THE BASIS OF LIFE IN THE SEA 1 59 



We live on land and are accustomed to strike an annual 

 average of the conditions on our farms. The study of the sea 

 is in its infancy and we know it mostly from investigations in 

 the spring and summer months. Until we know our seas 

 throughout the year in detail we cannot compare their potential 

 productivity with that of our land areas.
