Harpoon poles are of a heavy wood, 2" to IVz" dia., length 10' to 12'. 

 They are short and heavy because of the low freeboard of the boat and its 

 lack of pulpit necessitating the striker throwing in a high arc to reach the 

 fish before it sinks. 



From a study of billfish production in Chile, it appears that the accepted 

 concept that the swordtish migration to this part of the continent come 

 from the South, touching Chile about at its mid-point (roughly the Co- 

 quimbo area) and progressing northward with the flow of the Humboldt or 

 Peru Current, is substantially correct. The figure (Figure 11) showing 

 monthly average production from 1948 to 1952 supports this. Zone III,
