animals affords for discoveries which will be of importance not 

 only to the animals but to man. 



FORESTRY DEPARTMENT. 



Under the head of construction work no reference was made 

 to planting, although this department had its most active season 

 since the beginning of the Park. 



Early in the year Mr, James L. Greenleaf was appointed Con- 

 sulting Landscape Architect, and under his supervision Mr, 

 Merkel, the chief forester, prepared and carried out an elaborate 

 system of plantations for the south and west boundaries of the 

 Park. These sides of the Park have been exposed through the 

 grading of East i82d Street and the Southern Boulevard, which 

 resulted in the destruction of the trees formerly standing on those 

 streets. 



Other plantations of shrubs and flowering plants, notably along 

 Beaver Valley Road, have been made, and nurseries containing 

 many thousands of trees and shrubs have been established. 



The total number of trees set out was 5,351, and 13,450 shrubs 

 have been planted during the year. It is the intention of your 

 Committee to devote as much money as possible hereafter from 

 our Maintenance Fund to the protection and improvement of the 

 large trees, as they are among the most valuable features of the 

 Park, which, if injured or destroyed, can never be replaced. 

 Nearly $1,500.00 was spent during the year to preserve the chest- 

 nut trees from the attack of a fungoid growth, known as cyto- 

 spora, which made its appearance during the smmer. 



Your Committee fear that the efforts of the Society will be 

 vain unless the cooperation of those controlling the adjoining 

 park area is secured, as the plague, even if entirely exterminated 

 in our grounds, can reenter from the rest of Bronx Park. 



NEW YORK AQUARIUM. 



During the year 1905, $16,632.88 was spent out of the construc- 

 tion fund provided for improvement of the Aquarium. The most 

 important work done with this money was the construction of 

 conduits under the main floor of the Aquarium to contain new 

 water and steam pipes, the original piping system having entirely 

 broken down. 



Large filters were also installed in connection with the new 

 tank for the storage of fresh sea-water. This will provide a uni-
