Rivets should be made of good charcoal iron or of a verysoft mild steel, running between 50,000 and 60,000 pounds ten-sile strength and showing an elongation of not less than ninetyper cent, in eight inches, and having the same chemical com-position as specified for plates. A long rivet, holding thick plates together, is rarely tightexcept immediately under the head. The heads are set and thecentre cooled before the hole is properly tilled. If it is a verylong rivet there is a chance of the contraction fracturing thehead of the rivet. In the Forth Bridge, which is made of veryheavy plate girders, the rivets, first carefully fitted, wer
