14 THE HAMILTON ASSOCIATION. 
REPORT OF GEOLOGICAL SECTION 
For the Year Ending May, 1904. 
The Section, in submitting this report, has much pleasure in 
informing the members of the Hamilton Scientific Association that 
the usual interest has been maintained and much: work has been 
done by the members of the Section during the year which has just 
closed. 
Many specimens have been added to the already large collection 
of Silurian fossils in the Museum of the Association, by Col. C. C. 
Grant and others. 
Col. C. C. Grant has made the discovery of several new varieties 
of Graptolites, which have been sent to different recognized authori- 
ties upon these obscure forms of life which existed in the ancient 
seas of the Silurian period, also some new Gastropods, which have 
been sent away for identification and classification. Although the 
season covered by the period from May to November for the collec- 
tion of the fossil sponges was not as favorable as some previous ones, 
yet a considerable number of these unique fossils were obtained and 
distributed to different parts of the world. The Barton beds in the 
vicinity of Hamilton have become famous for the number and variety 
of specimens obtained from them, and they are frequently alluded 
to by writers of the life history of the fossilized sponges. The 
thanks of the Hamilton Scientific Association is due to Col. C. C. 
Grant for his indefatigable zeal in the pursuit of the collection of 
specimens and for sending them to so many Museums, thereby being 
instrumental in publishing to the world this fruitful field of the fos- 
silized remains of the homes of the Amoeba. 
Letters have been received from the Directors of different 
Museums expressing their thanks to the Council for specimens sent 
them by one of our members, Col. C. C. Grant: Dr. Ray Lancas- 
ter, of the British Museum ; Prof. J. F. Whiteaves, of Ottawa; Prof.
