In the laying of light and power cables every joint, as made, should be tested for insulation with a Thomson galvanometer, as the insulation must necessarily be very high, and if one joint or section of cable is any weaker than another it may be very important in the future to know it. All tests must be made after the joint has cooled, for while hot its insulation resistance will be very low.
The wilderness waterways on both sides soon saw the strange spectacle of immense anchors, cables, cannon, and ship tackle of all kinds, as well as armies of sailors, shipwrights, and riggers, making their way to the new rival bases at Sackett's Harbor and Kingston, both near the foot of Lake Ontario. Of the whole lake and river frontier, Ontario was of the most vital importance.
The hatches of the hold were all opened yesterday evening, and we began to make the cables fast to the anchors, which we finished this morning. As soon as the sun rose, every one climbed aloft in order to look for land and some of them immediately cried out "land," but they soon discovered they were mistaken.
The first mate went forward, and he and Pengarvan saw the anchors got in readiness, and the cables ranged along, so as to run out with perfect freedom. Then Pengarvan made his way aft again to the poop. "Do you mean to cut away the mast, Captain?" The captain nodded. "I wouldn't, sir," the mate went on.
A great many ships having been wrecked, inasmuch as the rest, having lost their cables, anchors, and other tackling, were unfit for sailing, a great confusion, as would necessarily happen, arose throughout the army; for there were no other ships in which they could be conveyed back, and all things which are of service in repairing vessels were wanting, and corn for the winter had not been provided in those places, because it was understood by all that they would certainly winter in Gaul.
They were ingenious and industrious, and they carried on a considerable trade in the Bay of Biscay and in the British Channel. They had ships capable of facing the heavy seas which rolled in from the Atlantic, flat-bottomed, with high bow and stern, built solidly of oak, with timbers a foot thick, fastened with large iron nails. They had iron chains for cables.
"State what you regard as necessary as equipment for the proposed expedition," said the general. "Twenty motor boats, each capable of towing several flat-bottomed barges or native canoes, forty mules, a field telegraph, and also a high-powered wireless apparatus, axes, spades, wire cables and drums, windlasses, dynamite for blasting, and provisions for sixty days.
From tree to tree huge parasites stretched like cables vines, and lianas, and various species of convolvulus. Some of these were covered with thick foliage, while others exhibited a surface of splendid flowers. As if in contrast with these bright spots in the landscape, there were others that looked dark and gloomy.
Everything of value that could be conveniently moved was transferred to the English ships, then the Spanish vessels were set on fire, their cables cut, and were left to drift in an entangled mass of flame. Drake took a number of prisoners, and sent a messenger on shore proposing to exchange them for such English seamen as were prisoners in Spain.
In the afternoon the wind even increased in violence, the snowstorms became more frequent, and the sky was dark and overcast. We had service at eleven and again at four. The sun set cold and stormy, promising a wild night. At times the shore was quite hidden by the snowstorms, though only a few cables' lengths off. Monday, February 19th.
