GEOLOGICAL NOTES. 



Read at the opening meeting of the Geological Section, Noveinbei- 2^th, i8g8. 

 BY COL. C. C. GRANT. 



Although it has been usual at our opening meeting in preceding 

 years to bring to the notice of its members any fresh matter regard- 

 ing the field geology of the district, I have, however, been requested 

 to defer calling attention for a little while yet, for certain reasons, to 

 this subject. The suppression of the matter is only temporary. 

 The silence is enjoined on the writer's part for a brief period, until 

 necessary arrangements are completed. (The foregoing refers to a 

 recent discovery here of Bog Iron Ore.) 



A few years ago a small pond (dry in autumn) was deepened 

 and cleared out for the purpose cf holding a sufficient supply of 

 water for the cattle on the farm. In the muddy material thrown 

 aside from the excavation were a few large boulders seemingly, 

 which, on closer examination, proved to be Bog Iron. 



From the limited extent of the swampy portion of the field the 

 writer considered it was very doubtful if the deposit could ever be 

 turned to profitable account. 



The adjoining land has been cultivated for some time, and the 

 natural depressions on the surface, partly filled in, he was unable to 

 form a clear idea of the original extension of the swamp now drained. 

 Near a slight surface depression a considerable heap of apparently 

 Northern boulders — relics of the great Ice Age — had been noticed 

 years ago. Only recently this heap, on closer examination, proved 

 to be Iron Ore, which had been evidently mistaken for erratic rocks 

 and placed there, as is customary here. About two cart loads of 

 the material is now exposed. A more extensive chain of boggy land 

 has been remarked in a forest adjoining. No doubt this contains 

 the mineral also, yet this cannot be positively stated without its 

 being tested. So we may be content to state there are undoubted 

 indications of Bog Iron existing near Hamilton, close to a good 

 stone road and railway.
