 hooks, the bars must be made in such a 

 form as to admit of cutting the barbs ; and 

 each piece, which serves for two hooks, is 

 larger at the ends, so that the bar appears 

 in the form of a double pointed spear, three, 

 four, or five inches long: the bars for the 

 finer hooks are somewhat flattened. The
