GEOLOGY OF CENTRAL OTAGO.

From the Department of Mines, *We?< lingfton, we hat© received a copy of Bul< letin No. 5 (New Series) of the New" Zealand Geological Survey. It deals witj( the geology of the Cromwell subdivisioiW Western Otago division, and ie, in fact? the record of work done in that district by Professor James Park, Director of the Otago University School 'of Mines, aiid hia assistants during the field seasort 1906-7. From a prefatory synopsis of the 1 contents we learn that "the area dealt with in this report extends from Benddgoi to Cromwell, and from Cromwell to Bannockburn, and thenoe along tho valley ofi the Kawarau to Gibbston, Double ConeY Crown Terrace, and the headquarters o5 Soho Creek. It includes the wjet side oS the Dunstan Mountains, the eouth-westi half of Pisa Range, the north-east eide oE Carriok Range, and the north end of the Remarkables, embracing within its limits' th& survey districts of Wakefield, Cromwell, Bannockburn, Crown, and Kawarar,in the Otago Land District." The bulletin is accompanied by 10' excellent larga scale maps and six sheets of sections.! It also includes numerous diagrams ami plates, -several of the latter showing extended views of the great* mining claims within the- district. The mere laymani stands appalled before a solid record oS 6peciad work in physiography, general and? economic geology, and petrography such aa this. It is not easy to conceive how, in, the moderate time available, an amount of work co great could 1 have been accomplished. Of the importance of the work itself there can be no question. The,' purely scientific aspect has its own value> but the economic significance will appearstill greater to many. Both are of real importance, and both, we may confidently, assume, will find future advance made more readily attainable by help of such! garnerings of knowledge as are here set forth in systematic order.
