Some alarm was caused by the stoppage of the continuity signals, but after a time they reappeared. The Niagara deviated from the great arc of a circle on which the cable was to be laid, and the error was traced to the iron of the cable influencing her compass. Hence the Gorgon, one of her consorts, was ordered to go ahead and lead the way. The Niagara passed several icebergs, but none injured the cable, and on August 4 she arrived in Trinity Bay, Newfoundland.

The Agamemnon made an equally successful run. About six o'clock on the first evening a huge whale was seen approaching on the starboard bow, and as he sported in the waves, rolling and lashing them into foam, the onlookers began to fear that he might endanger the line. Their excitement became intense as the monster heaved astern, nearer and nearer to the cable, until his body grazed it where it sank into the water; but happily no harm was done.

The signals from the Niagara became very weak, but on Professor Thomson asking the electricians on board of her to increase their battery power, they improved at once. At length, on Thursday, August, 5, the Agamemnon, with her consort, the
