This piece from the Ticonderoga paper of Aug 18, 1898, reports that William and Ada were in Hague and W.R. preached a sermon at the W.M Church. The writer expressed the hope they'd build a cottage there before another year. Hague is a town on Lake George. From the other notes, it looks as if it was a popular summer resort for ministers.
The Harshaws were visiting "Capt. Mrs. Robinson". Whether she was a relative, friend, or just the hostess of the summer resort I don't know.
