But the capacity can be varied to any workable extent. 

 The largest stock pattern by these particular makers 

 would carry 3,200 fathoms, and the smallest only 

 200 fathoms of ij-inch rope. 



A cargo winch can be used for all deep-water work 

 if it carries a largish, deeply grooved drum for winding, 

 of (say) 18 or 24 inches diameter, in addition to the 

 ordinary small barrels. This drum will only carry 

 two or three turns, and the wire must be taken up, as 

 it comes off the drum, on to a storage reel of some 

 kind. It is no small labour to reel up 1,000 fathoms 

 or so of wire rope by hand power, and as a rule it 

 cannot be taken up as fast as the winch can deliver it ; 

 the method is therefore wasteful of both time and 

 labour, and the storage reel should, if possible, be 

 driven mechanically. If a fairly powerful cargo winch 

 is already on board, which it is not desired to displace, 

 we should recommend that a one or two horse-power 

 steam engine should be fixed behind the winch, so 

 that it could drive, directly or by chain gear, which- 

 ever storage reel was required at the moment. A 

 recent expedition used an electric motor for this work. 

 Another plan which has been suggested is to drive the 

 storage reel by an endless rope from the small barrel
