1. _Stud_, or _studding-sails_, called by the French _Banettes en etui_, are light sails, which are extended in moderate breezes beyond the skirts of the principal sails: where they appear as wings upon the yard-arms. 2. _Stay-sail_; though the form of sails is so extremely different, they may all be divided into sails which have either _three_ or _four_ sides: a _stay-sail_ comes under the first class, and receives its name from a large strong rope on which it is hoisted, called a stay, employed to support the mast, by being extended from its upper end towards the fore part of the ship, as the shrouds (a range of large ropes), are extended to the right and left of the mast, and behind it. The yards of a ship are said to be square, when they hang across the ship, at right angles, with the mast; and _braced_, when they form greater or lesser angles with the ship’s length.

PAGE 54, l. 22. _White as the clouds beneath the blaze of noon._ Before the art of coppering ships’ bottoms was discovered, they were painted white. The _wales_ are the strong flanks which extend along a ship’s side, at different heights, throughout her whole length, and form the curves by which a vessel appears light and graceful on the water: they are usually distinguished into the main-wale, and the channel-wale. PAGE 58, l. 7. _Deep-blushing armors all the tops invest._ In our largest merchantmen, the _tops_, or platforms, which surround the heads of the _lower_ mast, (for every ship’s mast, taken in its apparent length, consists of the _lower_ mast, the _top_-mast, and _top-gallant_ mast) are fenced on the aft, or hinder side, by a rail of about three feet high, stretching across, supported by stanchions; between which a netting is usually constructed, the outside of which was formerly covered with red baize, or canvass painted red, and was called the _top armor_; being a sort of blind against the enemy for the men who were there stationed. This name is now nearly lost, and the netting is always covered with black canvass. NOTES ON THE SECOND CANTO.
