234 TUREE CRUISES OF THE “ BLAKE.” 
warmer water which joins the Florida Gulf Stream is driven 
into it through the Old Bahama Channel, the temperature of 
which seems to be very warm, being higher than we find it at 
equal depths to the eastward nearer the Windward Passage. 
The variable cold bands which have been traced in the course 
of the Gulf Stream may also be due not wholly to cold water

from an arctic current, but in part to the cold water of lower 
and colder layers of the Florida Stream itself. 
A comparison of the temperatures of the different sections 
across the passages of the Windward Islands, the Straits of 
Florida, and the Straits of Bemini is interesting as showing that 
from the close agreement of the temperatures themselves across 
these lines there is nothing to indicate that a powerful current 
flows to the northward through the Straits of Bemini, or that 
similar currents, though of less velocity, pass through the Straits
