328 JOURNAL OF ECONOMIC ENTOMOLOGY [Vol. 3 



San Antonio. In his new field Mr. Dean has opportunity for serving a 

 large part of the agricultural population of Texas. Mr. Dean's new work 

 is already making a creditable showing. Considerable space in the Semi- 

 Weekly is regularly devoted to timely articles on Economic Entomology. 



The Minnesota State Entomologist, by means of an appropriation given 

 him by the last Legislature, has had prepared and distributed to all the 

 schools of Minnesota, colored charts showing some of the more common 

 injurious insects of the state, some beneficial insects, and some useful birds. 

 The chart is 36 inches by 46 inches, made to hang on the wall of the 

 school room. Under each colored figure is descriptive text, giving briefly 

 the economic relation of the insect or the bird in question to the farmer or 

 orchardist. Over seven thousand of these charts have already been dis- 

 tributed to Minnesota schools. 



The Entomological Division of the Minnesota Experiment Station is now 

 publishing a montlily leaflet, or journal, containing timely items of interest, 

 advice and suggestions to farmers, housekeepers and gardeners, mailed free 

 to any citizens of Minnesota who request it. This is not a bulletin, but 

 more like a circular. Its aim is to get timely advice and news of insect 

 conditions to the Minnesota agriculturists during the growing season, and 

 is to I>e published and issued the first day of May, June, July, August and 

 Semptember. 



The increased interest in Entomology is shown by the following statistics 

 from Prof. H. F. Wickham of the University of Iowa. Last year he had an 

 increase in his classes of about 50 per cent over the best previous record 

 and this year shows a furtlier advance of 40 per cent over last. He now has 

 close to 100 students taking work in entomology, though the courses are en- 

 tirely elective.
