FURTHER WORK RECOMMENDED. 13 



Many changes will be brought by coming years upon the areas thus 

 mapped, in the springing up of new villages, the organization and naming 

 of townships, and the construction of new lines and branches of railways. 

 It is to be hoped, also, that local observers, as teachers in the common 

 schools and in the colleges and universities of Fargo, Grand Forks, Winni- 

 peg, and other cities, will supplement the work herein described and 

 mapped by adding such portions of the lower shore-liues of Lake Agassiz 

 as have not yet been definitely traced. The sections of new artesian wells 

 should likewise be recorded and studied in comparison with the notes of 

 wells here reported.
