Monday.
To Middleborough ponds. There was no boat on Little Quitticus; so we could not explore it.
Set out to walk round it, but, the water being high,— higher than anciently even, on account of dams, — we had to go round a swamp at the south end, about Joe’s Rocks, and R. gave it up.
I went to Long Pond and waited for him.
Saw a strange turtle, much like a small snapping turtle or very large Sternothaerus odoratus, crawling slowly along the bottom next the shore. Poked it ashore with a stick. It had a peculiarly square snout, two hinges to the sternum and both parts movable. Was very sluggish; would not snap nor bite. Looked old, being mossy above on the edge, and the scales greenish and eaten beneath. The flesh slate colored.*
I saw that it was new and wished to bring it away, but had no paper to wrap it in. So I peeled a white birch, getting a piece of bark about ten inches long. I noticed that the birch sap was flowing. This bark at once curled back so as to present its yellow side out ward. I rolled it about the turtle and folded the ends back and tied it round with a strip of birch bark, making a very nice and airy box for the creature, which would not be injured by moisture, far better than any paper, and so I brought it home to Concord at last.
As my coat hung in R.’s shanty, over a barrel of paper, the morning that I came away the turtle made a little noise, scratching the birch bark in my pocket. R. observed,
“ There is a mouse in that barrel. What would you do about it?”
“Oh, let him alone,” said I, “ he ’ll get out directly.”
“ They often get among my papers,” he added.
“ I guess I ’d better set the barrel outdoors.”
I did not explain, and perhaps he experimented on the barrel after my departure.
As I sat on the shore there, waiting for R., I saw many mosquitoes flying low over the water close to the sandy shore.
The turtle when I first saw him was slowly and tremblingly pacing along the bottom, rather toward the shore, with its large head far out on its outstretched neck. From its size and general color and aspect, I did not doubt at first that it was a snapping turtle, notwithstanding the season.
H D. Thoreau, Journal, April 13, 1857
To Middleborough ponds. See June 30, 1856 ("To Middleborough ponds in the new town of Lakeville") and June 24, 1856 ("To Sassacowen Pond and to Long Pond")
I rolled [the strip of birch bark]about the turtle and folded the ends back and tied it round with a strip of birch bark, making a very nice and airy box for the creature. . .and so I brought it home to Concord at last. See April 25, 1857 ("I find that I can very easily make a convenient box of the birch bark, at this season at least, when the sap is running") See also April 23, 1856 ("Brought it [a beetle] home in a clam’s shells tied up, —a good insect-box."); June 23, 1852 ("I am inclined to think that my hat, whose lining is gathered in midway so as to make a shelf, is about as good a botany-box as I could have and far more convenient. . .").
* The Freetown Turtle compared with Storer’s Sternothoerus.
Answers to the generic description, except perhaps that the posterior valve of the sternum is movable.
Compared with the S. odoratus.
There is no peculiar scent to it. The upper shell is flattened on the dorsal ridge for the width of the dorsal plates and is not carinated there. (I find one as flat, and others are not carinated.) Color out of water a dirty brown. The marginal plates are a little narrower.
The sternum (as well as that of my S. odomtus) is apparently composed of 11 instead of 9 plates, the anterior portion being composed of 5 instead of 3 plates. The posterior portion is distinctly movable, much more than the odoratus, and it is quite rounded on the sides.
Irides not distinct. It appears as if blind. No yellow lines what ever on the head or neck. Jaws not dark-brown, but bluish-slate, as is the skin generally.
My two S. odoratus are 3 3/5 inches long by 2 1/2 wide and 1 1/2 inches high, being highest behind. The Freetown turtle is 4 inches long by 2 3/4 and 1 5/8 high, being highest forward. It has much green moss (?) on the rear and marginal plates, and the scales of the sternum are greenish and worn or carious. It is quite sluggish. Otherwise it apparently answers to Storer’s S. odoratus.
