SEDIMENTS IN THE DELTA OF ERASER RIVER 129 



be sufficiently dilute to prevent fiocculation and hence to permit 

 of lamination of the sediments only at times when and in places 

 where large volumes of water from melting ice sheets were being 

 poured into the sea. A possible exception might occur in places 

 where large volumes of river water are being poured into an estuary 

 or into a nearly land-locked part of the sea;, but fiocculation takes 

 place in the Strait of Georgia in spite of the large volume of fresh 

 water brought down by the Fraser, and where the density of the 

 surface sea water is only i.oio, as compared with the density of 

 normal sea water which at 17.5° C. is 1.027.
