information concerning their origin could be obtained, but it is 
believed that they were imported when 3 or 4 years old, that the 
disease came with them, and that they have been serving ever since 
as a center of infection each season for the Kibes in that vicinity. 
During the season of 1913 the disease appeared on but few Kibes 
bushes near the two trees above mentioned. The pines of the vicinity 
are to be held in quarantine and inspected each spring. In spite of the 
recent pessimistic opinion of those most directly concerned in the mat- 
ter, 1 there is every reason to believe that the disease will soon be eradi- 
cated at this point, now that the center of infection is finally located. 
The conclusion that " complete eradication of the disease is no longer 
possible'' is apparently meant to apply to the entire country and is 
based on the fact that blister rust was established at Geneva and the 
supposition that it was established in other places in Xew York, Mas- 
sachusetts, and Connecticut. Xow that the disease is well in hand in 
the Geneva area (the most dangerous one known at that time in the 
entire country 2 ) , there seems to be no sufficient reason for giving up the 
fight against as dangerous a disease as this promises to become if 
unchecked. This is especially true in view of earlier statements as 
to the seriousness of this disease. 3 
NEW OUTBREAKS. 
Early in July the writer received specimens of white pine affected 
with blister rust from a point in northern Vermont which had not 
been previously known as harboring the disease. Inquiry showed 
that it was present upon native trees in that vicinity, this being the 
first known instance in this country. A visit was immediately made 
to determine the facts in the case, and the disease was found in the 
ornamental plantings of a large private estate. The original source 
of infection is unknown. It is quite possible that a few imported 
white-pine trees were obtained years ago, although it is definitely 
known that most of the trees in the vicinity are native and grew in 
the near-by woods. At any rate, the disease has been in some of the 
trees about 10 years, judging from the location of the cankers and 
their general appearance. Of the total number of white-pine trees 
in that vicinity, about 150 in all, more than 50 were found to be 
visibly affected by the disease. How many may later develop blister 
rust is, of course, unknown, but probably 5 or 10 per cent will do so. 
Already about 33J per cent have it, which should be sufficient to con- 
vince the occasional skeptic that this will be a serious disease * if 
allowed to run its course in this country.
