found necessary during the winter of 1900-1901 to remove 

 many dead trees, although not enough to be missed ; on the 

 contrary, very few trees died during the past year, and these 

 have already mainly been removed. Picnicing in the woods 

 has continued, and has not been restricted except in cases 

 where a large number of people wished to congregate ; it 

 has therefore been necessary, during the summer and autumn 

 to detail a boy to the work of collecting paper and other rub-

 not been given, however. 



The forests may be much more certainly and easily pre- 

 served after the system of walks and drives planned have 

 been built through them ; the greater number of pedestrians 

 will naturally follow the paths, and may be directed to do so 

 when it becomes necessary. The paths and roads at present 

 under construction or already built will serve to lead to the 

 forests at several points at which their extension into and 

 through the forests may next be taken up. It will be prefer- 

 able to build the forest drives and paths by day laborers un- 

 der our immediate supervision than under contracts. 



The cleaning and watering of the driveways already built

The lawns and banks have been rolled and mowed by horse 

 and hand mowers and the surface drainage basins have been 

 inspected and cleaned out when necessary. 



The grass on the arboretum tract and other undeveloped 

 areas has been cut for hay and stacked in barracks near the 

 stable, more being harvested than needed for our horses ; a 

 second barrack, like the one described in my last annual 

 report, was built during the summer.

 2,482 volumes besides several thousand pamphlets and parts, 

 the total number of bound volumes being now 11,314. Gifts 

 of books have been numerous and very welcome ; they have
