Sweers Island appeared to be very woody, and bounded by low dark cliffs on the north-east side. We found a long extent of foul ground, with a dry reef near its outer end, extending off two miles in a South 33 degrees East direction from the South-East extreme. Our anchorage was in 5 1/2 fathoms, nearly abreast of a remarkable and solitary sandy point on the above-mentioned island. As we beat up, the navigable width between this and Fowler Island was found to be one mile, and the depth 4 and 5 fathoms. INVESTIGATOR'S WELL. A party was immediately despatched in search of the Investigator's well. Previous to landing, the whole island appeared to be perfectly alive with a dense cloud of small flying animals, which, on our reaching the shore, proved to be locusts in countless numbers, forming a complete curtain over the island. They rose from the ground in such prodigious flights at each footstep that we were absolutely prevented from shooting any of the quails with which the island abounds. This annoyance, however, was only experienced for the first day or two, as the locusts winged their flight to Bentinck Island, leaving the trees only laden with them; out of these they started, when disturbed, with a rushing noise like surf on a pebbly beach. FLINDERS' WELL. The Investigator's old well was discovered half a mile eastward of the point, to which I gave the name of Point Inscription, from a very interesting discovery we made of the name of Flinders' ship cut on a tree near the well, and still perfectly legible, although nearly forty years old, as the reader will perceive from the woodcut annexed. On the opposite side of the trunk the Beagle's name and the date of our visit were cut. It was thus our good fortune to find at last some traces of the Investigator's voyage, which at once invested the place with all the charms of association, and gave it an interest in our eyes that words can ill express. All the adventures and sufferings of the intrepid Flinders vividly recurred to our memory; his discoveries on the shores of this great continent, his imprisonment on his way home, and cruel treatment by the French Governor of Mauritius, called forth renewed sympathies. I forthwith determined accordingly that the first river we discovered in the Gulf should be named the Flinders, as the tribute to his memory which it was best becoming in his humble follower to bestow, and that which would most successfully serve the purpose of recording his services on this side of the continent. Monuments may crumble, but a name endures as long as the world. Being desirous of ascertaining if now, in the dry season, water could be obtained in other parts of the island, I ordered a well to be dug on the extreme of Point Inscription, a more convenient spot for watering a ship, and at a depth of 25 feet met excellent water, pouring through a rock of concreted sand, pebbles, and shells.
