Lectures: The following lectures tipon insects and kindred 

 subjects, illustrated in most instances with stereopticon, were given 

 in the months and at the places named : April, 1907, Lake City ; De- 

 cember, 1907, Pelican Rapids ; January, 1908, Hope Chapel, Minneap- 

 olis; February, 1908, Twin Valley; July, 1908, Spicer (Chautauqua

Correspondence: The Entomologist's mail has l^een increas- 

 ing each year. Its character is, to a certain extent, indicated by the 

 insects listed under "(^ieneral Insect Conditions," for there were nu- 

 merous inquiries in connection with these. In 1907 there were ap- 

 proximately 1,500 letters, and in 1908, 1.767 letters. The bulk of this 

 correspondence occurred between June 1st and September 15th of each 

 year, the period when insects are most active, and consequently when 

 the heaviest demands are made upon the Entomologist. 



Nursery Inspection: In 1907 fifty-four nttrseries were ins])cct- 

 ed, and certificates granted their owners. In 1908 this number was 

 increased to fifty-nine. As a rule we find Minnesota nurseries well 

 cared for and free from serious pests. A careful watch, however, will 

 be kept for Crown Gall. 



Insectary : The inscctary is proving especially valua])le in our 

 work. We have reared several parasites, some of them new to science, 

 and from various pests, notably the Cabbage Maggot, and have also 

 been enabled to make careful study of life histories of grain insects 

 and other injurious pests, and to so work upon these in the dead of 

 winter as to really double the ciuantity of work which was done before 

 the building was erected. In 1907 four hundred and sixty separate 

 experiments were carried on m the insectary, and in 1908 to date, four 

 hundred and fourteen. Experiments now running embrace such sub-
