second gig. At 2.10 p.m. hove up dredge containing some pumice-stones, and stood in 
to within 1|- miles of the west side of Tristan da Cunha. At 3.50 p.m. sounded in 
550 fathoms, Hard Ground (Station 135g). Put dredge over a third time, and veered 
700 fathoms. At 5.45 p.m. the dredge was hauled on board containing several specimens. 
At this time the ship was close to the island, and for a moment the clouds, which had 
veiled the summit for the last few days, opened and revealed the whole island of Tristan 
da Cunha from its base to its snow-clad peak ; a sketch of the same was obtained. 
At 6.15 p.m. made all plain sail and proceeded towards the Cape, with a favourable 
breeze from the N.W. Temperature of air at noon, 51 0, 8 ; mean for the day, 51 c, 6.
