Dec. 12.Our observations being completed, we re-embarked the instruments and observatories, and having repeated our experiments for determining the amount of deviation produced on the compass and dipping needle by the iron of the ships, we weighed on the morning of the 12th, and stood out to sea. As we passed Shoe Island at a distance of about fifty feet, the compasses were deviated nearly two points from their proper direction; showing in a striking manner the very extraordinary magnetic power of its component rocks. Three or four miles to the eastward of Ewing Island we found a very strong tide ripple; when, being well clear of the land, we shaped our course for Campbell Island, distant about one hundred and sixty-three miles. The weather throughout the day continued moderate and favourable, but a dense haze over the Auckland Islands soon concealed them from our view.
