4.  “Geological  Notes  on  the  Bridgewater  District  in  Eastern 
Ontario.77  By  J.  H.  Collins,  Esq.,  F.G.S. 
[Abstract.] 
The  plateau  of  the  Bridgewater  district  consists  chiefly  of  gneiss 
and  mica-schist,  with  subordinate  beds  of  white  marble,  quartz- 
conglomerate  and  quartzite,  and  some  veins  of  ‘  giant-granite.7  The 
geneial  dip  of  the  gneissose  series  is  eastward. 
Iho  Author  notes  the  effect  of  frost  in  splitting  off  flakes  of  the 
gneissose  rocks  and  conglomerates,  especially  on  the  bare  glaciated 
surfaces,  and  suggests  that  many  of  the  smaller  and  shallower 
lakelets  may  have  originated  by  this  process. 
The  conglomerates  are  described  as  gneisses  and  mica-schists,  with 
subordinate  pebble-beds. 
The  occurrence  of  gold  in  quartz-veins  near  Flinders  and  at  Madoc 
is  noted ;  and  amongst  other  economic  products  are  the  micas  of  the
