TROUT-FISHING IN SWEDISH LAPLAND. 67 



after trying for half an hour longer I changed to a 

 couple of trout flies, and soon began to be busy, play- 

 ing two pound and one pound grayling, and small, 

 dashing trout into the landing net, which one of the 

 young Swedes held to receive them. It was getting 

 on for luncheon time when Edholm came up and said 

 he had something to show me which must be seen 

 before eating ; so, going back to the boat, we rowed to 

 the next pool, a hundred yards away, and after following 

 a path for a short distance, came in sight of a substantial 

 log house in the middle of the river, built on great fir 

 piles and connected by a stone weir or dam with the shore. 

 Below the dam the river was steep, broad, and stony. 



This, then, was the object of our search, and one that 

 all the party looked forward to showing me with such 

 impatience. It was apparently nothing but a common 

 flour-mill, consisting of a funnel-shaped turbine, down 

 which the water rushing turned a wheel and caused 

 the heavy millstone to revolve. 



While I was wondering what a great flat chamber, 

 built out on to the river bed below, meant, and 

 through which the water percolated, Edholm un- 

 locked the door, and letting go a heavy lever, stopped 

 instantly the flow through the turbine. Then with 

 our combined efforts we threw open a great trap- 

 flooring, and a sight was presented to my astonished 

 gaze that I shall never forget. 



I can see that mill-stream shining, 

 As when I saw it last. 



The water within was boiling like a gigantic caldron.
