in certain cases, that such maps should

how to read nature. For that reason, 
in schools, associations, and clubs the 
care of natural monuments should be 
specially taught and discussed. Again, 
the inventories of natural monuments 
of distinct districts should be pub- 
lished. The maps, for instance, the 
forest-maps with natural monuments 
marked upon them, ought to be 
printed and distributed to the forest 
officials, in order that they may always 
keep the rarities in mind. In a similar 
way, geological, zoological, and other 
inventories should be published.
