6:30 A. M. - River thirty-four and an eighth above summer level, or fallen about four inches since evening of 15th. It flows now (a sunk bottle) one hundred feet in two minutes at boat’s place, there being no wind.
P. M. - Up river.
Pontederia seeds falling.
See a flock of eight or ten wood ducks on the Grindstone Meadow, with glass, some twenty-five rods off, - several drakes very handsome. They utter a creaking scream as they sail there, - being alarmed, - from time to time, shrill and loud, very unlike the black duck. At last one sails off, calling the others by a short creaking note.
