there is no evidence of unconformity between the Bunter and 

 Permian ; and that the " Permian " sandstones, while they 

 probably include strata of Upper Permian age, are in the 

 main considerably older, and possibly the equivalents of the 

 Keele Sandstones (Upper Coal Measures) of North Staffordshire. 

 The courses of several large faults have also been satisfactorily 

 determined. 



In the Oamaru district, North Otago, New Zealand, fully 

 described by Prof. J. Park (Geol. Surv. N.Z., 191 8, Bull. No. 

 20, pp. 119), the oldest rocks are Early Palaeozoic phyllites 

 and mica-schists. On these basement rocks rests a great 

 succession of Middle Tertiary strata. The lowermost beds are 

 lignitic measures of quartz gravel and sand. Overlying them 

 conformably is a great marine series with which are intercalated 

 beds of volcanic mud and ash, and flows of basalt lavas. Some 

 of the latter have the pillow form well developed as shown 

 in an excellent photographic illustration.

The Sooke and Duncan area (Vancouver Is.), described by 

 C. H. Clapp (Geol. Surv., Canada, 191 7, Memoir 96, pp. 445) is 

 a greatly dissected plateau of deformed Carboniferous and 

 Lower Mesozoic rocks, invaded by granite batholiths, and 

 then covered unconformably by a great series of Upper Cre- 

 taceous and Tertiary sediments and lavas. These rocks in 

 their turn were folded, and invaded by small stocks of gabbro, 

 which have differentiates of granite and anorthosite. 



T. T. Quirke describes the Espanola district of Ontario, 

 which forms part of the eastward continuation of the original 

 Huronian area of Logan. For the most part the rocks are of 

 Huronian age, with some older basement rocks consisting of 

 highly metamorphosed sedimentary schists and slates, with 

 intrusive granites and greenstones. These are equivalent to 

 Coleman's Sudburian Series. The district is characterised by 

 extensive thrust faulting (Geol. Surv., Canada, 191 7, Memoir 

 102, pp. 92).
