bogs, the many fresh ponds, the Great Salt Pond, the meadows, 
the cliffs, and.the shore. One might, indeed, include another 
province, in the range: of the Alga, these, however, from the 
changeable nature of the shore, are not.so abundant as. in many 
places along our coasts. Still we found glorious specimens of 
Ascophyllum, Fucus, and Laminaria. 
Near the beach, of course, one finds Avagallis arvensis, a cos- 
mopolitan plant. Here, too, are Cakile edentula ; the curious sea- 
sand-wort, Arenaria peploides ; sow thistle,. Sonchus asper ; Sueda, 
Salsola,and Solidago sempervirens. The last grows magnificently, 
but was hardly in flower even when I left. I found in‘all seven 
species of golden-rod on the island, as will be seen by the ap- 
pended list. Solidago lanceolata is, I think, the commonest weed 
on the island. It covers whole pastures and fringes every road. 
In some places the S. Caroliniana was about as common. We 
noticed quite a difference in the time of flowering of the two 
species, the last preceding the S. /anceolata by perhaps a week. 
There is the usual host of weeds, among which the wild carrot 
is preéminently first. Chrysanthemum Leucanthemum, is a good 
second. Now and then one meets with a clump of Rudbeckid 
hirta. \t is misnamed “ox-eye” throughout Rhode Island. 
There were four species of thistle, the Canada” being well to the 
front. 
My habit was to jot down in a note book, as I walked, what- 
ever plants I saw, the walk being mainly for the special purpose 
of discovery. I also collected somewhat. For one week, long to 
be remembered by us both, I had the assistance of my young 
friend, Mr. J. F. Collins, of Providence. 
Incidentally we observed the butterflies, finding, to our surprise, 
a large number of specimens of Janonia cenia. Hitherto it has 
been only sporadically found in the State. The abundance of 
Papilio Asterias is explained from the prevalence of Umbelliferz. 
The carrot and Siwm cicutefolium are everywhere. Nothing um- 
belliferous probably ever escapes the larva of Asterias, though I 
never happened to see it on Discopleura, so frequent here. Danais 
Archippus had found out that Asclepias Syriaca was here and 
hung his green and gold chrysalis on the leaves. 
Among the plants new to Rhode Island, we found Potamogeton
