A longitudinal bulk- head, if built suffi- ciently strongly, is the best means yet devised of counter- acting these two tendencies. If you look at the cross sectional plan of the ffi; tUun.

The value of her double bottom was proved when sho toro a hole about l0Ofeetlong in the outer skin upon a rock, but continued her voyage without her safety being impaired. Tho Maaretania has double sides extending from the bottom to the water- line, and, after the loss of the Titnnic, it was determined to give the White Star liner Britannio (since treacherously sunk by the Germans while serving as a hospital ship) double sides, and to alter the Ol'ympic, l.
