Fig. 4. View of the southern portion of the east section of Grasse 
River bog. Sphagnum-sedge association is dominant but some dwarf heath 
shrub colonies occur. The conifer forest here occupies slightly higher non- 
peat covered ground. 
Fig. 5. <A plug of peat sod showing how firmly it is bound by the 
rhizomes and roots of the sedge. The sphagnum matrix may be seen at 
base of sedge shoots and especially in separate specimens held in left hand.
