Tim leader is a straight row of plain stakeH-ii to :H fftt apart, niniiiiit; nut tVoiii tlu- shore, and varies in length 

 aecording to tin: conformation of the bottom. The walls of Iho three pounds are formed liy driving stakes into the 

 bottom of the river and covering them with net of 'i to 2i ineh mesh, of It) lo 24 thread eottoii twine. None of the 

 ponnds have any other bottom than the bottom of the river. The depth of water in the hsli i)onMd is from -2 to 1.'. feet 

 at low tide. 



In bnildiiig a weir the points lettered are fixed by measurement, and all others by the eye. 



The dislanees are as follows: 



a to b, 14 fei't. I) to c, 14 feet, c to d, 4 feet, d to e, 18 feet, c to/, 5 feet. / ti> </, 5 feet, g to k, 25 feot. </ to 

 /i, l(i feet, k to i, -2 feet, i to^, 16 feet, b to m, :W feet, e to n, 20 feet, i to 0, 18 feet, a to /, 24 feel. 



The above <limensioiis are given by Mr. J. L. Browne, of Bowdoinham, as those of his weir, which is of nsnal form 

 and tlimensions. 



A weir of this pattern is intended to take tish either ascending or descending the river. The lisl tlines show 



their conrse in entering the weir and ill working forwanl to the Hsh ponnd. Eroiii the lish ponnd they are taken 

 with it "tnek" or "purse-seine." This implement has a woojeii staft' at either end, corks on the niiper edge, ami 

 Iieavy sinkers on the lower edge. To the loweredgeare also attached rings, through whiih runs the purse line, which 

 passes up the staves to the hands of the tishermeu ; one staff is jilaiited at i and the net is then paid out from the boat 

 across the entrance and around by the wall at o, *'i o, &c., until the two staves are brought together again at i, when 

 the seine is pursed up, by hauling on the purse line, and the whole uet with the inclosed lish is thou hauled aboard 

 the boat.
