8th. It is now the general opinion, in which the Captain coincides, that we have passed, without knowing when, the great Bank; the weather is warmly tempered by a fine S. W. breeze, and the ship is wafting us delightfully over summer seas: hope again "tells a flattering tale" and conversation runs chiefly on what will be done, and what will be had, on our arrival at the much-desired Port. Last night the full moon exhibited, through a heavy mist, an appearance of several rings of the prismatic colours,--a beautiful effect, which I remember once before to have witnessed in England. 11th. Spoke the brig Spring, of Blyth, homeward bound; and had the no small satisfaction to find that her calculation of longitude nearly agreed with our own late suppositions. This morning the extraordinary conflict between the fish called the Thresher and a Whale was seen near the vessel; the Thresher repeatedly raised itself on the Whale's back, so that its tail was nearly upright, and struck the Whale violently with it on the head; it is said that the Pilot-fish is at the same time wounding him underneath with his sword-snout: they did not however succeed this time, but relinquished their pursuit at the noise {14} which the people made at the extraordinary spectacle. The Thresher appeared to be about six or seven feet long. 16th. A Shark seen in early morning: and a large Sword-fish swam majestically round the ship's bow, probably taking it for a Whale; but finding his mistake he dropt astern, and soon after a shoal of small fish, perhaps endeavouring to avoid him, rose completely out of the water;--his length was about nine feet as we judged, and his form and colours beautiful. Several kinds of birds have lately been seen; among which we viewed with pleasure the "Hagdown" as the sailors say it is always seen on or near soundings; it is about the size of, and somewhat resembles, a Duck.--Many Porpoises too have lately passed us; one of these the men struck, and succeeded in getting it on board, when it was soon cut up and eaten; we were prevailed upon to taste it, and must acknowledge that it could not have been distinguished from a fine beef steak; the gravy was indeed richer.
