BARKANTINE, or Barquantine. A name applied on the great lakes of North America to a vessel square-rigged on the fore-mast, and fore-and-aft rigged on the main and mizen masts. They are not three-masted schooners, as they have a regular brigantine's fore-mast. They are long in proportion to their other dimensions, to suit the navigation of the canals which connect some of these lakes.

BARKERS. An old term for lower-deck guns and pistols.

BARKEY. A sailor's term for the pet ship to which he belongs.

BARKING-IRONS. Large duelling pistols.

BARLING. An old term for the lamprey.—Barling-spars, fit for any smaller masts or yards.

BARNACLE (Lepas anatifera). A species of shell-fish, often found sticking by its pedicle to the bottom of ships, doing no other injury than deadening the way a little:[80]

They were formerly supposed to produce the barnacle-goose! (vide old cyclopedias): the poet, however, was too good a naturalist to believe this, but here, as in many other places, he means to banter some of the papers which were published by the first establishers of the Royal Society. The shell is compressed and multivalve. The tentacula are long and pectinated like a feather, whence arose the fable of their becoming geese. They belong to the order of Cirripeds.

BARNAGH. The Manx or Gaelic term for a limpet.

BAROMETER. A glass tube of 36 inches in length, filled with the open end upwards with refined mercury—thus boiled and suddenly inverted into a cistern, which is furnished with a leathern bag, on which the atmosphere, acting by its varying weight, presses the fluid metal up to corresponding heights in the tube, easily read off by an external scale attached thereto. By attentive observations on this simple prophet, practised seamen are enabled to foretell many approaching changes of wind or weather, and thus by shortening sail in time, save hull, spars, and lives. This instrument also affords the means of accurately determining the heights or depressions of mountains and valleys. This is the mercurial barometer; another, the aneroid barometer, invented by Monsr.

Vidi, measures approximately, but not with the permanence of the mercurial. It is constructed to measure the weight of a column of air or pressure of the atmosphere, by pressure on a very delicate metallic box hermetically sealed. It is more sensible to passing changes, but not so reliable as the mercurial barometer. 29·60 is taken as the mean pressure in England; as it rises or falls below this mark, fine weather or strong winds may be looked for:—30·60 is very high, and 29·00 very low. The barometer is affected by the direction of the wind, thus N.

N. E. is the highest, and S. S. W.

the lowest—therefore these matters govern the decision of men of science, who are not led astray by the change of reading alone. The seaman pilot notes the heavens; the direction of the wind—and the pressure due to that direction—not forgetting sudden changes of temperature. Attention is due to the surface, whether convex or concave.

BARQUE. The same as bark (which see).

BARR. A peremptory exception to a proposition.

BARRA-BOATS. Vessels of the Western Isles of Scotland, carrying ten or twelve men. They are extremely sharp fore and aft, having no floor, but with sides rising straight from the keel, so that a transverse section resembles the letter V.

BARRICADE. A strong wooden rail, supported by stanchions extending[82] as a fence across the foremost part of the quarter-deck, on the top of which some of the seamen's hammocks are usually stowed in time of battle. In a vessel of war the vacant spaces between the stanchions are commonly filled with rope-mats, cork, or pieces of old cable; and the upper part, which contains a double rope-netting above the sail, is stuffed with full hammocks to intercept small shot in the time of battle. Also, a temporary fortification or fence made with abatis, palisades, or any obstacles, to bar the approach of an enemy by a given avenue.

BARRIER of Ice. Ice stretching from the land-ice to the sea or main ice, or across a channel, so as to render it impassable.

The length of the gun is reckoned from the after-edge of the base-ring to the face of the muzzle: but in built-up guns, there being generally no base-ring moulded, and the breech assuming various forms, the length is measured from[83] the after-extreme of the breech, exclusive of any button or other adjunct.
