260 Fiftieth Report on the State Museum 



1895, It would only be necessary to extend the lines indicated in 1895 

 a few blocks westward and northward to have the two areas coincident. 

 The badly infested area in 1896 was the southern portion of the city 

 bounded on the north by State street, on the west by Dove street, and 

 on the south by Beaver Park. A limited infestation was noticed in the 

 vicinity of North Hawk street and Clinton avenue. 



The second and third broods materially extended the thickly in- 

 fested area. The westward extension is to Lark street, but in Lancaster, 

 reaching almost to Washington Park. The large second brood on the 

 Washington avenue trees, hitherto practically free from the pest, detines 

 the northwestern limit at the corner of Lark street and the avenue. The 

 defoliation of trees in Capitol Park and on the streets lying off North 

 Hawk street, indicates a northern extension of the insect which is virtually 

 limited by Third street, and easterly and westerly by North Pearl and 

 North Swan streets respectively. 



The slow spread of the insect is in accordance with the partial migra- 

 tory habit recorded by Dr. Riley, although signs of its presence in 

 limited numbers are to be found over a much larger portion of the city 

 than indicated above — practically the greater portion. 



Ravages in Albany. 



The ravages of this insect in Albany the present year were very severe. 

 Li the southern portion of the city, where the insect has been established 

 for several years, almost every English and Scotch elm was defoliated at 

 least once, and a number suffered the loss of their second leaves. The 

 early part of the season, a number of fine trees had died and were removed. 

 Apparently, it only requires three or four years of successive defoliation 

 to kill the elms. A row of nine, on South Hawk street, formerly splendid 

 specimens of the English elm, are nearly ruined and will probably die the 

 coming season. The American elms were severely injured in some places, 

 several having been nearly defoliated during the latter part of the summer. 

 The injuries to this native species are on the increase, as is evidenced by 

 the large number that have been attacked. It is safe to estimate that 

 over two hundred fine elms in'the southern residential portion of the city 

 have already been killed by this pernicious pest. From present indica- 

 tions, it is only a question of time when the European elms will be de- 

 stroyed and the American elms seriously injured, unless the insect be 

 checked in its destructive course, by effective action of the citizens of 

 Albany or its civic authorities.
