commercial usages, and also cartographic scales, conventional economic
 signs, colours, quantities, and units of value, diagrams etc.
This will require reference to past experience and logal considerations,
 and it will thus be necessary;
c) to make a study of the principles underlying the question,
from the point of view of history and social legislation comprising
the various periods of development of the mining industry, systems
of laws relating to land and mining, methods of exploitation, cartels
 and trusts and systems of socialisation and nationalisation.
The Committee would have, in the second place, to concern
itself with practical aims and duties, namely,
a) the actual international adoption and simplification of scientifically
 defined principles, with the assistance of the great organising
machinery of the League of Nations.
b) as a regular practical duty: to follow movements of the markets
 and to cope with crises.
c) as an occasional duty: to prevent disputes, to give expert
opinions, arbitral awards etc,
In the third place, in order to carry out the two duties mentioned
above the Committee would naturally have to concern itself with
the collection of the necessary material and the publication of results.
This grouping of facts on the basis of a scientific method with unbiassed
 objective deductions tending towards practical objects, in
short, this rational synihesie of a number of analytical details represents
 a task which can only be accomplished by a world organisation
 such as is to be found in the idea of the League of Nations
and of international intellectual co-operation.
An international mining institute such as this, however, acting
in the interest of economic peace, can by means of its scientific
and practical activities and with the aid of serious publications and
suitable propaganda, prove a most powerful factor in the cause of
peace,
