 .■md fauna whicii nece.s.sarily follows the extension of 

 cultivated area.s. This e.xterniination may lead to the des- 

 truction of natural enemies of pests and natural sources 

 of food supply, and consideration has been given to the 

 (piestion as to whether the preservation of wild Hora 

 should not be taken into account in this connexion. 

 fJiii the gi'eatest efforts which have been directed 

 towards the presentation of wild plants and animals 

 have been prompted by educational principles rather 

 tli.in liy purely scientific ones, because the extermination 

 of wild plants removes a ii.seful source of educational 

 material and lowers the interest of a country from 

 a natural history standpniut. 



As already indicated, the spread of cidti\ation is 

 the principal factor which leads to the extermination of 

 wild oTowth, but there is also to be considered the 

 effects of manufacturing centres. Smoke and other 

 atmos]>herie impurities have a pronouncedly harmful 

 intlnence upon vegetative growth. There is also in 

 connexion with the industrial centres the effect of 

 building, drainage ami sport on natural plant associ- 

 ations, as well as professional plant collecting and 

 n.ature study operations. It will be remembered that 

 the value of vegetation in industrial centres is very 

 great because of the purifying effect which vegetable 

 growth has upon the atmosphere. It has been endeav- 

 oiti'ed in some places to regulate the.se exterminating 

 fncfors. Prussia posses.ses a well-organized State 

 l>epartment for the protection of wild plants, and in 

 England also, altlmugh the < Jovernment exercises nt* 

 control in the matter, the Selbourne Society now has 

 ;i special committee for the prevention of the destruc- 

 tion ofthe natural flora. In discussions concerning the 

 maintenance of natural plant life, the ipiestion of forest
