The following table of altitudes of places in Wisconsin above the surface of Lake Michigan, may be useful in making future surveys for canals, rail roads, or other public works, and also in making a geological survey. They were ascertained by actual leveling by the author except where otherwise stated. To find the elevation of any of these places above the Ocean, we have only to add the elevation of that lake, which is 578 feet to the altitude here given. Functional parts of a foot are omitted.
