156 Nature protected 
Holland 
On the invitation of the Dutch 
Botanical Association, in 1904, I read 
a paper on the protection of remark- 
able plants and animals \ In the 
following year, at Amsterdam, a con- 
ference took place for the purpose of 
discussing the steps which should be 
taken for the protection of natural 
monuments, and an Association for 
the Protection of Natural Monuments 
in Holland was instituted. 
The reservation of the Naardermeer, 
in the south of the Zuider Zee, is of the 
greatest importance, as all lakes and 
moors there are threatened by draining. 
The avifauna of the Naardermeer is 
of very great interest.
