edge* are here horizontal. The truss-piece is half the breadth of the arm ; BO that, 

 when united to the crown, it constitutes, with the other parte, the total breadth of tho 

 arms at those places. 



The shank is now shut upon the crown ; the square is formed, and the nuts welded 

 to it; the hole is punched out for the ring, and the shank is then fashioned. 



The blade is made much in tho way above described. In making the palm, an iron 

 rod is first bent into the approximate form, notching it so that it may more readily take 

 the desired shape. To one end a porter rod is fastened, by which the palm is carried 

 and turned round in the fire during tho progress of the fabrication. Iron plates are 

 next laid side by side upon the rod, and the joint at the middle is broken by another 

 plate laid over it. When the mass is worked, its under side is filled up by similar 

 plates, and the whole is completely welded; pieces being added to the sides, if neces- 

 sary, to form the angles of the palm. The blade is then shut on to the palm, after 

 which the part of the arm attached to the blade is united to that which constitutes the 

 crown. The smith-work of tho anchor is now finished. 



The junction or shutting-on, as the workmen call it of the several members of an 

 anchor is effected by an instrument called a Hercules, which is merely a mass of iron
