in the interior, the eye can penetrate but a few yards among the 
thickly clustered trunks. The Parula Warblers do not breed 
within these dense, dark, cedar-swamps, but may occasionally be 
found breeding on their borders. 
Between that portion of the ponds where the cedars are more 
open, and the dense cedar-swamps above, the small channels are 
so choked up with bushes, and tangled, twisted, moss-covered 
branches of the scrub-cedars, that progress in a flat-bottom boat 
(which is the safest way to travel through this region, on account 
of the uncertainty of the bogs) is very slow and laborious. 
A few remarks on the streams, and southern tributaries of 
Dennis Creek, would probably be of interest. 
The mill-dam on Sluice Creek, the southeastern branch of Dennis 
Creek, forms a lake half a mile in length, and marks the north- 
western extremity of the ‘Timber and Beaver Swamp,’ which 
stretches away nearly three miles to the east. The extensions of 
this creek south of the lake referred to, are gradually drained of 
their water by the swamps, which as I have already intimated, 
have been formed by the flatness of the land. 
These swamps are bordered with tall bushes, beyond which 
are woods of chestnut, oak, beech, laurel, and pitch-pine, inter- 
spersed with alarge quantity of holly, while the swamps themselves 
outside of the main channels, are overgrown with sassafras, maple, 
cedar, gum, magnolia, and various kinds of bushes, including 
bush-huckleberry, cranberry, alder and cedar, the whole being 
interwoven with thorny green-briars. The crooked and twisted 
branches of these trees and bushes are nearly all draped with 
beard-moss. Numerous open sphagnum and cranberry bogs are 
also scattered throughout this region. 
Among the beautiful moss-covered trees and bushes already 
described, the Parula Warblers congregate in large numbers, to 
make their summer home. They arrive from the south appar- 
ently already paired, about the first of May, and by the second 
week have commenced nest building. 
Nests can be found from the border to the middle of the mill- 
ponds and swamps, and may be looked for anywhere from under 
the tip of an outstretched or drooping branch to against the tree 
trunk, or in smaller bushes, and from one foot above the water to
