72 SECTIONAL ADDRESSES. 



Reconnaissances and rapid surveys through the country, noting 

 specially the physiography, nature of rocks with their structural features 

 (anticlines, synclines, strike, dip, foliation, cleavage, jointing, faults, 

 dykes, and reefs), nature, occurrence and testing of minerals in rocks and 

 gravels of streams by crushing and panning. Kinds of soils, nature and 

 volumes of streams regarding irrigation and water-power, underground 

 water supplies, sites for dams and reservoirs, archaeological notes, collection 

 of rocks, minerals and concentrates, with general reports on all, and pre- 

 liminary special reports on mineral deposits and other interesting features. 



Detailed surveys and reports on particular areas, deposits and 

 occurrences, such as mentioned in the preceding paragraph. 



Special reports on the country along routes of proposed railways, 

 water-power, sanitation, and other matters. 



Assistance and advice to other Departments on geological matters. 



Surface and underground surveys of mines, with reports, maps, and 

 sections. 



Advice to mining companies and prospectors on the examination of 

 their mines, areas, and specimens of rocks and minerals. 



Assays, analyses and other determinations of samples of minerals 

 collected by the survey, or received from the public, with reports on them. 



Advice to Government regarding operations of prospectors and 

 prevention of fraudulent flotation of companies. 



Assistance to educational institutions by information supplied and 

 descriptive museum collections. 



Scientific (mainly geological and geographical) reports, with micro- 

 scopical and chemical descriptions of rocks, maps and photographs. 



Special examination of minerals in concentrates and reports on them. 



Publication of reports, maps, sections, assays, analyses, &c. 



Formation of a geological museum, mainly of practical geology, with 

 descriptions and uses of the materials therein. 



There are numbers of other kinds of geological work that need enlarge- 

 ments of the staffs of the Geological Surveys before they can be undertaken, 

 such as observations with regard to : — 



Transport of sediment and chemical character of water in streams. 

 Inland denudation, and coastal erosion. 

 Underground flow of water through rocks. 

 Decay of rocks under tropical conditions. 



Museum. — The formation of a Museum of practical geology, such as 

 that of the British Geological Survey at Jermyn Street, London, but on a 

 much smaller scale, and to have in addition local specimens, is a most 

 valuable adjunct to a Survey. It is also of great assistance to all workers 

 specially in Geology, Geography, Agriculture and Engineering, and of 

 interest to all who have any love for natural history, or wish to understand 

 something of the ground they travel over and the materials that cover it. 

 A museum of this kind should have small collections of representative 

 rocks of the great divisions grouped under (1) mode of origin, such as 

 various kinds of igneous, sedimentary, metamorphic, chemical, seolian ; 

 (2) broad general divisions of each of the groups specified in (1) ; (3) a 

 etratigraphical table showing the various chronological divisions into 

 which sedimentary rocks have been grouped, together with indications
