 pp. 125, 126. The outcrop is on the W. shore near C. Liptrap ; and the 

 limestone appears to be conformably overlain by ferruginous sandstone. 

 It is a crystalline, granular, black and white mottled and veined 

 marble, suitable for ornamental purposes : probably U. Silurian.

Travers, "W. T. L. Notes on Dr. Haast's supposed Glaciation of 

 'New Zealand. Trans. iV. Zealand Inst. vol. vii. pp. 409-440 ; 

 Proceedings^ p. 497. 



Inquires into and controverts the views of Dr. Haast. The views of 

 the two writers coincide on one point only, that the glaciation took 

 place with an elevation of the land. Mr. Travers considers it to have 

 taken place at the close of the Miocene, and to have continued during 

 great part of the Pliocene period ; whilst Dr. Haast believes that the 

 islands of N. Zealand were submerged during and until the close of the 

 Tertiary epoch, the glaciation commencing coincidently with the re- 

 emergence of the land. Again, the author thinks that the glaciation 

 was such as would occur in the latitude of New Zealand, in a range of 

 mountains averaging 14,000 feet in height, whilst Dr. Haast com- 

 pares it to the present condition of Greenland. The two writers differ 

 also as to the origin of this glaciation and its subsequent disappear- 

 ance. One of the chief points brought forward as antagonistic to Dr. 

 Haast's view of the extreme glaciation is the absence of boulder clay 

 or till resembling that found in many parts of Scotland, &c. R. E., Jun.

 The Auriferous Reefs, except those at Portobello, are in metamor- 

 phic schist, argillaceous mica-schist, or phyllite, changing into mica- 

 schist, rich in interlaminations of quartz. They differ in structure 

 and mode of development, and are classed in 6 groups: — 1. True 

 lodes, promising permanency in depth, and resembling the "Block 

 Eeefs " of Victoria. 2. Reefs not of solid quartz throughout, but of 

 blocks of quartz and *' mullock " intermixed. 3. " Quartz -mullock
