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 19th, 

 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
