five cents a quart
...Thoreau's Journal: 18-Apr-1859
I am looking for acorns these days, to sow on the Walden lot, but can find very few sound ones. Those which the squirrels have not got are mostly worm-eaten and quite pulverized or decayed. A few which are cracked at the small (end), having started last fall, have yet life in them, perhaps enough to plant. Even these look rather discolored when you cut them open, but Buttrick says they will do for pigeon-bait. So each man looks at things from his own point of view. I found by trial that the last or apparently sound acorns would always sink in water, while the rotten ones would float, and I have accordingly offered five cents a quart for such as will sink.
