level. This is approximately true only with regard to the balance of a mass of the berg, not with 

 regard to height and depth. A berg may show an elevation of one hundred feet above water and 

 yet its depth below may not exceed double that amount ; but its volume or mass will be about 

 eight times the mass over the surface. Hence, while icebergs ground in thirty and forty fathoms 

 of water they may expose a front of one hundred feet or three hundred and fifty feet, the broad 

 massive base supporting a mass about one-ninth of its volume above the sea level." 

 As to the movements of cod, Professor Hind frames the following table :

From this table the following law is deduced : 



"Over an area extending northerly from Conception Bay for seven hundred miles the cod 

 approach the shore about one week later for every degree of latitude we advance to the north. 

 These tables show also that for a period of about forty days the codfishing goes on simultane- 

 ously during August and September, throughout the length of a coast line extending from lati- 

 tude 47° to latitude 58° 30' in one continuous line, or more than seven hundred statute miles ; 

 hence it appears that the migrations of the shoals of this fish are merely from deep-water winter 

 fishing-grounds to the nearest coast spawning-grounds, and from the coast to the nearest deep-
