CANADA. 351 



this zone belonged to the Lower Laurentian. (Quart. Jour. Geol. Soc., 

 18G7, XXllI. 253-257.) 



In the same paper Mr. H. G. Vcnnor gives a section of the Hastings 

 series in ascending order ; this is here given, abbreviated by the omission 

 of the descriptive portions. 



1. Red felspathic strata. 



2. Dark -green chlorite slates. 



3. "Whitish highly crystalline limestone. 



4. Gray silicious or fine micaceous slates. 



5. Bluish and greyish mica slates. 



6. Grey and pinkish dolomite. 



v. Grey micaceous limestone or calc schist. 



8. Green diorite-slates. 



9. Reddish granitic gneiss. 



In the Report of Progress for 1866-69, Mr. Vennor again furnishes a 

 section of the rocks of the Hastings series, referring to the one given 

 above, quoted from the Quarterly Journal of the Geological Society, and 

 using the -words " it is here repeated." ('. c, p. 144.) 



The following is the section as given, in ascending order, in the 

 Canada Report : — 



Lower Division. A. 



1. A great mass of highly crystalline syenitic rock. 



2. Reddish and flesh coloured granitic gneiss. 



3. Greyish and flesh-colom-ed gneiss. 



4. Crystalline Hmestone, sometimes magnesian. 



Middle Division. B. 

 1. Hornblendic and pyroxenic rocks. 



Upper Drvisiox. C. 



1. Crystalline and somewhat granular magnesian limestone. 



2. Gray siUcious or fine-grained mica-slates. 



3. Bluish and grayish micaceous slate. 



4. Gneissoid micaceous quartzites. 



5. Grey micaceous limestone- 

 Comparison of the sections given by Mr. Yennor will show that there 



is hardly any resemblance between the two. No one would ever sup- 

 pose, unless previously informed of the fact, that the same rocks were 

 uitended to be embraced in them. Particular notice may be called to 

 the transference of No. 8 of the first section from near its summit to the 

 middle of the series in the second one.
