Insectary and Experimental Garden. Mr. William Moore, As- 
sistant Professor of Entomology, was added to our staff in October, 
1913, and has charge of insectary methods and experiments. He 
appears to be placing this feature of our work upon an excellent 
footing. We have been granted by the Director of the Station a 
plot of ground consisting of about 2% acres and including some 
orchard land for experimentation. Some of this was sown in clover 
for work with clover insects, and a part plowed and utilized by 
planting thereon a few truck crops for experimental work. 
Mr. Moore reports 127 general experiments carried on during 
the year, and 75 others of a special nature in charge of the heads 
of different sections. 
Insect Collections. Considerable additions have been made to 
our collections in Hymenoptera, popularly referred to as the group 
containing the Bees, Ants, and Wasps. This has been done, pri- 
marily, for the proposed work upon this order of Minnesota in- 
sects, a project approved by the Director of this Station. 
Exhibits. Reference has already been made to the House Fly 
Exhibit at the State Fair in 1913. In this exhibit a large and very 
accurate model of the House Fly was shown (see plate), 4 feet 
long, with filth attached to feet, wings and hairs of the body. There 
was also a model of a farm house and outbuildings, with flies going 
from the latter, and from a manure pile, into the windows of din- 
ing room and sick chamber. Over the fly exhibit was suspended 
a red electric light globe which flashed every 40 seconds, that 
being the rapidity at which (according to a recent census report) 
a child died somewhere in the United States under five years of
