July TELESCOPE 146 Meetings Bus iness Meeting Friday 28 August 1964 Dossin Museum, 8 p.m. Visitors are welcome to these meetings of the Board of Directors. General Meeting Friday 25 September 1964 Dossin Museum, 8 p.m. Our speaker will be Mr. F. Wells Robison, Technical Liaison Officer of the United States Lake Survey. The program will be their latest film, "The Lake Survey." We have all been familiar with earlier instruments and work of the Lake Survey through viewing the display at Dossin Museum. The waters which they chart have been much in the news for their unusually low levels, making shallower the dredged channels for shipping and bringing hardship to property along the shoreline. What might be considered normal levels for the lakes? Is there any truth in the idea that high water levels on the lakes come in cycles of seven years? Bring these or other questions with you, and learn how the Lake Survey does its work today. Our cover shows Boland & Cornelius' John T. Hutchinson, newly converted to a seIf-unloader at Fraser-Nelson in Superior, Wisconsin. She is also of interest to readers of our feature article, for she is one of the six Lorain-built Maritime Commission lakers equipped with four-cylinder compound reciprocating steam engines (together with the ten lakers built by Great Lakes Engineering Works and given triple-expansion engines, this class of 1943 had the last conventional reciprocating steam engines given to lake freighters). Our photograph is by Peter Worden, who informs us that the new self-unloading boom fitted to Richard J. Reiss at Manitowoc is identical, but painted black. Below is his photograph of car ferry Ann Arbor No. 7, upbound in the St. Marys River. She was bound for the Fraser-Nelson yard at Superior for a nearly $2 million rebuilding. Ann Arbor No. 7 will trade her twin triple-expansion steam engines for diesel-electric propulsion with pilot house controls. She will also have her upper decks raised to give clearance for higher railroad cars. Sometime before the Soo Locks close for the winter, Ann Arbor No. 7 is to return to Lake Michigan, rebuilt and possibly renamed Viking to honor the settlers of Wisconsin, Northern Michigan and Minnesota.
