No. 273. THE ANNA, the first boat ever launched upon the lake. Its frame-work was brought up from Fort Ellis and then put together, and covered with tar-soaked canvas. A tent-fly made the sail. In it two adventurous members of the survey visited every arm and nook of the lake, and made all the soundings. It is so named in compliment to Miss Anna Dawes, a daughter of the distinguish statesman whose generous sympathy and aid have done so much toward securing these results.
