4. Make a local map of the region about your school on a 

 large scale. Show all ponds, streams, lakes, marshes, mead- 

 ows, uplands, forests, etc. Show by suitable symbols where 

 various species of animals are to be found with reasonable 

 certainty. Keep in a note-book belonging to the laboratory 

 a memorandum of each new species found, and of a new local- 

 ity for a known species. In time the map and the note-book 

 will be a good account of the local distribution of species.
