Towing Past White Cliffs

We delayed setting off till 10 oClock A. M. the weather still being very disagreeable, & bad to Tow the Crafts; we then proceeded on our Voyage, and passed a white strait range of Clifts, lying on the South side of the River

Difficult Day

this day we proceded with more labour and difficulty than we have yet experienced; in addition to the imbarrasments of the rappid courant, riffles, & rockey point which were as bad if not worse than yesterday
—Meriwether Lewis

Slippery Banks

the banks and sides of the bluff were more steep than usual and were now rendered so slippery by the late rain that the men could scarcely walk.
—Meriwether Lewis

Evaporation Experiment

I found by several experiments that a table spoon full of water exposed to the air in a saucer would avaporate in 36 hours when the murcury did not stand higher than the temperate point at the greatest heat of the day; my inkstand so frequently becoming dry put me on this experiment.
