Round the Shores of this Island, and at this Season, _(July, August_ and _September_,) there is a great Resort of Whale-Fish, tame, and sporting very nigh the Ships as they sail in, always in Pairs, the Female much the smaller, and often seen to turn on their Backs for Dalliance, the Prologue to engendring: It has an Enemy, called the Thresher, a large Fish too, that has its Haunts here at this Season, and encounters the Whale, raising himself out of the Water a considerable Heighth, and falling again with great Weight and Force; it is commonly said also, that there is a Sword Fish in these Battles, who pricks the Whale up to the Surface again, but without this, I believe, he would suffocate when put to quick Motions, unless frequently approaching the Air, to ventilate and remove the impediments to a swifter Circulation: Nor do I think he is battled for Prey, but to remove him from what is perhaps the Food of both. The Number of Whales here has put me sometimes on thinking an advantageous Fishery might be made of it, but I presume they (no more than those of _Brasil)_ are the Sort which yield the profitable Part, called Whale-Bone: All therefore that the Islanders do, is now and then to go out with two or three Canoes, and set on one for Diversion. The Rocks and outer Lines of the Island, are the Haunts of variety of Sea-Birds, especially Boobies and Noddies; the former are of the Bigness of a Gull, and a dark Colour, named so from their Simplicity, because they often sit still and let the Sailors take them up in their Hands; but I fancy this succeeds more frequently from their Weariness, and the Largeness of their Wings, which, when they once have rested, cannot have the Scope necessary to raise and float them on the Air again. The Noddies are smaller and flat footed also. What I would remark more of them, is, the admirable Instinct in these Birds, for the proper Seasons, and the proper Places for Support. In the aforemention'd Months, when the large Fish were here, numerous Flocks of Fowl attend for the Spawn and Superfluity of their Nourishment; and in _January_ few of either; for the same Reason, there are scarce any Sea Fowl seen on the _African_ Coast; Rocks and Islands being generally their best Security and Subsistance.
