The whole of the cable remaining on board has been carefully tested and inspected, and found to be in as perfect condition as when it left the works at Greenwich and Birkenhead respectively.
One important point presses for your consideration at{73} an early period. A large portion of cable already laid may be recovered at a comparatively small expense. I append an estimate of the cost, and shall be glad to receive your authority to proceed with this work.
I do not perceive in our present position any reason for discouragement; but I have, on the contrary, a greater confidence than ever in the undertaking.
It has been proved beyond a doubt that no obstacle exists to prevent our ultimate success; and I see clearly how every difficulty which has presented itself in this voyage can be effectually dealt with in the next.
The cable has been laid at the expected rate in the great depths; its electric working through the entire length has been satisfactorily accomplished, while the portion laid, actually improved in efficiency by being submerged—from the low temperature of the water and the increased close texture of gutta-percha thereby effected.
Mechanically speaking, the structure of the cable has answered every expectation that I had formed of it. Its weight in water is so adjusted to the depth that strain is within a manageable scope; while the effects of the undercurrents upon its surface prove how dangerous it would be to lay a much lighter rope, which would, by the greater time occupied in sinking, expose an increased surface to their power, besides its descent being at an angle such as would not provide for good laying at the bottom.
On the other hand, in regard to any further length made, I would take this opportunity of again strongly urging the desirability of a much larger conductor and corresponding increase in the weight of insulation, in accordance with my original recommendation.—I have the honor to remain, gentlemen, yours very faithfully,
Charles T. Bright,
Engineer-in-Chief.
