best on the bark of trees, others on the bare rock. In all 

 sorts of places, in summer and winter, in sunshine or un-

 Of the higher flowering plants, over a thousand species 

 have been collected within the limits of Vermont. Over 

 fifty of these are large forest trees, and about fifty more 

 are small trees or large shrubs. In such an article as this 

 each group can be treated only in the briefest manner, and 

 so can hardly be as interesting as if it could be more fully 

 described.

This portion of Vermont contains a great variety of 

 rocks which, though not of so great value commercial!}^ 

 as those found in some other sections, are of equal sci- 

 entific interest. Few, if any, of the rocks of Orleans 

 County have failed of being metamorphosed. They are 

 doubtless rocks of the Devonian and Silurian periods. 

 Most of them are non-fossiliferous in their present state, 

 but there is no reason to question, that fossils did once
