VII. General Administration. 
I have already spoken of the organisation of the staff. The 
collectors are placed under the direction of the field-officers. The 
assistant-geologists are promoted, as vacancies occur, to the ranks of 
the geologists. Over these officers come the district-surveyors, who 
supervise the work of a number of geologists or assistant-geologists 
in a wide district. The district-survpyors report to their director, 
who takes general charge of the work in his own kingdom. The 
Director-General is the head of the whole organisation, and is re- 
sponsible for its conduct. He personally visits the officers in the 
field in each of the three countries, and is thus enabled to see that 
the work is being everywhere conducted on the same lines, and that 
the results obtained harmonise. It is his duty to bring the experi- 
ence gained in one kingdom to the elucidation of difficulties met 
with in another, and to decide from time to time when the surveyors 
of one branch may usefully be sent to see the work in progress by 
another branch. It will be understood that to these duties in the 
field are added the general correspondence and administration of the 
whole service, and editorial labour connected with the issue of the 
various publications. 
VIII. Relations to other Government Departments 
and the Public. 
From the beginning of its existence the Suiwey has been continu- 
ally referred to by all branches of the Government service for infor- 
mation regarding questions in which a knowledge of geology is 
required. The sinking of wells, the choice of sites for forts and 
Government buildings, the placing of graveyards, the selection of 
materials for buildings or roads, the nature of soils and subsoils with 
reference to matters of drainage — these and many other subjects have 
been reported on. Nor have the general public been backward in 
application for similar information. The offices of the Survey are 
always open, and every assistance which can be rendered to 
inquirers is placed freely at their service.
