A further effort to interest and instruct the youth oi: the com- 

 munity has led to the formation of a society known as the Andrew 

 Carnegie Naturalists' Club, which consists of between two and three 

 hundred young people who meet every other week on the afternoon of 

 Saturday in the lecture-hall of the Museum and hear lectures, often 

 illustrated by specimens and the stereopticon, and who read papers 

 upon subjects of interest. During the summer months the club 

 makes excursions in the neighborhood, and the various subdivisions 

 receive practical instruction from the staff of the Museum in the art of 

 collecting and preserving specimens of plants and animals. 



The wider diffusion of knowledge among scientific men and insti- 

 tutions is provided for by the publication of the '^Annals' and ^^lemoirs' 

 of the Museum. The former appear in octavo form, the latter in 

 quarto. This series of publications began with the first month of the 

 twentieth century, and it is hoped will not end so long as the centuries 

 run their course.
