THE PROPOSED ROUTE OF THE CROCKER LAND EXPEDITION 
(a) Geography.—tThe coast lines and interiors 
will be mapped by plane table, barometer, con- 
tinuous tracing of valleys, ete.

ogy of Ellesmere Land and Grant Land have been 
made by the Norwegians under Sverdrup and the 
English Expedition of 1875-6, but their work was

and the relative abundance and character of the 
igneous and sedimentary rocks was learned; and 
nothing concerning the physiographic conditions of 
these areas was determined. It is proposed there- 
fore to make detailed areal studies of the geology
