FIG. 3. 



DIAGRAM ILLUSTRATING METHOD OF DREDGING 



The ice (which is supposed to be five or six feet in thickness) and the bed of the sea are 

 shown in section. The vertical lines mark the sea-ice, and their cessation indicates the 

 positions of the two holes kept open for the purpose of dredging. One man is shown 

 hauling the dredge, and another is paying out the spare line to lessen the strain which 

 tends to lift the dredge off the ground. A few feet in front of the dredge a weight is seen, 

 which series to keep the dredge down, and at the same time by the length of its attaching 

 cord maintains it in the right position. The weight was sometimes a lump of kenyte tied in 

 a cloth, but generally some discarded parts of a motor-car were used.
