Woodman, now that you have it cut, take 5X magnification and look at the end grain after a quick slice with a razor blade. If the bands of pores are wavy, it's elm. Elm is stringy when split. Leaves of river birch have an angled base, elm and hophornbeam, the base is inequalateral[not symetrical]. Hophornbean is small and uncommon in NJ, the wood is yellowish in heartwood IME. JinNJ
