Thoreau writes in his journal:
In Stow’s sprout-land west of railroad cut, I see where a mouse which has a hole under a stump has eaten out clean the insides of the little Prinos verticillatus berries. These may be the doubtful seeds of the 14th. What pretty fruit for the mice, these bright prinos berries! They run up the twigs in the night and gather this shining fruit, take out the small seeds, and eat their kernels at the entrance to their burrows . . .
