Workmen digging a well at the elevator during April, 1896, came to a forest bed at a depth of eighty-five feet below the surface. Quite a number of pieces of wood were removed, one being a branched log, eight inches in diameter and five or six feet in length. Three pieces were secured by the writer and microscopic sections made of the wood revealed the border pits, characteristic of conifers. The materials passed through above the forest bed were composed of yellowish and blue clay charged with usually small pebbles. A 425-foot well drilled by the city, two blocks north of the elevator, has left only an obscure record. The only data of interest preserved were the facts that the limerock was 200 feet below the surface, and the materials passed through above were clay and gravel.
