But off Shelburne (Fig. 29) the upper layers, clown to 40 meters or so, 

 were uniformly fresher than 32%o across the whole breadth of the shelf. 

 And salinity, like temperature was lower over Le Have Bank (Fig. 30) 

 than immediately north of it, a fact connected with the eddy-like 

 circulation in this region (p. 182). Contrasting with the low salinity 

 of the upper layers, that of the bottom waters of the basins off Shel-

bume and Halifax and on Emerald Bank (Fig. 30, 31) was very high, 

 the latter being as salt as the water over the continental shelf off 

 Shelburne (Fig. 29, 30). But, as pointed out, the latter was itself 

 considerably fresher than the water at corresponding locations on the 

 slope further west, its maximum salinity being only about 34.9%o,
