cases of "tree-claim insects." Iowa exhibited twelve cases and Louis- 
iana three of different orders, chiefly adults. The exhibit of the Col- 
orado station consisted of eight cases of biologic material and showed 
evidence of original observations, but which while excellent in its way 
was somewhat out of place as showing the work of an experiment sta- 
tion. Oregon exhibited two cases labeled "some Oregon pests" and a 
third of "a few Oregon insects," the latter chiefly Coleoptera. 
In addition to these there were four cases of silk-worm moths, both 
foreign and native, together with blown larvae, but with no indication 
of the contributor or the source from which they were derived. 
It is to be regretted that several of the last- mentioned contributions 
were inappropriate in this exhibit and were insufficiently labeled, there 
being nothing in some cases to indicate the station making the contri- 
bution except the minute locality labels attached to the pinned speci- 
mens. It is also a matter of regret that the contents of several cases 
were completely ruined in transportation. 
A part of the Experiment Station exhibit consisted of a series of 
frames, labeled "original illustrations," contributed by different States, 
in the main original, but composed in part of illustrations from other 
sources than the station exhibiting them. There was also an exhibit 
of collecting and mounting apparatus, a series of models showing the 
internal anatomy of insects, and a small exhibit of insecticides and 
insecticide machinery, including eleven jars of kerosene emulsion pre- 
pared according to different formulae, the latter contribution from Mr. 
H. E. Weed, of the Mississippi station. 
A large exhibit, composed principally of named Coleoptera and Lepi- 
doptera, but with a fair representation from other orders, was shown in 
the Minnesota section of the Agricultural Building. It consisted of 
forty-eight large cases including, besides the above, a series of the vari- 
ous species of grasshoppers collected by the use of a " hopper-dozer," 
nine cases of economic species in their different stages, and two cases 
of galls. The installation of this exhibit was most unfortunate, the 
entire upper half of three cases having been placed so high as to ren- 
der it impossible for the average visitor to read the labeling. 
In the Canadian section was exhibited a very good series of the Lep- 
idoptera of the Dominion, each species being represented usually by 
but one or two specimens, and smaller series of Coleoptera and Hym- 
enoptera. 
In the Austrian section of this building, and in the gallery of the 
Manufactures and Liberal Arts Building, there were small series of 
jars of alcoholic material, very neatly arranged, with printed labels, 
and showing the transformations of one or more large and conspicuous 
species of the different orders of insects. 
Smaller entomological exhibits were displayed in this building by 
Java, British Guiana, and Japan. 
In the Forestry Building a few interesting collections were displayed. 
One of the best of these was that of the experiment station of West
