that of the University College of Science, and opposite the + 
exhibits of the College of Agriculture and of the Agricultural 
Experiment Station, with only an aisle intervening. 
The leading features of our display were a most excellent 
collection of the birds of the State and of their eggs; a series of 
entomological collections, scientific, educational and economic; 
a model economic entomologist’s office and insectary; and a 
nearly complete display of the fishes of Illinois in alcohol. 
The entomological collections were shown in connection with 
the model entomologist’s office, which contained five hundred 
and forty square feet in one room, with an annex twenty feet 
long by eleven feet wide for an insectary. Into this room were 
put a select and carefully arranged equipment for first-class work 
in all departments of technical and economic entomology, suffi- 
cient for the use of a chief entomologist and two assistants, 1n- 
cluding furniture, a section of the Laboratory library, a part of 
the library catalogue, record books with examples of the records, 
specimens prepared and arranged in the various ways useful for 
reference, apparatus for collecting and experiment, microscopes, 
a drawing equipment, and the like, making of the whole a 
model establishment which, it was believed, might be profitably 
studied by any economic entomologist, foreign or American. In 
the insectary was placed apparatus of various kinds for the 
breeding and rearing of insects of injurious habit, and for the 
cultivation of the plants subject to insect injuries upon which 
experimental methods might be demonstrated. 
The special exhibits made in this entomological department 
‘ncluded a collection of sixteen hundred species of common IlIli- 
nois insects, so selected as to present a correct general idea of 
the insect life of the State; separate collections of insects, in their 
various stages, injurious to corn, to wheat, to the apple, and to 
the strawberry in Illinois, together with characteristic examples 
of their injuries; a special exhibit of the food of one robin for one 
year, based upon studies made at the Laboratory and published 
in our Laboratory bulletins; a set of insects ascertained to have 
been eaten by birds; a similar series eaten by fishes; a set of but- 
terflies arranged with a view to illustrating the geographical dis- 
tribution of insect species in Illinois; and a set of Illinois insects 
| ustrating the work of the Laboratory in supplying entomolog- 
ical material to the high schools of the State.
