143) states in June, 1906: ‘‘ The same disease has been found to exist 
among the chestnuts of New Jersey, Maryland, and Virginia.” As to 
the authenticity of the records in Maryland and Virginia at this date 
the writers of this bulletin are in doubt. 
Murrill (1906 b:203, 207) states in September, 1906: ‘“‘I now know 
of very few chestnut trees in this portion [Bronx] of the city that appear 
to be worth trying to save and I do not consider any immune’”’; and 
further: ‘‘ Mr. Levison reports all the chestnut trees of Forest Park, 
Brooklyn, to be either dead or dying, and many in Prospect Park to be 
seriously affected. Wherever he has found the chestnut tree in Brooklyn, 
he has found the disease.” 
Metcalf (1908 a:5s5) states in February, 1908: ‘‘ The bark disease.... 
is now reported from Connecticut, Massachusetts, Vermont, New York 
as far north as Poughkeepsie, New Jersey, Pennsylvania, and possibly 
Delaware.” In the same month Murrill (1908 a: 26) reports approxi- 
mately the same distribution, and adds Maryland to the list. Clinton 
(1908:345) reports that the disease has become common in the neighbor- 
hood of Stamford, Connecticut. Hodson (1908: 4-5), after giving more 
nearly exactly the location of diseased areas in each State, sums up the 
situation thus: ‘‘ The range at present, then, includes eight states, 
Connecticut, New York, New Jersey, Pennsylvania, Delaware, Maryland, 
Virginia, and Massachusetts.” Mickleborough (1909) reports the presence 
of the disease in six counties in eastern Pennsylvania, and Clinton (1909: 
881-885; 1911: 716-717; 1913:371-372) gives the data regarding the 
spread of the disease in Connecticut. 
Metcalf and Collins (1909: 46) present a map showing the distribution 
at that time in so far as it was known. By this map it was shown that 
the disease was found in Rhode Island and southern Connecticut, in 
New York, New Jersey, and Delaware, and in eastern Pennsylvania, 
Maryland, and Virginia. They add: “It can be quite confidently 
stated that the bark disease does not yet occur south of Virginia and at 
only a few points in that State.’” Metcalf (1910) states: ‘ At the present 
time it has spread from Saratoga county, New York, and Suffolk county, 
Massachusetts, on the north and east, to Bedford county, Virginia, on 
the south, and Greenbriar and Preston counties, West Virginia, and 
Westmoreland county, Pennsylvania, on the west.” 
Metcalf and Collins (1912) publish a detailed map which shows the 
results of more nearly accurate surveys of the territory along the border 
line of the spread of the disease. No new States were added to the dis- 
tribution as already given above, although spot infections were found in 
many places in Massachusetts, western Pennsylvania, Maryland, and 
northern Virginia,
