eJ biv'.ies de- diagonal one when pulled torward, scraping the ground, out 



scribed. not entering it. Each drag lias a swivel at both ends of its' 



shaft or stem. Its" whole length, including swivels, is about 

 nineteen inches. At nine Indies and a half from the top, 

 the hooks, which are three onlj' at their base, but which are 

 subdivided at eight inches from their ends, take their rise. 

 They are curved, and their points when turned up again 

 are about four inches below the level of their tops, and thir-* 

 teen inches asunder; and the outside point of each sub-divi- 

 sion is thirteen inches from its adjoining one. The extreme 

 points are split and formed into a double hook, very sharp 

 and pointing towards the stem. 



Holes are bored through the bar A at equal distances, so 

 as the hooks when suspended may approach each other 

 within five inches. Through those at the end, which are 

 larger than the others, and made close to the pieces of wood 

 let into the bar, the principal or drawirrg ropes D D pass. 

 This rope is of considerable length and strength, and goes 

 through the top swivels of all the drags. It is then made 

 fast by wooden wedges driven into the holes through which 

 it passes, at such a length as will suspend the two end drags 

 a i-evf inches below the end of the pieces of wood let int^ 

 the.bar. The other two drags are suspended at the same 

 distance from the bar by lines of an equal length coming 

 through the holes in the bar, and tied to their top swivels. 

 These two drags, as well as the two end ones, are made 

 fast to the principal or drawing rope at equal distances witK 

 a piece of tar-line tied to their top swivels. And the two 

 outside drags are kept in their proper situation by the prin- 

 cipal rope going through a staple fixed in the pieces of 

 wood let into the bar ; and the two others are kept either 

 from approaching or entangling with one another, or the 

 outside ones, by bored pieces of wood, a a, of equal lengths, 

 placed between each drag at the boltoin, through which and 

 their bottom swivels a rope made fatt to the bottom swivels 

 of the two outside drags passes. The drags, however tied 

 or fastened their swivels may be, always have their own ro-_ 

 tury motion free, consequently their points by their own 

 gravity will always assume and retain their proper position
