There is a road from the Friends' Settlement nearly completed, across the country to Genesee river, forty-five miles. I went from Geneva to Canadaqua, sixteen miles, crossing the outlet of Canadaqua lake, just as I entered the town. This is a settlement made by Mr Phelps, and promises to be a very flourishing one ; there are now about thirty houses situated on a pleasant slope from the lake, and the adjacent farms are very thriving. The Indians are settled on all the reservations made by this state, and are to be met with at every settlement of whites, in quest of rum I From Canandaqua I travelled about twenty six miles through a fine country, with many settlements forming ; this brought me to Genesee river. On this river a great many farms are laying out ; sixty-five miles from its mouth is a town marked out by the name of Williamsburgh, and will in all probability be a place of much trade ; in the present situation of things it is remote, when considered in a commercial point of view ; but should the fort of Oswego be given up, and the lock navigation be completed, there will not be a carrying place between New-York and Williamsburgh. The present carrying places are as follow, viz. Albany to Schenectada, sixteen miles -- the Little Falls, on the Mohawk river, two miles -- from the head of the Mohawk to Wood creek, one mile -- Oswego Falls, two miles -- Genesee falls, two miles. Thus you see there is only twenty-three miles to cut and lock, in order to carry commerce by water, through an extent of country, capable of maintaining several millions of people. The famous Genesee flats lie on the borders of Genesee river ; they are about twenty miles in length, and about four miles wide ; the Soil is remarkably rich, quite clear of trees, and producing grass near ten feet high.
