THE FOREST SCHOOL AT EBERSWALDE. 241 
large collection of specimens of bark and wood injured by various 
animals and insects. These consist both of small specimens under 
cases and also of larger blocks arranged round the walls, showing 
the characteristic way in which the insect works. Specimens 
illustrating the work of woodpeckers and other kindred species are 
also shown, and also the dust left in the galleries of wood-boring 
beetles, etc. The insects themselves, together with many others of 
less importance, are arranged in cases fixed on a revolving stand. 
The other part of this collection consists chiefly of forest mammals 
and skeletons of the same, and also a collection of horns of 
different species of deer. It is rather interesting to note in 
connection with this collection, the great number of specimens of 
seedlings and young trees injured by the various members of the 
mouse family, and by the extent of the injuries inflicted one might 
easily mistake them for the work of a larger animal. As in 
connection with the insect pest, so here also are shown the remains 
of seeds and fruits after their edible portions have been devoured 
by the animals. Specimens of hoofs and paws of the larger 
animals are exhibited in order that their remains may be recognised 
if met with in the forest, great importance being attached to 
everything in connection with the chase. 
In the chemical and physical museum are shown the majority 
of the various organic and inorganic elements commonly met with, 
and also a small collection of metals. The physical portion consists 
of instruments used in various scientific observations in connection 
with meteorology, chemistry, electricity, and microscopy, besides 
various inventions for the purpose of demonstrating the laws of 
physics and mechanics. 
The collections in connection with mineralogy and geodesy con- 
tain specimens and instruments relating to those sciences, and do 
not require detailing. 
In the drawing-class room are several very interesting maps of 
forest districts, and also models in plaster of the principal mountain 
ranges in Germany, showing the arrangement of the forest com- 
partments. 
The library, which is placed in a portion of the old buildings, 
contains between five and six thousand works on all subjects con- 
nected with forest science, and also on the allied branches of 
agriculture and gardening. According to the catalogue of 1885, 
the following number of books on the various branches were 
present :—250 on forest and chase history; 134 text-books on forest
