Natural Features 
The beauty of the Garden reservation has suffered no 
deterioration during the year, and the protection of the 
woodlands and thickets by guard rails along paths and 
trails has permitted the wild plants to recover some areas 
which had become trampled by visitors. Hemlock and 
hickory trees have suffered from depredations of the bark- 
borers, and a considerable number of both these kinds of 
trees have died. The only practicable remedy which has 
been found is to remove the dead trees as rapidly as possible. 
No spraying or other mode of treatment has been found at 
all effective, and the damage must, apparently, proceed until 
some natural check to the development of these insects 
appears. If it were possible to induce more woodpeckers or 
other birds of similar habits to those of woodpeckers to 
remain in the woodlands, the number of borers would be 
materially reduced. However, there are far more young 
trees coming up in the woodlands than there were old ones 
destroyed. 
Additional patroling by police officers provided by the 
Police Department during the year has been advantageous 
in many ways, and it will be possible this year to somewhat 
increase the number of guards employed. 
Museums 
Additional specimens, obtained from a wide range of 
sources, have been installed throughout the museum series 
of exhibits. No modifications have been made in the general 
plan of the series of exhibits,—the collection of fossil 
plants occupying the basement of the museum building, 
the economic museum the main floor, and the system- 
atic museum the second floor. Additional cases recently 
obtained for the economic museum through a city appropri- 
ation will permit the installation of a large number of speci- 
mens held in storage. More cases are needed for specimens 
now available for installation on all three floors, and a further 
appropriation for cases has been asked.
