widespread defoliation. The beetles appeared to winter in excellent 
condition and one would expect similar general injury the following 
year. There was severe damage in 1912 in most localities where 
the beetle was very injurious the preceding year, but it was much 
more restricted and was not readily explainable by any local condi- 
tions. Some trees had the foliage practically skeletonized while 
others, though unsprayed, were but slightly damaged. A portion 
of this sporadic injury is doubtless explained by spraying or the 
lack of it, though even this factor does not account satisfactorily 
for all cases. The relative vigor of the trees also had an influence 
as pointed out above. 
The elms of Catskill were very badly affected, especially just 
west of the main business street and particularly in the vicinity of 
the court house on Broad street and at the corner of Williams and 
Spring streets. Some of the trees were nearly bare July toth, 
others had over half the foliage, while the remainder of the leaves 
were brown and nearly lifeless. Here and there elms could be 
seen which were in a fairly good condition. Some of these, we 
were informed, had been sprayed. There was comparatively little 
injury at a distance from the business center. The above was one 
of the most striking instances of damage observed the past season. 
At Mount Vernon a number of trees had brown, dead foliage, and 
the same was true of other communities in that general section, 
such for example as Tarrytown, Port Chester and New Rochelle. 
There was more or less injury here and there in cities and vil- 
lages along the Hudson valley. There was rather severe injury 
in the village of Kinderhook, due to no spraying, and the same was 
true, though to a less extent, of the trees on the side streets of 
Lansingburg. There was mostly very severe injury to the elms at 
Valley Falls and some scattering damage to roadside and field trees. 
The general condition of the elms at Hoosick Falls showed a 
marked improvement over that of last year, due largely to spraying. 
Elms which had been thus treated, whether on the street or on 
private grounds, were mostly in excellent condition, while the un- 
sprayed trees on back streets, in back yards and especially in the 
section across the river from the main portion of the town, ex- 
hibited a marked contrast. The elms of Albany are in a much 
better condition than the preceding year, due to more thorough 
work in spraying. One of the perplexing elements of the situation 
is that many of the elms in Watervliet, though unsprayed, exhibit 
comparatively little injury. The trees of Mechanicville hardly show
