amage, as noevidence of any insect or animal could be found that could accountfor it, and it is most likely that the loss of twigs has no connectionwith the disease. The trees and parts of trees attacked by the fungus diseaseare readily distinguishable by the brilliant red color of the diseasedportions. Some trees have been entirely killed; others are dead intheir tops, while the lower parts of their crowns are still greenand apparently healthy; still others have occasional branchesdiseased. Trees of the last class, however, are the exception ratherthan the rule. The evidence in this matter leads us to believe thatthe disease normally works down from the top of the tree. The bark on the branches affected, and on the trunk whereit is attacked, is brownish red in color and is covered in many placeswith the fruiting bodies of the fungus which causes the trouble.The line of demarcation between the live bark and the dead barkis clear cut and distinct. The fruiting bodies of the fungus pro-

When the fungus spores havefully developed the nodules or sporophores are about one-sixteenth(iV) °f an incn in diameter and project from the bark about one-sixteenth (yq) of an inch. They are white or yellowish in color, andmay be readily seen with the naked eye. Specimens of parts oftrees illustrating the nature of the disease were sent to the StateBotanist, Dr. Charles H. Peck, and his report, which follows, diag-noses the fungus as a hitherto unknown species of Cryptosporium. These were the only balsams in the immediate vicinity; there-fore, the danger of the disease spreading is reduced to a minimum.There seems to be no regular rule governing the distribution ofthe affected trees; they are scattered irregularly amongst thehealthy trees. The lot is situated on a gentle easterly slope about fifteen hun-dred (1,500) feet elevation. The soil is a fairly rich sandy loamand is covered with a very thin layer of h
