22 BIOLOGICAL SURVEY OF 



The late Prof. H. C. Fernald and liis son, Dr. H. T. Fernald, 

 collected many insects on the Island, which are now in the 

 collection of the Massachusetts Agricnltural College, Amherst, 

 Mass., w^iile the summers of 1909 to 1911 were spent by the 

 late Dr. Charles Sedgwick i\Iinot at Northeast Harbor, who 

 collected at lights, specializing in Lepidoptera. These are 

 in the collection of the New England (Boston) Society of 

 Natural History. 



In connection with their work on the New England fauna, 

 the New England Society of Natural History, in 1918, selected 

 the Island of Mt. Desert as a place for part of its summer 

 work, this location presenting favorable conditions for a 

 study of insects in relation to life zones, and Mr. Charles W. 

 Johnson, Curator, spent from 10 days to 2 weeks on the Island 

 eacli summer until 1926. We met and joined forces, which 

 resulted in the publication of Part I of the Survey in 1927. 

 Our intention w^as to continue the work together as soon as I 

 was through with the first part of the marine work.^ His 

 passing put an end to that happy association, but left me 

 with the remembrance of one of the best informed and most 

 attractive of naturalists. As a mark of affection I dedicate 

 this book to his memory. 



LA BOB A TORY 



The main laboratory of the Survey is situated at Corfiekl 

 on Frenchman's Bay. There, and at Penikese, 5 miles to the 

 westward, light and other traps have been run for several 

 years, from the beginning of May until the end of October. 

 These are not the small traps, but rooms painted white, with 

 glass louvres in the windows, and lights both outside and 

 inside. These lights were changed both as to color and 

 intensity and thus a great number of individuals were taken 

 Avhich, sorted out, yielded many species. Bait traps of differ- 

 ent kinds were run constantly at both of these stations as well 

 as at other parts of the Island.
