3. West Virginia Geological Survey County Reports and 

 maps. Ohio, Brooke and Hancock Counties; by G. P. Grims- 

 ley, Assistant State Geologist. Introduction, by I. C. White, 

 State Geologist. Morgantown, West Virginia, 1907. Pp. xxix + 

 378, with 16 plates and 37 figures ; 8 maps in accompanying 

 atlas. — This volume is mostly economic in character, containing 

 studies of the coals, petroleum, natural gas, clays, stones, climate, 

 and soils of the Panhandle area. In addition a chapter is 

 devoted to the historical and industrial development of the Pan- 

 handle counties and another to the physiography of the same.

4. Geological map of the Colony of the Gape of Good Hope, 

 sheet XL VI. Published by the Geological Commission, 1 907. 

 Geology by A. L. du Toit. — The area covered by this map is a 

 square degree immediately northwest of Kimberley ; the map is 

 published on a scale of 1 : 238,000 or about four miles to the 

 inch. The region is underlaid by the older Paleozoic series of 

 diabases, amygdaloids, volcanic breccias, and tuffs of the Ven- 

 tersdorp system, these strata outcropping on the east. Into them 

 the Vaal river has cut a deep gorge. On the west this basal 

 eruptive system is covered by dolomites, limestones, cherts and 

 shales of the Campbell-Rand series, forming the Kaap plateau. 

 Between the two and occupying depressions in the volcanic 

 series occur broad areas of the Dwyka system of Carboniferous- 

 Permian age. Sheets' of diabase which were formerly intrusive 

 in the Dwyka are now broadly exposed as high plateaus within 

 those areas. j. b.

 3 (New Series) New Zealand Geological Survey. Pp. x + 111 

 with 26 plates, 2 figures, 11 maps, 7 cross-sections. — This report 

 deals with the geology of a district facing Golden Bay, lying 

 consequently in the extreme northerly portion of the South 

 Island of New Zealand. The particular economic interest of the 

 region centers in the deposit of iron ore, though coal and metal- 

 liferous deposits are also present. The region is of mountainous 

 character and extremely wild but stands in marked contrast to 

 the bolder and more magnificent scenery of the Southern Alps. 

 The geological formations of the district comprise a basement of 

 highly metamorphic rocks of Ordovician age, or older. Upon 

 these are laid down argillites, grauwackes, and quartzites of Ordo- 

 vician age ; then the Haupiri series of conglomerates, breccias 

 and argillites of later Paleozoic age. Upon these were deposited 

 Miocene sediments, the lower portions holding coal and the whole 

 still nearly horizontal. 



Physiographically the i*egion consists of an old mountainous 

 land of pre-Miocene formations which had probably been ma- 

 turely dissected prior to Miocene times. The mountains are sur- 

 rounded by an upland country which was once entirely, and
