EIGHT years ago, when the chestnut blight (Endothia parasitica) began seriously to menace my native chestnut forest, situated in the towns of Stamford and Greenwich, Conn., notes were made upon the subject and a number of varieties and species of chestnuts were added to the collection. At that time there were about five thousand old American chestnut trees {Castanea americana) upon my country place; there were also half a dozen chinquapins (Castanea pumila) about five years of age, and a few grafted trees of named varieties of chestnuts which had been purchased from nurserymen at about the time when the chinquapins were purchased. There were two saplings of Castanea mollissima, the Chinese chestnut, which had been given me by Professor C. S. Sargent.
