PRESENT STATUS OF CHESTNUT BARK DISEASE. 53 
States have suffered from a disease during the past twenty years, 
since, as already stated, that is a totally different thing from the 
bark disease. 
Where the bark disease is already firmly established and has at- 
tacked 50 per cent or more of the chestnut trees, as in the vicinity of 
the city of New York, it is probably too late to try to do anything, 
but where the disease is just appearing there is no reason to doubt 
that strict quarantine methods will apply as well to this as to any 
other disease, whether of plants or animals. The question to settle is 
simply which is more costly—to use the methods recommended or to 
lose the trees. The people concerned must decide.
