THE LIMESTONE RESOURCES OF NEW ZEALAND.

A recent publication issued by the Geological Survey Branch of the Mines Department is Part I of Bulletin No. 22 (New Series), entitled “ The Limestone and Phosphate Resources of New Zealand,” with the parenthetical subtitle Considered principally in relation to Agriculture.” The author is Mr. P. J. Morgan, Director of the Geological Survey, assisted by Dr. J. Henderson and Messrs. M. Ongley, J. E. Harris, and F. Fulton-Wood, officers of the Survey staff. The preparation of the bulletin was undertaken at the request of the Department of Agriculture, which, in the interests of the agricultural industry, desired a comprehensive report, on the limestone deposits of the Dominion. Part I of the bulletin, now published,, deals with limestone only, giving a full summary of all available information concerning the various known deposits in the Dominion, each county being dealt with, separately. Preceding this matter is a chapter of general information on the subject of limestone and lime, some extracts from which are published elsewhere in this' issue of the Journal. This part of the publication, dealing in a clear and simple manner with . the agricultural, chemical, geological, and other branches, of the subject, would in itself form an excellent bulletin or handbook of moderate compass. It is stated that Part II is to consist mainly of a general account of the plant and machinery used in the calcination and the crushing of limestone, followed by a description of the phosphate deposits of New Zealand. Part I, it may be mentioned, is a crown quarto volume of 316 pages of'letterpress, together with fourteen plates, six text-figures, and two maps, bound in quarter-cloth boards. The publication is one eminently suitable for the libraries of bodies such as farmers’' unions and agricultural associations. It may be procured from the Government. Printer, Wellington, at a price of 5s. A limited edition only has been printed.
