ment for first-class work in all departments of technical and economic 



entomology, sufficient for the xise of a chief entomologist, and two 

 assistants, including- furniture, a section of the Laboratory library, a part 

 of the library catalogue, record books with examples of the records, speci- 

 mens prepared and arranged in the various ways useful for reference, 

 apparatus for collecting and experiment, microscopes, a drawing equip- 

 ment, and the like, making of the whole a model establishment, which, 

 it was believed, might be profitably studied by any economic entomolo- 

 gist, foreign or American. In the insectary wgis 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 included a 

 collection of sixteen hundred species of common Illinois 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 tbe 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 butterflies 

 arranged with a view of illustrating the geographical distribution of in- 

 sect species in Illinois: a set of Illinois insects illustrating tlie work of 

 the Laboratory in supplying entomological material to the high schools 

 of the State. 



The ornithological exhibit was made in tour series: (1) a collection of 

 the game birds of the State, mounted as dead game: i2) a series of biolog- 

 ical groups mounted in various naturalistic attitudes, witli natural ac- 

 cessories indicating habits, haunts and the like; (3) a general collection of 

 all the birds of the State, grouped according to their distribution within' 

 the State at different seasons of the year: and (4) a set of the eggs of 

 birds breeding in Illinois. 



Our ichthyology was illustrated by one hundred and fifteen species of 

 the fish from various parts of the State, collected by the Laboratory 

 force and exhibited in alcohol. 



To this general account the following detailed statement may be added:
