The October 2009 issue of Cape Cod Life has a lovely article on the modern cranberry harvest. Before they flooded the cranberry bogs creating the glorious sea of red berries, the harvest involved back-breaking work with pronged wooden baskets.
In the early 1900’s, this mother and two children (photo below) would pick about 40 measures a day at 7 cents a measure. See the scoops and pail in the foreground. There were two out of eighteen workers under the age of 12 at the bog that day. They would be expected to work several weeks more and probably miss a bit of school before the harvest ended.
