shortages of men have caused serious deterioration in certain 

 hnes, and special efforts must be made in 1919 to cal:ch up with 

 these repairs in order to prevent disastrous results. This is true 

 chiefly in walk repair work, in forestry and in repairs on old 

 buildings and installations. 



It is imperative that important work should be done in the 

 section of the Park east of the Boston Road ; between the Boston 

 Road and the river. The main walk should be built to Bronx- 

 dale, and some of the steeper slopes protected from the public, 

 as the bare, hard, tramped soil of these slopes is beginning to 

 erode badly, and many of the fine old trees are dead or dying. 



The plot east of the Bronx River adjacent to 180th Street 

 should be cleaned, graded and seeded. 



Suitable guard rails should be supplied along the east river 

 walk, and the entire walk, nearly a mile in length, should be 

 resurfaced. 



The entire forest east of the Bronx River, in which no re- 

 pair or pruning work has been done in six years, needs a great 

 deal of attention, and I hope that funds for this purpose will 

 be available.

Pliotograpliii. — During 1918 the photographic work included 

 views of various subjects in the Park, musk ox, chimpanzees,

 ing pigeons, beavers, beaver works, sloth bears, stump-tailed 

 lizards, etc. ; bear dens, details of construction work, forestry 

 work and a series of negatives at the Aquarium. 



The continued scarcity of glass as a support for sensitive 

 emulsions is bringing about an important change in photographic 

 work, and that is the substitution of cut films for dry plates. 

 As most of the glass used in this work was produced abroad, the 

 supplies from those sources were practically eliminated. This 

 necessitated the finding of a substitute for glass, which has been 

 realized by the use of heavy celluloid. These films are now 

 being produced and are rapidly taking the place of the old glass 

 plate, an event that is as of much importance as the introduc-
