and very found, juft over the gravel, at trie 

 bottom of the bog all along the drain. This I 

 effe&ed, by laying two large beams from the 

 top, fo as to form an inclined plain to the bot- 

 tom : then drove down into the bog above, 

 a itrong beam perpendicular, and made it firm 

 byftones; to this, I fixed' a great pulley, and 

 another pulley to the root below, firlt. fepa- 

 rating it by hatches and iron crows from its 

 large arms, which run under the bog : then by 

 running a cable through the pulleys, the united 

 ftrength of 16 or 20 men drew up the largeft 

 roots along the Aiding plain. The men as they 

 drew up the roots, ufually flood upon the firm 

 gravel at the bottom of the drain, the top 

 being in many places too foft for footing. 



Having completed the drain or water-courfe, 

 which is above ninety perches in length, 

 through the great eaft. bog, I fet about making 

 a ftrong bank, from the eaft to the fouth bog> 

 20 perches in length, and from 1 5 to 50 feet 

 broad acrofs the old river, which was 16 feet 

 deep. For this purpofe I drove down a row 

 of long wooden piles, and a fecond row acrofs 

 the river, and made the bank by filling up the 

 intermediate fpace with fods well rammed and 

 preffed down. 



I had the fatisfaction to obferve, when I had 

 made a fecond bank, at the lower or north end 

 of the new drain, to prevent the water from 

 returning back into the channel of the old 

 river, but at much lefs expenfe than the former
