THE HARVARD LABORATORY OF ANIMAL PSYCHOLOGY 183 



of scores of invertebrates and vertebrates should not be observed 

 under conditions of varying degrees of freedom. The country 

 is already rich in animal life. Indeed, the Pemigewassett 

 Valley, in which the station is located, is well-known to orni- 

 thologists because of the abundance of birds. It will undoubtedly 

 prove feasible, as occasion arises, to import organisms for study. 



The station is at present available during the months of June, 

 July, August and September. It is at this time that work in 

 Cambridge can least satisfactorily be conducted. The climate 

 at Franklin is healthful and agreeable. For a few days in July 

 the heat is at times oppressive, and before the end of September, 

 frosts are likely to chill the enthusiasm of the field worker and to 

 encourage his return to the city laboratory. 



Only a small group of observers can be received at the Field 

 Station during the summer. Each individual is responsible for 

 his living expenses, and for the present at least, he must be res- 

 ponsible, also, for such expenditures as the conduct of his work 

 demands. The station, as stated above, is the property of the 

 writer, and is by him, in his capacity as director of studies in 

 animal behavior at Harvard, placed at the service of a selected 

 group of investigators during the summer. 



Behavioristic work was initiated at the Franklin Field Station 

 in the summer of 1912, by a study of habit -formation in earth- 

 worms, conducted by Ada W. Yerkes and the writer. This was 

 a continuation of work begun previously in the Harvard Labora- 

 tory. 



Two investigations were pursued during the second season 

 (June to October, 1913) by Mr. C. A. Coburn and the writer. 

 Of these, the one was a study of the transmission of savageness 

 and wildness in mice, and the other, a naturalistic and experi- 

 mental investigation of the behavior of the crow. The first of 

 these was transferred for the season from the Harvard Labora- 

 tory. The second was a new inquiry which indeed could be con- 

 ducted to advantage only at the Field Station. Both of these 

 investigations prospered most encouragingly during the season, 

 and we confidently expect and hope that they may be continued 

 during the coming summer. Mr. Coburn, in a paper which 

 appears in this number of the Journal (p. 185), has given a 

 preliminary account of the results of certain of his experiments 

 with crows. The naturalistic data which we obtained are reserved
