making treatise upon the whole subject of the protection of nature 
and natural monuments. A Prussian state bureau was then founded 
in Danzig in 1906, and transferred to Berlin in 1910. A few examples 
of individual plant dangers and protection are now in order. 
Eryngitim maritimuni (Sea Holly), a plant growing along the 
coasts of the Baltic, has been torn out in such cjuantities for floristic 
uses as to be seriously endangered. Attention having been called to 
this fact, it has been placed upon the list of plants that should be 
protected and the plucking forbidden. 
Betula nana (Dwarf Birch), a species that is common in Scan- 
dinavia, Finland and Russia, is found in only a very few places in 
Germany and is much endangered by the cultivation of the moors 
in which it grows. This plant is now protected everywhere, partly 
by the reservation of the places where it grows, e. g., in Xeulinum, 
near the Drewenzerwald, and partly by protection of individual 
plants or groups. 
Cypripediiim calccolus (Venus Slipper), a beautiful orchid. 
Trapa natans, a curious water plant, and others. 
Ilex aqiiifoUuui (Holly), Taxus baccata (Yew), Viscuui album 
(Mistletoe), are also protected in localities where they are rare or in 
danger of extermination, e. g., the yew in the Fies Busch, of 45.7 
acres. 
An interesting plant association is a salt marsh near Artern, 
Saxony, which was threatened by cultivation but has been preserved 
together with the typical growths of Ruppia rostellata. Cladium 
Mariscus, Glaux maritima, and others. 
In Brandenburg, near the ruins of the Abbe)' of Chorin, the 
Plagefenn and See have been reserved as an absolute sanctuary 
by the State Forest Administration. This district comprises 417 
acres, and consists of forest, moor and lake, constituting a typical 
Brandenburg landscape, with characteristic plant associations and 
formations, which has remained untouched by the hand of man. 
since its inauguration in 1907. 
A large tract of three to four German square miles, in the Liine- 
burger Heide, has been acquired by the Stuttgart " Verein Natur- 
schutzpark." This district includes the ^Mlseder Berg, the highest 
elevation in the Northwest German plain, and represents a well- 
preserved and typical moor and heather country. 
In the administrative district of Cassel, at Sababurg. the Reinhards- 
wald of about 133 acres of forest, consisting of particularly fine old 
beeches and oaks, some of the latter having a circumference of
