state the problems which still remain to be solved, and something of their relative importance. They will bring out the scientific and economic advantages which have resulted, directly or indirectly, from the surveys already executed. They will indicate the general scope of the more important publications, both cartographic and textual, which have appeared, and while they are not intended to be bibliographic primarily, they will contain references to the more important publications and to such bibliographies as may have been compiled. In some cases, at least, they will give the cost of the work which has been accomplished. The plan also involves a series of articles on the surveys in foreign countries. It is hoped and believed that these papers will be of much value. A considerable period of time will necessarily elapse before the series is completed, but in the end it is believed that it will constitute a valuable compendium of geological work throughout the world.
