During a recent journey through northeastern Missouri, the writer noted some interesting experiments on the grounds of the University at Columbia, Mo., under Prof. Hussman's care, in regard to evergreens, and indeed other trees, the result being that trees with numerous surface fibres, such as hemlock spruce and Norway maple, did not succeed nearly as well as those species which were deep rooting. Of course this fact will require more care in transplanting, as trees with a few long sprawly roots never move as easily as those with an abundance of fibres. The deep rooting trees seem better able to stand the heats and droughts of summer, and the excessive evaporation from high wintry winds than the others.
