No. 1806 of 1868.— Mure.— The carrier, to facilitate the winding of 

 several lines and hooks simidtaneously on the winder and to permit one 

 line or hook to be withdrawn at a time without entangling the rest or 

 breaking them, consists of a tablet having at each end a cap or ferrule, 

 the center of which is hoUow to receive a piece of cork in which to insert 

 the barbs of the hooks. On each side are a number of openings reached 

 by a sloping duct, through which the lines are successively and alter- 

 nately passed in a hank till completely wound up, the hooks being fixed 

 in a similar manner, openings being made for their reception on both sides 

 of the apparatus. The hooks are protected by a metal band attached to 

 the cap of the ferrule, one end working on a hinge and the other fixing 

 with a clasp. May have a simple line- winder, which is of the same con-

 with a cover, having an opening at one end through which to draw the 

 lines. Another form consists of an endless band of pasteboard in the 

 shape of a flat cylinder, and the lines are drawn around this, being passed 

 through openings at the sides as before. Hook-carriers consist of a 

 wooden plate with ends terminating in a metal cap having notches for 

 the hooks, which are protected by hinged metal bands, the opposite ends
