The northern termination of the highland over the south-eastern part of the island which marks Sea Elephant Bay was very apparent as we approached. In the evening we anchored in seven fathoms on the north side of Sea Elephant Rock, which we visited the following morning. It is nearly a mile in circumference, and 120 feet high, clothed with a coarse wiry grass. A small vessel if properly moored might find shelter under it from easterly gales. We were surprised to find the time of high-water here nearly two hours earlier than at Three Hummock Island; the flood-stream came from the southward. WILD DOGS. Of the number of wild dogs that we had heard of as being on this island, we saw only two. From the bones we found of others it is more than probable that they live upon each other at the seasons of the year when the mutton birds having departed; they would otherwise have to depend solely for subsistence on the few shellfish adhering to the rocks. This reminded me of what I once witnessed on an island off the eastern coast of Patagonia. Several herds of deer had once existed upon it; but some persons having turned a number of dogs loose, the original inhabitants were soon destroyed, and the newcomers afterwards devoured each other, so that when I saw them, but a small remnant remained. The dogs on Sea Elephant Rock, which were left by sealers, had grown so wild that they would not allow us to approach them. I saw here some small penguins, a bird we rarely met with in the Strait. This part of King Island is clothed with thick scrubs, among which we saw numerous tracks of kangaroos, a certain sign that it is not much frequented by civilized or uncivilized man. Leaving this anchorage we examined the eastern shore of the island which we found, as I have before described, to be low and sandy. Passing along two miles from it, we had a depth of from 8 to 12 and 15 fathoms. As we approached the northern end, the character of the coast changed, it being formed by rocky points with small sand bays intervening. The reef laid down by the French, two miles from the North-East extremity of the island, we found to be only half a mile South-South-West from it, one of the many errors we discovered in the French chart of the strait. It is a small ugly ledge quite beneath the water, and from the absence of rocky points on the low sandy shore it fronts, is quite unlooked for. NAVARIN AND HARBINGER ROCKS. The next day, February 13th, we examined the dangers fronting the north side of the island, consisting of Navarin and Harbinger Rocks, neither of which we found so formidable or so far from the shore as had been reported. The former lies only a mile and a half off the north end, and although we did not pass between it and the shore, there is little doubt that a passage exists. We passed between the Harbinger rocks in 27 fathoms; this great depth in their immediate vicinity, gives no warning of their proximity in the night or during thick weather.
