GEOLOGICAL SECTION 



Report of the Section for the Year Eading 

 May, 1907. 



The Chairman and members of the Geological Section 

 herewith beg to submit their annual report ending May 1907. 



The Section, in submitting this report, has much pleasure

 active members again resumed the work during the winter 

 months of comparing specimens and relegating them to their

 to cover the ground, there has been a large number of fossils 

 collect<^d, many of which have been sent abroad to the differ- 

 ent museums where these gifts are appreciated, and not a few 

 have been added to our own museum. Colonel C. C, Grant 

 has been devoting much of his time in search of rare grapto- 

 lites and fossil sponges, and his endeavors in that direction 

 have been abundantly rewarded. He has discovered what 

 appears to be the root-like attachment of that species of 

 sponge which has always heretofore been regarded as a free, 

 or of the floating variety. He also found some beautiful 

 specimens of graptolites which are new to science. There 

 appears to be a peculiar circumstance connected with this 

 form of pastcoulor palaeozoic life which has not, so far as I am 

 aware, been alluded to by any collector, that is that these 

 graptolites appear to have been gregarious, and ha4 existed in
