so on, down to the lowest breadth). The 2nd
and the 4th are multiplied by 4 and the 3rd by
2 these products are added together, and to
the sum is added the 1st auI 5,h breadths the
quantity thus obtained is again multiplied by
8rd OF the common Interval or distance between
the %Dreadths, and the produce will then be the
Area OF the Cross-section.
Ii, on the contrary, the midship's depth ex-
ceedS 1854 feet, each depth is divided into 6
equal parts, after which the horizontal bread rs,
IN conformity with the before mentioned direc-
tons are measured at the 5 points of division,
and also at the upper and lower points Of the
depth and numbered from above; the 2nd, the
4th and the 9th are multiplied by 4 and the 3rd
and 9th by 2 these products are added to-
gether, and to the sum total the LIST and 9TH
breadthS are added the quantity thus obtained
Is multiplied by 5rd of the common Interval or
distance between the breadths, and the product
VIII be the Area of the Cr0ss-SeGti0n.
q. Having thus ascertained the superficial
area OF the cross or transverse sections at each
point OF division of the ships length, the caIcu-
htIon OF the ships tonnage must be proceeded
with III the following manner.

length at the stern then, whether the length
be deylded, according to the Table, into 4 or
II parts or any intermediate number of parts,
the second and every even numbered section is
multiplied by i and the 3rd and every odd
numbered section Except the first and las) by

their total are added the first and the last sec
tons If they yield anything, after which, multi
ply the quantity thus obtained by 8rd Of the
common Interval or distance between the sec
tons this product will give the cubic contents
OF the space under the tOnnage-deck which, di-
VIded by 9l,59, expresses in Tons the Tonnage
OF the ship below the t0nnage-Iock.
d. If there be breaks, poop or any other
permanently cIosed-in cabins or spaces on the
upper deck, available for cargo or stores, or
Tor the lodging or accommodation of passen-
gers, the Tonnage of such space shall be as
certained as follows:
The inside mean-length of such spaces is
measured and divided into 2 equal parts; on
the middle Of the height are measured 3 inside
b~readths, namely l at each end and l at the
Middle of the length to the sum total of the
end-Dreadths is added 4 times the middle breadth
and the whole sum is multiplied by 8rd of the
common interval between the breadths the
product will give the mean horizontal Area of
such spaces, which is again multiplied by the
middle height of the space. The product is
divided by 9I,5o and the Quotient, which must
be considered as the tonnage Of the space in
question, is added to the tonnage under the
tonnage-deck.
No addition to the tonnage shall be given for
constructions erected for the shelter of Deck
passengers, subject however, to the approval
OF the Government.
