movements. The ringdoves will assemble in count- 

 less multitudes, the finches will unite in vast as- 

 semblies, and waterfowl will flock in thousands to 

 the protected lake, during the dreary months of 

 winter : but, when the returning sun spreads joy and 

 consolation over the face of nature, their congregated 

 numbers are dissolved, and the individuals retire in 

 pairs to propagate their respective species. The

About two miles to the eastward of this place are
