lO DR. EGBERT BELL : 



divisions may become recognised as two separate series, subordinate to the Hurouian 

 System, which should retain the name as a whole ; but I do not think it would ever be 

 desirable, even if it should prove possible, to form out of these rocks a new system of equal 

 rank with the Hiironian. It would be equally undesirable to attempt to introducn^ a new 

 name to take the place of one so well established, so appropriate and so universally 

 recognised. Still, we are indebted to Prof. Irving for having called attention to the 

 question, and his criticisms will, no doubt, stimulate fresh research in this direction. 



lu regard to the correlation of the Hurouian and the Animikie, I am not aware if 

 Prof. Irving still holds the view that they form parts of one series. Around Thunder 

 Bay the Animikie rocks are certainly very different in almost every respect from the Huro- 

 uian, as there described under that name by Logan, and they rest on the almost vertical 

 denuded edges of the latter, nearly horizontally. This subject was very ably dealt with 

 by Mr. Peter McKellar, in a paper read at onr last meeting and published in the volume 

 of Transactions which has since been issixed. I need not, therefore, occupy further space 

 with this question. 



I should like, however, to call your attention to a few points in connection with the 

 relations of the Hurouian to other rocks which have not yet been recognised as forming 

 parts of it, and which haven ot hitherto been much discussed. On the east coast of 

 Hudson Bay at Little Whale Eiver and Richmond Gulf may be seen a great thickness of 

 hard, grey and red conglomerates, in which rounded pebbles of white quartz are conspi- 

 cuous, associated with hard red and grey sandstone. Similar rocks are also largely 

 developed in the eastern part of Lake Athabasca and on the north arm of G-reat Slave 

 Lake. They are also said to occur on the upper part of the Clearwater River. On the 

 east side of Hudson Bay, these conglomerates and sandstones clearly lie between the 

 Manitoun^^ck (believed to be the equivalent of the Animikie) and the Laurentian, and 

 in one place green rocks, like Hurouian, appear to intervene between them. 



Under the microscope, the Hurouian greywackes of Lakes Temiscaming and Tinna- 

 gami, and the country thence to Lake Huron, bear a strong resemblance to those which 

 form so large a i^ropoiiion of the boulders and pebbles of the drift around and south- 

 westward of Hudson Bay aad James Bay, and a similar rock appears to occur iti situ on 

 Long Island, off Cape Jones. Prom the abundance of these pebbles and boulders all 

 around James Bay, and especially to the west of it and considering the immense extent 

 of country over which they are spread in that direction, there appears to be little doubt, 

 that the formation from which they have been derived is largely developed irnder the 

 waters of the bay. A somewhat similar rock, which also resembles the gold-bearing 

 " whinstone " of Nova Scotia, is met with dipping at considerable angles at the mouth of 

 Churchill River and along the coast in the neighborhood. 



The present controversy as to the Huroniau rocks and the proposal to separate a part 

 of the system from the main body, is largely due to the fact that the locally developed 

 quartzites happen to be so conspicuous in the easily accessible region on the north shore 

 of Lake Huron. But it must be remembered that similar c[uartzites are found in this system 

 in many other regions. The white quartzites of Marble Island, which are at least as 

 conspicuous as any of those near Lake Huron, are associated with dark, hydro-mica schists ; 

 and similar rocks are reported as abundant far into the interior on the north-west side of 

 Hudson Bay. "West of Lake Superior, grey quartzites are found along the international
