 TITLE XL\'IIl.——CO)llL[ERCE AND NAVIGATION.-—~Ch. 1. 799 Sec. +152. The provisions foregoing relating to the measurement of Rules of nwa¤· vessels shall not be deemed to apply to any vessel not required by "}'°“‘°“"l“”"°d*° law  lg registered, or enrolled. or licensed, unless otherwise specially "#%%¥‘glgQ—l_ Prom ° · s<:<,s:5,\·i13,p.,72i Sec. +153. The register tonnage of every vessel built within the United Tonnage. States or owned by a citizen or citizens thereof shall be her entire internal6‘j,[;`@],‘ cubical capacity in tons of one hundred cubic feet each, to be ascertained 83, s. 3,'i·. 13, bp: as follows: Measure the length of the vessel in a straight line along 70-72- the upper side of the tonna c-deck, from the inside of the inner plank, average thickness, at the side of the stem to the inside of the plank on the stern-timbers, average thickness, deducting from this len th what is due to the rake of the bow in the thickness of the deck, ami; what is due to the rake of the sterntimber in the thickness of the deck, and also what is due to the rake of the stern—tin1ber in one-third of the round of the beam; divide the length so taken into the number of equal parts required by the following table. according to the class in such table to which the vessel belongs: TABLE 01-* cmissms. Class one. Vessels of which the tonnage length according to the above measurement is fiftv feet or under: into six equal parts. Class two. Vessels of which the tonnage length accordin to the above measurement is above fifty feet, and not exceeding one liundred feet: into eight equal arts. Class three. Jesse1s of which the tonnage length according to the above measurement is above one hundred feet. and not exceeding one hundred and fifty feet: into ten equal parts. Class four. Vessels of which the tonnage length according to the above measurement is above one hundred and fifty feet, and not exceeding two hundred feet: into twelve equal parts. Class five. Vessels of which the tonnage length according to the above measurement is above two hundred feet, and not exceeding two hundred and nfty feet: into fourteen equal parts. Class six. Vessels of which the tonnage length according to the above measurement is above two hundred and fifty feet: into sixteen equal tts. p&Then, the hold being sufficiently cleared to admit of the required depths and breadths being roperly taken, find the transverse area of such vessel at each int of division of the length as follows: Measure the deptlioat each point of division from a oint at a distance of one-third of the round of the beam below such deck; or, in case of a break, below a line stretched in continuation thereof, to the u per side of the floor timber, at the inside of the limber—strake, after deducting the average thickness of the ceiling, which is between the bilge—planks and limber-strake; then, if the depth at the niidship division of the length do not exceed sixteen feet, divide each depth into four equal parts; then measure the inside horizontal breadth, at each of the three points of division, and also at the upper and lower points of the depth, extending each measurement to the average thickness of that part of the ceiling which is between the points of measurement; number these breadths from above, numbering the upper breadth one, and so on down to the lowest breadth; multi ly the second and fourth by four, and the third by two; add these prodlbcts together, and to the sum add the first breadth and the last, or fifth; mult1ply the quantity thus obtained by one-third of the common interval between the breadths, and the product shall be deemed the transverse area; but if the midship de th exceed sixteen feet, divide each depth into six equal parts, instead of four, and measure as before directed, the horizontal breadths at the five points of division. and also at the upper and lower points of the depth; number them from above as before; multiply the second, fourth, and sixth by four, and the third and fifth bv two; add these products together, and to the sum add the first breadth and the last, or seventh; multiply the
