PROGRESS OF BOTANY IN SCOTLAND 227 



Among such lines of study may be named as very 

 desirable : 



1. Critical examination of the flora, and its correlation with 



Continental floras, of course subdivided into vascular 

 plants, mosses, etc. 



2. Topographical distribution as commenced by Mr. Watson, 



including the distribution by height and by habitats, as 

 well as by horizontal areas. 



3. Correlation of the distribution in his artificial areas with 



the natural divisions. Graphic or other clear and dis- 

 tinct methods for representing the distribution in a 

 manner easily prepared and easily understood should 

 be wrought out. 



4. Natural associations of plants. 



5. Relations of plants to soils, exposure, and other physical 



conditions. 



6. Relations of plants to animals, as benefited (pollination, 



seed-dispersal, etc.), or injured by them. 



7. Diseases of plants and abnormal growths, including galls, 



and their causes. 



8. Folk-lore and popular uses, rapidly disappearing in all 



parts of the country. 



9. Nature-knowledge in education, including the preparation 



of accurate lists of the plants, animals, and other 

 natural products of definite small areas, clearly under- 

 stood by teachers (e.g., parishes), and also by habitats 

 within those areas, and the formation of small school 

 gardens and museums. 



There are few with any taste for outdoor life who would 

 not find interest and benefit in one or more of these or other 

 lines of biological work, and who could not add to what is 

 yet known of the flora and fauna of Scotland. In almost 

 every line we lag behind what has been accomplished in 

 other countries. May we not hope that this will not be 

 allowed to continue ?
