Thekeel arrangements have been previously described, and it willbe remarked that the side intercostal plates, which are | inch thiclc,are secured to the bottom plating by double angle-irons 4 by 4 by\ inches. The importance of this mode of connection has beenalready alluded to, though many shipbuilders neglect it. Thestringer plates are not connected to the outside plating on thelower and middle decks, but on the upper deck the stringer is runout between the frames and connected to the sheer-strake. Thevertical stringer or clamp between the upper and middle decks isworked in order to give longitudinal strength. The garboard-strakes of the China are 1 inch thi
