slble on several accounts. However, the principle of the 

 former gave me the hint, and led to my first invention 

 (Fig. 10, Plate I.)-, which consists merely of a flat plate 

 of brass, cut into the form there described. 



The line winds round the centre part between the four 

 points a, b, c, d, where the plate may be less than a 

 quarter of an inch in thickness ; but it grows gradually 

 thickeras it approaches the ring, which may be half an incb 

 ip breadth : the circle should be equal to the part of the 

 rod you would apply it to, making allowance for the wold- 

 ing, which is put on the; ring to prevent its chafing, the rod. 



The length (i. c. breadthwise) of such a reel,, may be 

 three inches and an half at the broadest part, and about 

 an inch and three quarters from the upper edge of die 

 ring to die top. 



The increase of thickness towards the ring will not be 

 objectionable, when we consider that the line will give the 

 other, or flatter part of the reel, at least an-equal.diameter. 



I have since improved upon diis reel, by causing it to 

 move on a pivot rising from the ring, which is thus inde- 

 pendent of the ivkirl ;. the pivot, or spindle, goes through 

 the bottom, and top of die frame, and is rtvetted.; attack 

 upper corner of the ivhirl is a stud, cased; with a move- 

 able cylinder moving round die stud, which serves as a 

 handle, or winch, wherewidi to turn the whirl when, 

 winding up. See Fig. 1 1 , Plate L 



It is worthy of remark in diis place, diat the quantity? 

 of line given or received by a barrel-reel, is very unequal. 

 When die barrel is nearly full, it is at. its greatest power 

 f augmentation or of diminution;, but as it gradually 

 empties, it keeps losing in proportion, till it scarcely, 

 winds, or supplies any efficient quantity of line.
