of October last, I mentioned the plants seen on a short visit to 
one of the smaller isles, and now I will speak of one still smaller. 
Between Little Cranberry Island and Baker's Island, is a ledge of 
rocks about a mile in length, bare only at very low tides. About 
midway of it is a low, treeless islet, which is above the level of 
high tide. It is protected by a bank of shingle thrown up by the 
waves, while its interior is covered with verdure. The area is 
hardly more than an acre. It is seldom visited, but I had an 
opportunity on September 2d of spending a few minutes upon it, 
and noted the following plants : 
Cakile Americana, Nutt.; Geranium Robertianum, L.; Lathy- 
rus maritimus, L.; Potentilla Anserina, L.; Rubus strigosus, 
L.; Ribes hirtellum, Mx.; CGnothera biennis, L.; Archangelica 
Gmelini, L.; Ligusticum Scoticum, L., in great abundance; 
Aster (?) tardiflorus, L.; Solidago sempervirens, L. ; Ambrosia 
artemisiefolia, L.; Achillea ‘Millefolium, L.; Cnicus arvensis, 
Hoffm.; Mertensia maritima, Don., in great profusion; Convol- 
vulus sepium, L.; Scutellaria galericulata, L.; Plantago decipi- 
ens, Barn.; Chenopodium album, L.; Sueda linearis, Torr., var. 
ramosa, Wats. (S. maritima of Gray’s Manual); Triglochin 
maritimum, L.; Iris versicolor, L.; Ammophila arenarta, Host. 
Erica and Calluna on Nantucket. 
On a visit to Nantucket some years ago, Mrs. Catherine 
Starbuck, the President of the Botanical Society there, showed 
me a locality where I saw the Erica cinerea growing. The spot 
was situated miles from any dwelling. Mrs. Charlotte C. Pear- 
son, an active member of the Society, informed me that she had 
found it when a child, ina locality far from dwellings, and where 
trees had never been known to grow, 
In September of this year Mrs. Pearson sent me a specimen 
of £. cinerea from a new locality, and stated that the plant had 
been found in four different places on the island, far apart. 
Early in October she sent me specimens of Erica Tetralix 
and Calluna vulgaris, informing me that they were found in 
a tract planted with Larches imported from England. I wrote 
asking her to procure all the information. possible as to the 
locality, when she wrote that Mr. Henry Coffin, a gentleman of
