How river water carries and deposits sand and silt
Where the current slows or meets thickets it drops finer silt and heaps of sand
Pen notes written over faint red-chalk figures of riverbanks set out rules for how flowing water sorts and deposits sediment. Materials lighter than sand settle toward the low part of the river, finer silt or sand collects where the water moves least, and turbid water depositing among low thickets drops much sand where its eddies revolve. A small range of mountains is drawn in pen across the top of the sheet, above the water notes; further untranscribed text may be present in the closely written page.

Slower water lays down finer silt
Where the water has less motion, the note states, the surface of its bed will be of finer silt or sand; and things lighter than sand come to rest toward the low part of the river beneath the start of the wave's decline.
Eddies among the thickets deposit sand
Where the course of turbid water enters among the low branches of the thickets, the many revolutions of the eddies unload much sand or silt, forming the heaps of sand on the riverbed named in the heading.
Mountain range sketched above the notes
A small chain of mountains is drawn in pen across the top of the sheet, above and separate from the water and sediment notes. It is not covered by the transcription.
