Variations in Great Lakes Levels

Detroit: Corps of Engineers U. S. Army Great Lakes Division, February 1952. Paperback. 33p., photocopied from typescript, plus four huge folded "figures" (= maps & charts), softbound standard leaves under professionally-printed cover sheets and black binder's tape spine. Bears an ownership signature and, laid in, a TLs from the executive officer; lakeshore property owners and other parties were evidently concerned with high tides. Two of the charts are slightly misfolded and stick out a little, as does the TLs laid in; in general a very good copy.
