the same general structure and mineral composition, and also that a 
straight line connecting the original locality (Green street) with the 
Griffiths street exposure passes through the centre of the second, as 
seen in the vicinity of Highland street in 1501. one is of necessity led 
to helieve that these occurrences of serpentine are merely three expos- 
ures of one and the same dike, which extends from Green street in 
a northwesterly direction.. The distance between the "Green" and 
"Griffiths" exposures is about seven-eights of a mile. That the dike 
has never been exposed between these three localities is due to the fact 
that excavations between them have not been made to a sufficient depth. 
City Engineer Frank J. Schnauber informs me that several other 
branch sewers are to be constructed within a few months in the vicin- 
ity of Griffiths street. The excavations for these, especially the one in 
Kappesser Ave., across which the dike no doubt extends, will be 
watched with great interest for new exposures. edward h. kr.\us.
