 satisfactory. There were several sets of bark with cross sections 

 and lengthwise sections of the wood all carefully labeled. There 

 were also many large collections of twigs accurately determined; 

 there were 63 species shown on one card. And best of all, there

were collections of mounted specimens showing wood in cross 

 and lengthwise sections, the bark, the leaves, and the fruit. There 

 were several complete collections of our native evergreens and 

 one particularly excellent of our native oaks. There were also 

 numerous collections of autumn leaves, with colors well preserved, 

 each leaf being specifically labeled. One cross section of a tree 

 was correlated with history. A pin to which a paper was attached 

 giving an important historical occurrence was set in the ring of 

 growth of the year in which it happened. This covered about 

 fifty years of history and it attracted much attention. 



The plant collections were numerous. One was especially well 

 mounted, containing 63 specimens of common field plants. There 

 was also a collection of mosses, lichens and ferns.
