part near the right of the diagram, i.e., near Letite passage. Thus we may conclude 

 that, while' the warm water passes out through the Western passage, cold water from 

 outside enters through Letite passage. This cold water does not appear in the sec- 

 tion, but may be seen from the tables. 



It^ is claimed by the fishermen that a current runs northeast along the north 

 shore of Deer island from the Western passage. This probably meets the cold water 

 entering at Letite passage and the two currents mingle and run out into the bay. A

little water at a slightly higher temperature appearing at the bottom at station 14 

 is probably due either to this current coming up from the Western passage, or to a 

 .small current running out from the mouth of the river. This water of higher- tem- 

 perature is indicated by a dotted line. 



It is very -unfortunate that sufficient data with regard to the densities to confirm 

 these conclusions were not obtained, and that direct observations upon the currents 

 could not be made, but it is felt that the work gives a foundation upon which further 

 and more definite investigations may be based, either to confirm and extend the con- 

 clusions reached, or to demonstrate their error and provide the correct explanation 

 of the conditions.
