B. MESOPHYTIC DIVISION (MESOPHYTIA) CULTURE 
SECTION. 
Consists of plants requiring the normal climatic «nd soil conditions 
of this region, useful to man and kept - his care in certain defi- 
nite artificial groups. 
II, RECLAIMED SALT MARSH FORMATION (MEADOW FORMATION, 
POIUM ). 
Consists, in adaptation to the very fine and hence poorly- 
aerated but evenly-moistened soil, of slender-rooted surface-fol- 
lowing and hence herbaceous plants, in this case grasses or 
8rass-like plants useful for forage or grain. Owing to the 
peculiar conditions here prevailing in the form of a newly-opened 
field (see page 295), no care from man directly is necessary to 
keep the plants in their desirable economic condition, for both 
Seeding and resistance to undesirable immigrants take place 
naturally as long as he preserves the field in its best condition. 
Includes, within an enclosure of dikes, the greater part of the 
area of the original salt marshes, from the sea to the head of 
tide on the rivers, and extended artificially into the lakes of the 
bogs and the bogs themselves (page 179). The formation 
includes three associations. 
4. THE PHLEUM- ~AGROPYRUM, OR TIMOTHY-COUCH ASSOCIATION, OR PHLEUMETUM. 
The characteristic, prevailing and most valued association of 
the perfectly reclaimed marsh, occurring everywhere on the 
higher parts of the marsh within the dikes where the drainage is 
good, and where the marsh soil has not been exhausted or has
