 Many requests for the Insect and Bird Charts first issued in 

 1910 are still reaching us, not only from points in Minnesota, but 

 from many quarters in various portions of the United States. 



INSECTARY AND EXPERIMENTAL GARDEN: The insectary and 

 garden have again proven their usefulness. Life history experi- 

 ments in connection with clover seed insects, grasshoppers, para- 

 sitic insects and various pests of farm and garden were carried on 

 during 1911 and 1912. We have a record of 100 insectary ex- 

 periments during 1911 and a hundred or more in 1912. During the 

 latter year a large amount of accumulated material was sorted and 

 recorded.
