November 16. 

I now take notice of the green polypody on the rock.

P. M. – To Nawshawtuct by boat with Sophia, up Assabet.

The river still higher than yesterday.

I paddled straight from the boat's place to the Island.

I now take notice of the green polypody on the rock and various other ferns, one the marginal (?) shield fern and one the terminal shield fern, and this other, here inserted, on the steep bank above the Hemlocks.

I admire the fine blue color of the cedar berries.

H. D. Thoreau, Journal, November 16, 1853

By boat with Sophia, up Assabet. See October 6, 1856 ("Carried Sophia and Aunt up the Assabet"); November 14, 1855 ("Up Assabet with Sophia. A clear, bright, warm afternoon.”)

The river still higher than yesterday. See November 14, 1855 ("The rain has raised the river an additional foot or more, and it is creeping over the meadows.")

I now take notice of the green polypody on the rock. See November 17, 1858 ("The polypody on the rock is much shrivelled by the late cold") See also October 23, 1857 ("The ferns which I can see on the bank, apparently all evergreens, are polypody at rock, marginal shield fern, terminal shield fern, and (I think it is) Aspidium spinulosum,. . .The above-named evergreen ferns are so much the more conspicuous on that pale-brown ground. They stand out all at once and are seen to be evergreen; their character appears.”); November 2, 1857 (“My thoughts are with the polypody a long time after my body has passed. ”); November 5, 1857 ("At this season polypody is in the air. ") and November 16, 1858 ("the lycopodium dendroideum, complanatum, and lucidulum, and the terminal shield fern are also very interesting.")

I admire the fine blue color of the cedar berries. Note Juniperus virginiana, sometimes known as red cedar, is a species of juniper. The berry-like female  seed cone  is dark purple-blue with a white wax cover giving an overall sky-blue color ~ wikipedia
