 number may be expected later in that month. The postoffice technicalities 

 which delayed mailing the February and March numbers are now satis- 

 factorily arranged. Beginning with the September number, our printer will 

 issue The Review in the first week of each month.

 pages in each issue. 



(3V Please remember that The Review is not a journal for beginners 

 in nature-study ; but it aims to be for nature-study what Science and similar 

 journals are for science, namely, a journal for the publication of the latest 

 ideas of the best workers. If you have worked out soma new point in theory, 

 method, or subject-matter of nature-study, it belongs in The Review. Let 

 us have your best ideas for publication. It appears from examination of the 

 mailing lists that The Review now goes to all American educators and scientific 

 men who are commonly known to he seriously interested in nature-study. 

 Therefore, in no other journal will your ideas concerning nature-study reach 

 directly so many people whose opinion you value. By contributing to The 

 Review you will best help the gn at movement for which it stands.
