age. A label attached explained this and stated that a goodly pro- 
portion of these deaths were due to fly-borne diseases. 
In addition to this feature in our booth in 1913, house flies were 
shown alive, in maggot and pupal stages, as were also mosquitoes, 
and the tables were filled with cases showing mounted insects of 
economic importance. This booth in the Agricultural Building was* 
crowded with visitors practically all the time. 
In the Horticultural Building there was an exhibit of different 
spray pumps, nozzles, insecticides, and one power sprayer in action 
in charge of Mr. Ruggles and Mr. Peake. Appropriate signs in 
different parts of the Fair Grounds directed visitors to these two 
booths. The spraying exhibit was repeated in 1914. 
Correspondence and Lectures. In the vicinity of 2,000 letters 
were written by the Department in 1913, as well as the usual num- 
ber of postal card replies, largely in answer to inquiries regarding 
insects. In 1914 the number was somewhat greater. 
Your Entomologist delivered, during 1913, twenty-six lectures 
in different parts of the state. A large proportion of this number 
was devoted to the subject of the House Fly and presented before 
women’s clubs, schools and civic bodies. These lectures dealt with 
the habits of this insect and its control in cities and towns, and 
were illustrated by lantern slides. A few lectures were given on 
“Mimicry in Insects,” one before the State University, and at 
other times at St. Paul schools. ‘Grasshopper Control” was the 
subject of another lecture. Papers were also read in Cleveland, 
Ohio, before the American Association of Economic Entomologists 
and the American Association of Horticultural Inspectors. At the 
same place, a report was made of the work of Entomologist’s 
Employment Bureau, carried on by the American Association, of 
which Bureau the writer was director during 1912-1913. This 
Bureau is managed by the American Association and is planned 
to secure positions for entomologists and to provide institutions 
seeking entomologists with desirable men, at the mere cost of 
operating. 
In December, 1913, the Entomologist spoke at Atlanta, Ga., 
before the two National Associations above mentioned. Occasional 
lectures were given during the winter, and in June, 1914, we partic- 
ipated in “University Week,” lecturing in six Minnesota towns.
