80 THE XATURE-S7UDY REVIEW [6:3-Mar., mo 



Little in the way of results can be reported as yet. In the 

 data obtained during the first semester, a slight advantage is 

 found, after all corrections have been made, in favor of the 

 economic approach; and a summary of these data, by Mr. Gil- 

 bert, will appear in an early number of the Journal of Educa- 

 tional Psychology. But the complicated nature of the ex- 

 periment, the difficulty of controlling some of its factors, and 

 the lack of developed technique for such experimentation will 

 undoubtedly make it necessary to try the thing a number of 

 times before any dependable conclusion can be reached. 



It may be submitted, however, that such experiments, made 

 in the schoolroom itself, under the actual working conditions 

 of teaching, are of the only kind that can ultimately solve the 

 problems of method; and that many such experiments should be 

 attempted in many places and reported for what they are worth, 

 to help at least in the development of the needed technique. 



ACKNOWLEDGMENT 



The Review expresses its appreciation of the assistance 

 it has received from contributors and others in assembling the 

 material for this issue for publication at the earliest possible 

 date. It acknowledges indebtedness to H. W. Fay, of DeKalb, 

 111., for the loan of certain plates, and to the Florida Audubon 

 Society for the loan of plates for four of the illustrations in the 

 article by Prof. C. F. Hodge. These, four plates were used in 

 the beautiful leaflet on the Bobwhite, issued by the Florida 

 Audubon Society. This leaflet (contributed by C. F. Hodge) 

 may be obtained by non-residents of Florida, at $1.50 per 100, 

 from Mrs. L. P. Bronson, Treasurer, Florida Audu1)on Society, 

 Maitland, Florida. 



The Illinois State Academy of Science at its recent an 

 nual meeting, provided for a committee of three "to cooperate 

 with existing agencies for the advancement of nature-study in 

 elementary schools." It will be recalled that the California and 

 the New Jersey academies have taken somewhat similar steps 

 indicative of the general interest in nature-study throughout the 

 coimtry.
