Total 1742 



The total number of specimens which have been added to the 

 state herbarium from all sources is 2542, of which 1742 were received 

 either in exchange or as contributions, as indicated above. The 

 other 800 specimens were collected by the State Botanist in the 

 following counties : 



In addition to the 1070 specimens reserved from the current col-

 collected to be used in exchange with other institutions.

 persons. This is a marked increase over the plant identification 

 service rendered during the preceding year (1920), when 260 

 specimens were identified for 140 different persons. 



Chestnut blight (Endothia parasitica). During 1921 

 observations were made at various localities on the spread and extent 

 of the chestnut blight. Northward the disease has spread to the 

 northern limits of the distribution of the host in Rensselaer, Albany 

 and Saratoga counties, although owing to the scattered distribution 

 of the chestnut northward, not all the trees are as yet infected. In 

 the lower Mohawk valley, owing to the scattered distribution of the 

 host tree, the disease is as yet somewhat sporadic. While there is 

 a rather thin and uneven natural distribution of the chestnut up 

 the Mohawk valley and on over into the Ontario lowlands where it
