PROGRESS OF DISEASE. While we have not much definite data at hand to show just how fast the disease progresses after attacking a large tree, we have found by inoculating small seedlings and sprouts that these may be entirely girdled in one season, and from general observations on marked trees at Stamford and Middlebury it takes at least two years to kill the tree and probably three or four.

If it is attacked on the small branches these will be killed but the rest of the tree will remain healthy and in a growing condition for a considerable time. On the other hand if the infection is on the main trunk this will be girdled and the entire tree killed in a much shorter time. Certain weather conditions also apparently affect the rate of development of the fungus. DISTRIBUTION IN CONNECTICUT. At the present time the chestnut blight is distributed entirely over Connecticut. The accoimpanying maps show its spread from 1908 to 1912 and also show approximately the varying degrees of damage done in various parts of the state. The trouble is more serious in the southwestern part of the state and west of the Connecticut River. This is probably due to the fact that there is more chestnut in the western half. It was reported.
