Fig. 10. — Diagram to show the hauls taken at one station. 

 I. — VI. represent hauls of the vertical closing nets; W.n. (weight net), 

 Sh. 1 and Sh. 2 (shear net) and the two surface nets represent horizontal 

 or oblique hauls. The numbers 5 to 60 indicate depths in fathoms. 



Here, out in the middle of the Channel between 

 Ireland and the Isle of Man, the depth was about 

 65 fathoms, and we sank our vertical nets down to 60, 

 and hauled them up through the lower 10 fathoms (I.), 

 the lower 30 (II.), and the entire depth (III.), then 

 through the zones 30 to 20 (IV.), 20 to 10, and 10 to 5.
