Fig. 2. — Three density curves and three temperature curves, the upper set being the density curves, No. 

 1 density curve is for the readings obtained near F'ive Finger Islands on Sept. 9, as an example of a 

 set where the surface water is of high density and hence little difference between the surface water 

 and water at depth. No. 2 is that for the readings taken in the open Strait, east of Breakwater I., 

 on Oct. 2G, as an example of an instance when the surface water was of low density and hence dif- 

 fered materially with that at depth. No. 3 is made from the averages for the various depths of all 

 the readings recorded in Appendix C. The temperature curves 1, 2 and 3 correspond to the density 

 readings similarly numbered.
