ion, and as the printing of
such a little book frees me from the necessity of dictating the cases
to my students, I have, although somewhat reluctantly, made up my mind
to publish the present collection.

I need hardly emphasise the fact that this collection is not intended
to compete either with Scott's _Cases on International Law, selected
from decisions of English and American Courts_, or with Pitt
Cobbett's _Leading Cases and Opinions on International Law_, both
of which are collections of standard value, but intended for quite
other purposes than my own.

I have spent much thought in the endeavour to class my incidents into a
number of groups, but having found all such efforts at grouping futile,
I therefore present them in twenty-five sections, each containing four
cases of a different character. Experience has shewn me that in a class
lasting two hours I am able to discuss the four cases contained in
these sections.

I have taken special care not to have two similar cases within the same
section, for although there are no two cases exactly alike in the
collection, there are several possessing certain characteristics in
common. It is one of the tasks of the teacher and the students
themselves to group together such of my cases as they may think are
related to each other by one or more of these traits.

It has been suggested that notes and hints should be appended to each
case, but the purpose for which the collection is published is better
served by giving the incidents devoid of any explanatory matter. Should
this book induce other teachers of international law to adopt my method
of seminar work, it must be left to them to stimulate their classes in
such a way as to enable the students to discover on their own
initiative the solution of the problems.

I gladly accepted the suggestion of the publishers that the cases
should be printed on writing paper and on one side of the page only, so
that notes may be taken and additional cases added.

I am greatly indebted to Mr Dudley Ward, of St John's College,
Cambridge, my assistant, who has prepared the cases for the press and
read the proofs. In deciding upon the final form of each case so many
of his suggestions have been adopted that in many instances I do not
know what is my own and what is his work.
