values of the temperatures nnd aillnlties throughout the period dealt 

 with, it will be noted thit there ire con alder Able vnr1«tions in the 

 conditions from ye'^r to yenr. Viflth regard to the temperature values 

 nlone, it is seen th-^t there is « direct rel«i tion?.hlp betv/een the 

 temperf^tures of the surface waters *?nd the temperatures of the waters 

 in the lower levels. This me^^ns that there must be some means of 

 transfer of heat in one direction or another between the various levels. 

 During the summer months when the sun's he-^t is being absorbed by the 

 surface l°yers, very little of this heat can be tt'-ansf erred by con- 

 duction or direct radiation to the lower levels, due to the Increased 

 stability of the waters in the surface layers. The direct relation- 

 ship noted between summer temperatures at the surface and summer 

 temperatures at the bottom indicates th«> t a highly efficient mixing 

 process is at vjork in the Bqy of Pundy. On com.paring the maximum 

 temperatures given for the various years it is seen that the years in 

 which a higher surface tem-perature prevails, are also those in which high 

 temperatures are found in the waters at the greater depths. The lowering 

 of the temperatures at the surface tends to set up ordinary convection 

 currents so that the process of mixing of the waters at the various 

 levels is enhanced. Colder surface temperatures ^re also shov/n to be 

 Indicative of colder bo'ttom. temperatures. At this point It might be 

 argued that variations of surface tem.peratures in this region would be 

 indicative of the variations in the bottom^ temperatures. It is readily 

 seen that though the heat transferred fromi the water at the surface 

 determines the temperatures of the waters of the i^aj of Fundy, the 

 temperatures of the bottom v/aters carried into the Bay control the 

 temperatures of the deep v/aters in the Bay. The actual part played 

 by the various agencies depends in the first case upon climatic
