 the inner end of Flagler Fjord the diabases are not at all developed. 

 At L-iiiiU l,okk at the extreme west of Grant Land were found lavas, 

 (see Bi'GiiK. p. .']."> | and these lava beds were crossed by veins of diorite- 

 porphyrite, a variety of rock that was also found farther to the soulh-

 Contemporaneous with the great igneous activity in the Post-Triassic

 have taken plan- in Klle.Miiereland since Pre-Camhrian time. Of these
