Excerpt from Methods of Investigation of Tides and Currents: A Review of the General Methods Adopted, in a New Field of Investigation, by the Tidal Survey of CanadaBench Marks have almost always been established both at the principal and secondary stations, even when tidal observations have only been continued for a few months. These are valuable at present for local reference, and will be more so in future, when they are con useted together by some general system of levels. The Bench Marks thus established along the St. Lawrence and throughout the Maritime Provinces, are described in a Paper communicated to the Canadian Society of Civil Engineers The extreme levels of high and low water in the various harbours are there given, as well as the tide levels at the head of the Bay of Fundy, which are valuable for the security of the extensive hay lands in that region, known as dyked marshes.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
