the marshman, the pump mills are set to work, and 

 the big wheels or the turbines throw thousands of 

 gallons per hour into the sluices connected with the

 gates at the wall-side are opened, and much water 

 let off in this way. In the strong current made by 

 the falling water are borne many Three -spined 

 Sticklebacks, which, still descending on the almost
