with gauze. The larva? of this insect hatch from eggs placed on the vine 
just below the surface of the ground, and burrow into the roots, destroy¬ 
ing the vine. The only remedy is to keep away the mature beetles. 
The Squash Bug punctures the vine near the ground and sucks out the 
sap. Usually found in pairs. Hand picking and trapping under chips the 
best remedies. Young do no serious damage. 
The Cucumber Flea-beetle not known to do serious injury in the West. 
The Pickle Worm was destructive in 1869 in many localities. It was 
little known before, and has been scarcely heard of since. 
Essay upon the Connection between Scientific and Practical Entomology. (Trans. 
Ill. State Hort. Soc., 1871, pp. 108-112.) 
The scientific and practical are rarely united in any great degree in the 
same individual. Presumes the two qualities to be brought into exercise 
to a reasonable extent in a state entomologist. It is the duty of the 
State Entomologist to give to insects of economic interest, correct" and ap¬ 
propriate names: to determine the times and seasons when noxious insects are 
most exposed to the operations of destructive applications, or when their 
multiplication can be most effectively prevented: to bring to the investiga¬ 
tion of this subject those habits of patient study and close and rigid scrutiny 
which it is the nature of his pursuits to foster" and confirm; and to put on 
record every important fact and observation relating to noxious insects. 
It is only by the cooperation of those most interested in this subject that 
the benefits of this office may be secured. 
Lecture on Insects. (Fourth Ann. Rep. Bd. of Trustees Ill. Industrial Univ. 
for 1870-71, pp. 163-180.) 
A general article. The chinch bug discussed at considerable length.

Official Statement of the State Entomologist. (Prairie Farmer,-1872. v. 43, 
p.-.) 
Report of work done since appointment. Eleven large drawers of in¬ 
sects transmitted to the Illinois University, which are said to be in almost 
laily use. Literary work in the lines of almost daily correspondence on 
nsects with people of this and adjoining states, contributions for the 
)ress, and lectures before agricultural and horticultural societies and under 
he auspices of the State University. The preparation of a convenient 
ext-book for beginners also under way, to be published in installments 
vith his annual report; not intended to interfere with private enterprise, 
>ut expected to increase the demand for such books. No other branch of 
latural history can compare with this in importance. Appropriations dis¬ 
cussed.

deport on Entomology. (Trans. Ill. State Hort. Soc., 1872, N. Ser., v. 6, 
pp. 151-159.) 
Educational methods heretofore have been too abstract. The plan now 
1 gitated is to fix attention upon things present, tangible, and practical, 
t has been proposed to introduce natural history in place of some of 
he discarded matter. Education classified as essential, special, and gen- 
ral. Of essential education there is extremely little. The field of gen- 
i ral education is wide and diversified. Extremes to be avoided in select- 
pg from the latter. Utility of natural history discussed. From a prac- 
ical point of view, insects seem the only animals there is much use in 
tudying. The study of nature is especially suitable to furnish occupa- 
ion and entertainment during youth and old age. Teaching of ento- 
lology and use of text-books discussed. Books on the subject. Deficiency 
f suitable text-books.
