the people civil and attentive. We retired to our double-bedded 
room to be half smothered (more Germanorum) betwixt quilt and 
feather bed, which, however snug lying in the depth of winter, 
was rather de £rop in the month of August, whilst the absence of 
mosquito curtains exposed us to the attack of those subtle 
invaders, whenever we ventured to bivouack for coolness and 
comfort outside of our downy fortress. Happily, the weather 
which had been cool all day, though fine and pleasant, rendered 
our condition supportable, and greatly thinned the forces of the

different route from that traversed on coming hither, namely, by 
Medford, &c., but a heavy rain and densely-clouded sky, seemed

and before noon assumed a drier and more favourable aspect, the.

the Pine barrens, a pretty and well-cultivated country succeeded, 
the pastures along the roads were in many places profusely 
adorned with the beautiful and fragrant Monarda punctata, now 
in full flower. It is here called Horse Mint, and from it an 
essential oil is extracted in great abundance. At a place where

species of this eminently American genus are numerous, and 
widely dispersed over the Union, being everywhere amongst the 
common plants met with. In sandy ground I gathered Tephrosia 
virginica, Digitaria humifusa, Wild Indigo (Baptisia tinctoria), 
which grows like our Broom along the borders of woods and in 
thickets very commonly ; Button Weed (Diodia teres, Spermacoce 
Diodina, Mx.), Stagger Bush (Andromeda mariana), Persimmon, 
(Diospyros virginiana), and Holly (Ile opaca). Betwixt Medford 
and Camden we saw an entire pasture field quite yellow with the 
charming Cassia Chamaecrista, called here Sensitive Pea, oF -
