72. Double-chain fastening.

73. Lashing for "ram" block, or "dead-eye." The ram blocks, a and b,

are strapped by the cords, e, which hold them; the small lanyards,

d, pass through the holes to make the connection, and as they are

tightened give the requisite tension to the cordage; the ends are

fastened to the main rope. Usually one of these dead-eyes is held by

an iron strap to the point where it is required to fix and strain the

cordage, which is ordinarily a shroud.
