Hefcrence to the Engravings of Dr. Cogan's Drag. Plate VI IT. 

 Fig. 1, 2, S, and 4. ■ ' >'■ 



Fig. 1. A shows the drag complete, with two cords, B. 

 and C, attached to it; that at the top, B, is fastened to a 

 ring at D ; the bottom cord is tied to a hole in the iron at 

 E, The six ends of the projecting branches have each a 

 barbed claw, which can be slided forward or drawn back, 

 as may be thought necessary. There is a hollow socket 

 in the upper part of the drag at D, so as to admit the end 

 of a pole to be screwed therein, whenever it may be thought 

 useful. 



Fig. 2. Is the cheaper or more simple drag, and intended 

 only to be used with a pole G,. fastened in its hollow socket 

 by the screw H, and to be used in the manner of a rake, 

 to bring the body to land. It has barbed claws at the extre- 

 mities of its branches LL, moveable backwards and for- 

 wards, which claws slide in a groove made in the extremity 

 of each branch. 



Fig. 3. Shows one of the claws drawn upon a larger scale, 

 screwed to one of the extremities of a branch. In this situa- 

 tion the screw head appears as I, on the outside of the 

 branch, and the claw is within, and does not extend beyond 

 ^ the extremity of the branch. 



Fig. 4. Shows the same barbed claw as its utmost extent, 

 projecting beyond the extremity of the branch. The end. 

 of the worm of the screw, which holds it fast in that posi- 

 tion, appears at K.
