_Saturday, July 29th._--“Everything has gone on most admirably during the night.” Such was the report from electricians, and engineers, and officers this morning. The electrical condition of the Cable furnished results most satisfactory to Mr. Varley and to Professor Thomson. The tests showed that in copper-resistance, insulation, and every other particular, the Cable was exhibiting an excellence far beyond the specified standard. Coil after coil whirled off from the tank and passed away to sea as easily as the lightning flash itself; and Valentia was joined to us by a lengthening thread, which seemed stronger and more sentient as it lengthened. In the night the Terrible had vanished, but she came in sight in the morning, and drew up closer to us. As the sea was calm, and the Cable ran out so beautifully, the speed of the steamer, and consequent rate of paying-out of the Cable, were increased; and it looked as if there was really no limit to the velocity at which the process could be conducted under favouring circumstances. Yes; “Heart’s Content” on August 5th was certain. What could prevent it? The fault which had occurred was caused by an accident most unlikely to happen again. So we pored over our maps and marked out the soundings in the little bay in Newfoundland, and imagined what sort of place it was, as men will do of spots they have never visited. At noon our position was, Lat. 52° 33´ 30´´ (another reading, 52° 38´ 30´´), Long. 27° 40´. Distance run, 160 miles. Distance from Valentia, 634·4 miles. Distance to Heart’s Content, 1,028 miles. The Great Eastern had passed over the valley in the plateau where the Atlantic deepens to 2,400 fathoms. At 9 a.m. we had shoaled our water to 2000 fathoms, or 2 nautical miles.
