W. 0. WILCOX, Dean of the College of Liberal Arts, Iowa State Univer- 

 sity: It was my good fortune to see Mr. Frank C. Pellett of Atlantic, Iowa, in his 

 Bee Demonstration before a large audience of teachers. I never witnessed a more 

 interesting illustration of the practical side of nature-study, and I have rarely seen a 

 company of teachers so thoroughly instructed and entertained by a number on an 

 institute program. 



CHARLOTTE DRYDEN, Supt. Pottawattamie County, Iowa, Schools: 

 Mr. Frank C. Pellett was instructor in nature-study in the Pottawattamie institute 

 Aug. 29 to Sept. 3, 1910. His lectures were much enjoyed by all who heard them. His 

 great interest in his work and the original way in which he presents his subjects make 

 him a most desirable instructor and lecturer.
