Upon the plating of the flat threelongitudinal bearers d, d, d are worked, and upon their upper edgesa horizontal plate 1^ inch thick is secured, to which the bearingis afterwards bolted. The bearers are about 15 feet long, andbeing secured to the flat by double angle-irons, give ample strengthto resist the strains consequent on the transmission of the thrustof the propeller. It should be remarked tliat this very efiScientbearer only requires for its construction the addition of the trans-verse frames e, e, e, the longitudinal bearers d, d, d, and the hori- Miscellaneous Details.
