CHESTNUT BARK DISEASE. 379 
not find any one that wanted cordwood that had been split and 
stacked while clearing part of the property three years ago.” 
The type of damage so far mentioned, however, is incon- 
Spicuous in this state as compared with the loss that occurs 
through the death of trees which are not yet fit for commercial 
purposes and can be used only for cordwood. The market for 
the latter in certain districts is easily satisfied. This means low 
prices or long storage. The greatest loss is caused where future 
profits are entirely cut out by the death of half grown 
trees and sprout growth too small for present use. If the 
disease progresses in the future as actively as in the past, the 
prospects of our chestnut forests are very poor indeed. This 
means serious loss, for the chestnut is one of the most useful 
forest trees in all parts of the country where it occurs. 
Besides’ the loss from a commercial point of view, there is 
the damage caused to the shade and ornamental trees, and to 
groves kept on estates, parks, etc., for aesthetic rather than 
practical purposes. To estimate the damage here is impdssible. 
In the United States. Certain. writers have attempted to 
estimate.in money value the loss caused by the blight. Just 
how this loss is estimated is not made very clear. To the 
writer it seems to be largely guess work. However, it is 
interesting to note these figures in order to compare them with 
losses given for other fungous diseases and insects. Maurrill 
(49) in 1908 estimated the damage in and about New York 
City between five and ten million dollars. Mickleborough (40) 
about the same time estimated the damage through the country 
at not less than ten million dollars, while in 1909 he (41, p. 14) 
wrote: “The damage already done in the states of New York, 
Pennsylvania and New Jersey, would not be less than twelve 
million dollars.” Metcalf and Collins (38) gave twenty-five 
million dollars as a conservative estimate of the financial loss 
to the country up to 1911. Detwiler (19, p. 130) estimates the 
loss in Pennsylvania alone as ten million dollars, allowing seven 
million for forest and three million for ornamental trees. The 
largest estimate that we have seen is that given by Marlatt 
(31, p. 345), who said in 1911: “It is estimated that the loss 
in and about the City of New York is now between five and 
ten million dollars, and the loss throughout the area now 
infested is fully one hundred million dollars.”
