came from approximately the same depth in both holes (15 19 m below land
surface), it is assumed that the same layer of lignitic peat was cored at both
locations.
 Twenty samples were crushed, then boiled for 10 minutes in a 10 percent
solution of potassium hydroxide. After thorough washing, residues were mixed
with glycerine jelly, and slides prepared. At least 200 pollen grains and spores
were counted for each sample. It was not assumed that any particular pollen/
spore type would be overrepresented, though this is often the case in modern
environments. Every grain of each identifiable taxon was included in the total
pollen/spore count.
 Figures 3 and 4 display the results of the palynological analyses of core holes
 TR 1 and TR 2, respectively. Each family or genus on the graphs was present in
 at least one sample in an amount greater than one percent. In cases where taxa
 never occurred in amounts greater than one percent [e.g., Alnus (alder), Carya
 (hickory), and Liquidambar (sweet gum)], those forms were not graphed. Taxa
 which have been graphed, but which periodically were not actually counted due
 to their infrequency are indicated on the graphs by a T (trace).


 PALYNOLOGICAL COMPOSITION OF THE SAMPLES

 The palynological composition of samples from cores TR 1 and TR 2 shows
 that the vegetation of the Trail Ridge swamp was generally composed of shrubs,
 small trees, and herbs. Among the shrubs and small trees, Ilex (holly), Myrica
 (wax myrtle), Cyrilla (ti ti), Corylus (hazel), and Gordonia (loblolly bay) were
 significant. Important Herbaceous taxa included the Cyperaceae (sedges), the
 fern Osmunda, and the moss Sphagnum.
 In all cases, the palynoflora is composed of genera and families which are
 still common in the southeastern United States.
 Several other conclusions can be drawn from the graphs. If one considers
 the data for TR 1 first, the following interpretations are apparent:

 1) Taxa which are commonly abundant in great amounts (e.g., 20 percent or
 more) in modern southeastern swamp peats are not especially abundant at any
 level [note especially Quercus (oak) and Pinus (pine)].
 2) Pollen of sub-tropical genera are present, notably Cyrilla, Gordonia, and
 Magnolia (Plate 1).
 3) Pollen of shrub genera are very common, especially Myrica (28 47 percent)
 and Ilex (22 percent) (Plate 1).
 4) Some of the principal genera, including Cyrilla, Gordonia, and Taxodium
 (cypress) display distinct trends in their relative abundances. The first two
 forms decrease in abundance with depth, while Taxodium increases.
