This new treaty edition is to be entitled Treaties and Other International Acts of the United States of America. The title requires some explanation as to its extent and limits. Agreements or acts which have gone into force are, with certain exceptions noted hereafter, included in the volumes of this edition now to be considered. Unperfected treaties, to use the current expression— agreements which have not gone into force—are in general, therefore, and subject to the exception mentioned below, excluded. It is to be observed that in a broad sense “unperfected treaties” include those which have been definitely rejected as well as those which are to be deemed pending; and there are also a few instances where an agreement was not formally acted on but is so ancient as to be obsolete. All those unperfected treaties, however, of whatever classification, are here omitted, with the exception of such of them as may be within one group of documents now to be mentioned.
