 4-9. 



A series of observations were made in 92 wells, to determine the 

 varying levels of the water as compared with that in the Elbe. The 

 subsoil on the right bank is fine gravel and sand ; on the left bank 

 coarse gravel and pebbles. The impervious beds below consist mainly 

 of ragstone, at depths varying from 39 to 54 feet. The variations in 

 level were most sudden in the coarse gravel. The rate at which water 

 flows from one district to another is ascertained, and it is now possible 

 to localize contamination and to point with precision to its source. 

 Some pumps in the midst of the old city give very pure water ; the level 

 there is low and the soil very fine. (From an abstract in * Proc. Inst.
