The experiments wiih cut twigs, covered with glass tubes, were repeated on the tree in the center, with the same result as before. Attempts were made to introduce the fungus into various buds and young twigs near the top of this tree without wound- ing the bark, but none of them were successful. The tree on the left was treated on April 5 in the same way, several buds and young twigs from one to five inches in length being covered with the fungus for some time under glass ; but all these attempts likewise failed. The dead branch at the top was inoculated through a wound. chestnut trees within his jurisdiction appear to be dying rapidly.
