Early this year (1917) we received at our laboratory a piece of fossil wood from Mr. B. O. Wolden of Wallingford, Iowa. Wallingford is in the northern part of the state, about thirty miles southeast of Spirit Lake. Mr. Wolden secured this wood from a farmer near Wallingford. It was taken up with an eighteen inch auger drilling machine from a depth of eighty feet. Along with this wood, were found some well-preserved bits of moss, some leaves or needles which resembled spruce needles, and a very small, immature cone.
