CAPTAIN J. W. COLLINS, Gloucester, Massachusetts: 



Collins's improved adjustable marine drag. (6.) 



Full size for fishing vessels. It consists of a strong iron hoop, jointed and 

 braced, so that it can be folded and stowed away in small compass 

 when not in use. To this is attached by interlocking hoops a heavy 

 canvas bag, which will fill with water when thrown overboard -and 

 hold the vessel steady, nearly head to the sea and wind, and with only 

 a moderate leeway. The drag, when in use. is secured to a hawser by 

 a chain bridle, and can be suspended at any required depth by means 

 of a buoy. A line is attached to the bottom of the drag, so that it can 

 be tripped and easily hauled in when its use is no longer necessary. 

 The ad\antages of this drag are that it is always ready for use, being 

 easily adjusted in a few moments when needed; that it can be un- 

 rigged and stowed away when not in use ; that it can be constructed 

 at a moderate cost, and that it promises to secure the desired eud 

 much better than the drags ordinarily employed for the same purpose. 

 Dimensions : Circumference of hoop, 18 feet ; length of cross-bars 

 (each), 5 feet 10£ inches; size of h'on (hoop and bars), 1J inches; 

 length of bridle chains (each), 5 feet ; circumference of bag, 19 feet ; 

 depth, 4 feet; canvas No. 0, white cotton duck; buoy, 7-gallon keg; 

 buoy line, 1^-inch manila rope, 10 fathoms long; tripping line, 2-inch 

 manila rope, 25 fathoms long. This drag is used to insure the greater 

 safety of vessels in heavy gales, and also to prevent them from drifting 

 so rapidly to leeward, as they do when it is not employed. It is se- 

 cured to a hawser or chain and paid out from a schooner's bow, the 

 distance varying from 25 to 75 fathoms. — {Collins.)
