  Visited the Tyler Bog this morning and spent nearly
two hours there. It is as interesting as ever and indeed
but slightly if at all changed since I first saw it in 1871.
The spruces and larches scattered over it do not seem to
have increased, either in number or stature, although nearly
all are still living and I do not think that any have 
been cut of late. Even the old corduroy road that crosses it is
just as I remember it in the earlier days and I am
told that only a few fresh of its [?] logs have [ever been replaced.] added to it.
There is one disfigurement that I regretted to see viz. a line
of telephone poles and wires leading to Dutton's place on
Metalluc Sound and installed last summer. Where the road
crosses it the bog is crossed by the road is about 150 yards in width. How far
it extends in the other two directions (north and south) I
could not see and do not accurately know but I believe its
length is something over a mile. It is a wild and solitary
place very like the bogs in Artic [Arctic] America known as "Muskegs"., 
I have no doubt, judging by what I have read of the latter.
 Perfectly level and surrounded on every hand by hills and
ridges it is wet or very moist at all seasons yet never
flooded I believe. Throughout, its entire extent or, at least. as
far as I have ever explored it, it is carpeted deep with
Sphagnum moss varying in color from olive green to a fine
coppery brown. There are few places where this moss is not
more or less concealed by low-growing shrubs of which Ledum,
Cassandra, a dwarf willow, Alnus viridis & Viburnum
appear to be the most abundant. Kalmia glauca, Andromeda
polyfolia [polifolia], Rhodora, Pyrus arbutifolia, Spiriae salicifolia,
and a small honeysuckle (C. cartelera) are less
numerously represented, yet rather common & indispersed.
Of these the Kalmia, Andromeda, Rhodora & Honeysuckle were
