in Thoreau’s Journal:
The strawberries may perhaps be considered a fruit of the spring, for they have depended chiefly on the freshness and moisture of spring, and on high lands are already dried up;
a soft fruit, a sort of manna which falls in June, and in the meadows they lurk at the shady roots of the grass. Now the blueberry, a somewhat firmer fruit, is beginning. Nuts, the firmest, will be the last.
