THE KEER DRAG. 19 



from a row-boat, keeping hold of the tow-rope 

 and taking care that the mouth of the net pre- 

 serves its position, it should be towed leisurely 

 about, the iron bottom traversing the ground and 

 the quantity of contents obtained soon leads to a 

 knowledge of the best localities. Should the 

 mouth of the net get foul of any opposing sub- 

 stance on the ground, it is only necessary to push 

 the boat back in the line of its previous course 

 and the net comes clear, being thus pulled upon 

 in the opposite direction. 



When inclined to examine the net, the frame- 

 work may be raised by the tow-rope high enough 

 to lodge the wooden beam over the edge of the 

 boat's stern, but higher than that is unnecessary ; 

 the tail of the net is to be hauled in, untied, and 

 the contents shaken into a tub for examination. 

 The tail of the net being retied, the frame may 

 be lowered and towed about as before, and while 

 the net is again at work at the bottom the col- 

 lector may be engaged over the contents of his 

 tub at the top.
