wholly so—one would naturally think that here the food sought for is not the seaweed itself, but any live things that may be clinging to it. This, accordingly, was my provisional hypothesis, but practical investigation hardly supported it, for on examining some of the seaweed, first in one spot and then another, along the track in which the birds had swum, I could find nothing whatever upon it—noticeably bare, indeed, it was. The eyes of an eider-duck are, no doubt, sharper than my own—or anybody's. Still I do not believe that even the most sharp-sighted one could find anything on this seaweed, at least without searching for it, whereas these ducklings are constantly dipping and, apparently, as constantly feeding all the way along. Finding always, they never have the appearance of looking for what they find. To me they seem to be browsing in their little ducking way, just as sheep browse in a field.
The seaweed here is not the long, brown sort, but another and almost equally common kind, which is shorter and covered with little lobes, shaped something like an orange-pip, but of a slightly larger size—small grapes, perhaps, since they grow in bunches, is more what they resemble. They are full of a clear, gelatinous substance that might well be appreciated, and having, to the boot of all the other indications, actually seen something that looked very like one of them in the beak of a duckling, I imagine—and it is a pleasing imagination—that the latter, at any rate, derive some part of their sustenance from these their
