foundation. It will be attached immediately to the east end of the 

 dam (see sectional drawing in fig. 3), by which you may see the 

 relative position of the turbine and pumping-house, with the inlet 

 canal and the inlet pipes, besides the other leading pipes of the 

 dam and sluice works. By reason of the floods which took place 

 in the spring of this year (1872) the erection of this building 

 was very much delayed. During the late summer the works have 

 made great strides, and it is hoped to have this important building 

 for the waterworks covered before the cold winter sets in. 

 Besides this it is confidently expected that the mounting of the 

 turbines and the wire-rope transmissions of power will be com- 

 pleted this year (1872). The pumps and the iron piping for the 

 water supply must be completed, according to contract, by next 

 spring, and be in actual working order. 



Thus by these measures the inhabitants and the industries of 

 the town of Ereiburg have been most specially cared for, with 

 pure drinking water for their houses, and with water-power for 

 their industries, given them to such an extent that their great 

 advantages will become the envy of far more important towns . 

 In fact nothing more noble can be conceived than these waterworks 

 which are perfected for the sole purpose of making water 

 subservient to man's use — for his home, for his fields, and for his 

 industries in life. 



According to the estimates, the two turbines, the four pumps, 

 the inlet canals, and the double buildings were rated in the first 

 instance at 175,000 frs. (£7,000). Up to the present time the 

 cost by the balancing of accounts gives only 68,272 frs. 27 cents. 

 (£2,730 17s. lOd.) for the buildings, £1,840 for the two turbines, 

 and £314 for the four pumps, or, altogether, not quite £4,880, — 

 so that the estimate for these are not likely to be overstepped by 

 actual expenditure. This favourable result has been very much 

 brought about by the fact that the waterworks could be entirely 

 based on a rocky foundation, and that the necessary hewn blocks 

 of stone for the building were easily obtained on the spot. These, 

 for instance, were to be had from the excavations of the outlet 

 canals and of the turbine house, and generally out of the exca- 

 vations that were necessary to be made in connection with the 

 works. 



3. — The Filter and Pumping Works. Fio. 4. 



In the dammed-up waters of the lake, and behind the dam and 

 sluice works, there is a large tower-like vessel, made out of sheet 

 iron, which contains the filter for the water intended to pass 

 through it. This iron vessel has a diameter of 19| feet, and is 

 16i feet deep. It is set up on the gravel beds of the Saane. 

 Inside it there is a circular casing of 1 feet llf inches thickness, 

 which is made of cement, in order to protect the inner filtered
