A WEED-NET 283 



forms an impenetrable barrier to the rest of the 

 weeds which are coming down-stream. At night 

 the lower rope is slackened, and the weeds allowed 

 to escape ; the check is taken off one of the wind- 

 lasses, and the net is brought across the river by 

 means of the one on the opposite side, cleared of 

 any weeds which may be still adhering to it, and 

 spread out to dry. 



This arrangement is made use of daily during 

 the season, being put down early every morning 

 and removed at night. It is as simple and effec- 

 tive as anything can possibly be ; and when it is 

 down, although there may be many tons' weight 

 of weeds behind the net, which is consequently 

 subjected to enormous pressure, not one single 

 particle of weed is able to pass. 



All honour to the inventor ! 



Of course, it is necessary to select a suitable 

 place for the baulk to be placed, and the forma- 

 tion of the bed of the river at the spot at which it 

 may be desired to place such a contrivance must 

 be taken into consideration.
