leur rareté dans la zone du M o n t - B l a n c ; on voit bien l'aire du

W i c k e n F e n is the largest existing area of the once extensive
" F e n l a n d " of E n g l a n d which occupied about 1300 sq. miles
round the W a s h . The greater part is now under cultivation or
much altered by drainage, and even W i c k e n is drained to some
extent and exhibits all the features of a drying-up marsh. The vege­
tation of W i c k e n is typical marsh ( H o c h m o o r ) with grass-like
monocotyledons — Gramineae, Cyperaceae and funcaeeae — mixed
with some dicotyledons; bog plants such as Sphagnum,
Eriophorum,
and Ericaceae are absent. A narrow reed-swamp with Phragmites
communis as the dominant plant fringes the artificial drains; where
land-formation has progressed, the general vegetation is mixed,
Cladium Mariscus, Molinia coerulea, Phragmites,. being some of the
dominant plants. The author has given special attention to the
relation of species to soil-moisture, and in a list, illustrated by a
useful diagram, he arranges the commoner marsh plants "with
respect to degree of soil moisture which would seem to be the opti-
