As requested by Section IV, at the last meeting of the Eoyal

(1) Adams, F. D. — ^The report is accompanied by a geological map and a brief 



description o^ the region. The wells are situated in flat-lying palaeozoic .

 channels resulting from the solvent action of the waters acting along 

 joints, bedding planes and ci-acks in the limestone beds. 



(2) Bailey, L. W. — A review of the known occurrences, within the province, of 



rocks of volcanic origin. The great periods of volcanic activity were 

 the Huronian, Silurian, Lower Carboniferous and Trias. The " typical 

 volcanic rocks of the Pre-Cambrian (Huronian) system are diorites 

 and diabase ; those of the Silurian, felsitic and porphyritic rhyolites ; 

 those of the Lower Carboniferous, dolerite, and those of the Trias, 

 basalt."
