taken round a drum, or drums. Fig. 18 gives a general view of the apparatus. Attached to the axle of the drum is a wheel fitted with an iron friction-strap (to which are fixed blocks of hard wood) capable of exerting a given retarding power, varying with the weights hung on to the lever which tightens the strap. When the friction becomes great, the wheels have an increased tendency to carry the wooden blocks round with them; thus the lever-bars are deflected from the vertical line and the iron band opened sufficiently to lessen the brake-power.
