Verry foggy this morning. Thermometer 63° Ferrenheit, immersed the Thermometer in the river, and the murcury arose immediately to 75° or summer heat so that there is 12° difference is sufficient to shew the vapor which arrises from the water; the fogg this prodused is impenetrably thick at this moment; we were in consequence obliged to ly by untill 9 this morning Mr. Gui Briant [1] arrived with two boats loaded with firrs, he informs me that if I can reach, and get over the George-town barr 24 miles I can get on; this is some consolation. we set out at 9 this morning and passed a riffle just below us called Atkins's got over with tolerable ease passed the mouth of big bever creek [2] and came to ancor off Mackintosh [3] being 2½ miles— discharge one of my hands.— passed the riffle below Mackintosh.— about three miles from this we stuck on another riffle the worst I think we have yet passed were obliged to unload and drag over with horses.— staid all night having made only six miles.— [4]
