56 DACHNOWSKI: BOG VEGETATION AND PEAT SOILS 
The correlation phenomena between vegetation units in bogs 
and the character of the peat soil are not in all cases as those given 
in TABLE IV. There are many exceptions to the rule for reasons

that will be stated below. On the whole, however, the results 
may be summarized in the following well-defined relations: 
1. In color Ohio peat ranges from a greenish and grayish 
brown, due to the presence of clay and marl, through various 
shades of brown to an almost black variety. In texture peat 
varies from a loosely compacted fibrous heterogeneous meshwork of © 
plant debris to the fiberless, homogeneous variety. 
2. The physical water content of peat is higher in the coarser 
fibrous substratum of the bog meadow association. The mat, 
when adjoining open water, adjusts itself easily to changes in the 
water level of the basin. With the disintegration of the plant 
tissues the water-holding capacity of peat is higher. The concentra- 
tion of the peat solutions is very low, varying in parts per million
