 we were obliged, unfortunately 

 for ourselves, to try it fre-

 line ends in a loop passing 

 through an eye in the centre of 

 a bar of iron r. The bar ter- 

 minates at one end in a claw 

 and at the other in a second 

 eye, to which a chain is at-

 sharp, spade-like lip, is fixed to 

 a long and rather heavy iron 

 rod D, with an expanded rudder- 

 shaped end to steady it in pass- 

 ing quickly through the water, 

 and beneath this an eye, which o i 



fits the claw of the bar p. A 

 door B fits the scoop to which 

 it is hinged, and it is also 

 hinged to the arm c, which, 

 when held in a vertical posi- 

 tion, keeps it open. The arm o 

 is attached by the chain to the 

 eye in the bar p, and the arm 

 and chain correspond in length 

 to the rod d. Two teeth ee
