We also saw and destroyed (without knowing what we were killing) several iguanas--little creatures of the lizard species, that abound here in great numbers. They are said to be a fierce enemy of the serpent tribe, and to engage in long and severe contests with his snakeship, and always gain the victory--running, when bitten by him, to a certain herb that acts as a specific. When we were at Hobartown, I was told of a man, named Underwood, who possessed a sure and speedy antidote for the bite of any snake. The government had offered him a large price for his secret, but he refused to divulge it on any terms. He was a convict of the lowest grade, and represented that he first discovered the antidote by observing the iguana running to, and eating it, after having been bitten by his foe. This remedy, which is vegetable, he states to be very common. Its infallibility is implicitly believed in by the residents; and, from their account, even a stranger cannot refuse credence to its worth, after listening to a recital of the many satisfactory tests it has been subjected to by the faculty. Whilst we were engaged ashore, those who chose to remain on board the ship passed the time in angling. Amongst other specimens of what had been caught, was one known as the snapper, each weighing from twenty to thirty-five pounds. They had scales, and were of a reddish color. Another, known as the groper, from its swimming close to the bottom, weighs from fifty to one hundred and fifty pounds. It has scales on its body, and is black in color. Both these fish have ivory teeth, from a quarter to three-quarters of an inch in length, and of the same shape as those of the sperm whale. Both are good eating, salted or fresh. They require a strong line and stout arm to secure them. Beside these members of the finny tribe, there are also to be found here others of less note: the mackerel, herring, benita, salmon, and whitings--existing in great numbers. We caught and salted a barrel of them; but, from an excess of salt, they were unpalatable, and we were forced to heave them overboard when we got outside.
