318 Prof. Bache’s Lecture on the Gulf Stream, 
Il, Pian or THE Work. 
The plan of the work was simple. The temperatures were to 
be ascertained at various depths, at different distances from the 
coast, on sections as nearly at right angles with the stream as 
ee ee sections starting from some point well known in 
iti te 
*¢ 
mperatures were to be taken at distances di- ~ 
minishing as the changes of temperature were more rapid. 
So 
in regard to the depths, the observations were to be multiplied © 
t was 
rapidly exchanging for the warm water of the Gulf Stream, the 
sections diminishing in distance as the source of the warm water 
was approached. 
The vessel’s position was determined with reference to some 
prominent point, Sandy Hook, or Cape May, for example, the 
course run was perpendicular to the supposed axis of the stream, 
S.E., several positions were taken up in succession and at each 
the temperatures ascertained at the surface, at 5, 10, 15, 20, 30, 
50, 100, 200, 800, 400, 600 fathoms, or depths found to apply 
not, without considerable danger, be exposed to the roughness of 
the wind and water in the Gulf Stream in winter, and when we

attempted comparative winter observations, disappointment was 
often the result. The loss of one valuable officer and ten of his

with their results, whenever and wherever brought before hacah 
public, and they have been carefully preserved in the archives
