Lakes. 45,5, 



included those dammed in by Eskers or Kames, well 

 known on a large scale in Finland, and good examples 

 of which, on a smaller scale, may be seen at Carstairs, 

 and in the beautiful grounds of Castle Kennedy near 

 Stranraer. Many of these lakes since their formation 

 have got filled with alluvial detritus, and are now peat 

 mosses. There are also many small hollows formed in 

 original irregular accumulations of the boulder-clays 

 of Northumberland and Durham, now filled with lami- 

 nated clays, sands, and bearing fresh-water shells and 

 plant-remains, and some of these shallow lakes still 

 exist as such. 3rd. Moraine-dammed lakes, which I 

 think on the whole are scarce, for many that appear 

 to be so are in reality more than half rock-basins-, or 

 only dammed up by moraine-matter for a part of their 

 depth. 



Of lakes in Britain, formed by sinking of the ground, 

 I know of none, save a few pools of water formed by 

 the infalling of New Red Marl above salt-mines and 

 brine-pits.
