Résumé

This a presentation of an empirical method of determining the usual (or mean) high water line on both beach and rock shore line. Evidence is presented as proof of the accuracy of the method, and mention is made of the consistency of results when the method is applied. Because the criteria are based on a combination of photographic tom, texture, alignment patterns and small indistinguishable object images and their shadows, it is claimed to be applicable to most circumstances. A ll the criteria may not be present. Selection of the few illustrations is based upon proximity of beach and rock shore lines with additional evidence in the vicinity presented for verification of the conclusion. The area has been independently compiled from prints of the same exposures a sufficient number of times to afford a check on consistency of interpretation. The above conditions have ilimited the selection of illustrative material. The illustrations are believed to offer about average difficulties. The text contains the keys to letters and numbers which appear in the illustrations.
