THE LEAGUE OF NATIONS 471

ARTICLE 18.—Every treaty or international engagement en-
tered into hereafter by any Member of the League shall
be forthwith registered with the Secretariat and shall
as soon as possible be published by it. No such treaty
or international engagement shall be binding until so
registered.

ARTICLE 22.—To those colonies and territories which as a
consequence of the late war have ceased to be under the
sovereignty of the States which formerly governed them
and which are inhabited by peoples not yet able
to stand by themselves under the strenuous
conditions of the modern world, there should be applied
the principle that the well-being and development of
such peoples form a sacred trust of civilisation and that
securities for the performance of this trust should be
embodied in this Covenant.

The best method of giving practical effect to this principle
is that the tutelage of such peoples should be entrusted to
advanced nations who by reason of their resources, their
experience or their geographical position can best undertake
this responsibility, and who are willing to accept it, and that
this tutelage should be exercised by them as Mandatories
on behalf of the League.

ARTICLE 23.—Subject to and in accordance with the provi-
sions of international conventions existing or hereafter
to be agreed upon, the Members of the League:
(a) will endeavour to secure and maintain fair and
humane conditions of labour for men, women, and
children, both in their own countries and in all
countries to which their commercial and industrial
relations extend, and for that purpose will es-
tablish and maintain the necessary international
organisations;
