their efforts to get her off were ineffectual; she had struck upon the shoal at the top of high water. On going on board of her I found Captain Crozier had made every preparation for heaving her off when the tide again flowed, having lightened the vessel as much as possible by starting the water, and landing the stores. As soon as the tide began to rise I returned to the Erebus with our boat's crews, and warped her near to the Terror, the more readily to afford her assistance, should it be required: but she floated off before high water without having sustained any damage, and anchored to the eastward of the point in six fathoms. Our boats were now employed refilling her water-tanks, whilst her own crew were re-embarking and stowing away the stores and provisions that had been landed to lighten her. Assisted by Mr. Tucker and Mr. Davis, I obtained the annexed survey of the harbour, and it employed those officers two entire days to complete the soundings. Our observations were made on a small beach near the shoal point, and is marked + on the plan of the harbour. It is in latitude 52° 33′ 26″ S., longitude 169° 8′ 41″ E., the magnetic dip 73° 53′, and the variation 17° 54′ E. The few days' observation of the tides, reduced to the times of full and change of the moon, gave high water at twelve o'clock; presenting also the same irregularities as were observed at Rendez-vous harbour, Auckland Island. The amount of rise and fall at dead neap tides was forty-three inches.
The dip and variation above recorded are those
