The Stone Picker Appears on the Farm. This is one of the first stone picking machines to make its appearance in the potato region of Maine. The invention is expected to be of considerable aid to farmers who have been compelled, in the past, to pick up stones by hand in the cultivated fields. It can gather stones at the rate of 12 tons an hour.
