PRELIMINARY REPORT ON PEAT.

nee), about fifty miles away, it doubtless sometimes happens that 
the precipitation up there differs enough from that around the lake 
to set up a current through the slough in one direction or the other. 
The vegetation of this slough, as might be expected, differs a 
little from that of either river-swamps or stagnant swamps. The 
following plants were noticed in it on July 5, 1909: 
TREES 
Nyssa unifier a (tupelo gum) Acer rubrum (maple) 
Tax odium distichum (cypress) Nyssa Ogeche (tupelo gum) (to- 
Nyssa biflora (black gum) ward edge) 
SHRUBS 
Hypericum galicidesf Styrax Americana 
Rhus radicans (poison ivy) 
HERBS 
Lorinseria areolata (a fern) 
Dulichium arundinaceum 
Osmunda cinnamomea (a fern) 
Tillandsia usneoides (Spanish moss) 
Commelina hirtella 
Saururus cernuus 
Osmunda regalis (a fern) 
Hydrocotyle verticillata 
Car ex lupulina? 
Rhynchospora corniculata 
Carex Louisianica 
Boehmeria cylindrica 
Triadenum petiolatum 
MOSSES 
Sphagnum sp. Thuidium sp. 
No search was made for peat here, but it cannot amount to 
much in a swamp which is dry a large part of the time.
