The meadows have been flooded for a fortnight, and this water has been frozen barely thick enough to bear once only. The old ice on the meadows was covered several feet deep. I observed from the bridge, a few rods off northward, what looked like an island directly over the channel. It was the crust of the meadow afloat. I reached [it] with a little risk and found it to be four rods long by one broad,—the surface of the meadow with cranberry vines, etc., all connected and in their natural position, and no ice visible but around its edges. It appeared to be the frozen crust (which was separated from the unfrozen soil as ice is from the water beneath), buoyed up (?), perchance, by the ice around its edges frozen to the stubble. Was there any pure ice under it? Had there been any above it? Will frozen meadow float? Had ice which originally supported it from above melted except about the edges? When the ice melts or the soil thaws, of course it falls to the bottom, wherever it may be. Here is another agent employed in the distribution of plants. I have seen where a smooth shore which I frequented for bathing was in one season strewn with these hummocks, bearing the button-bush with them, which have now changed the character of the shore. There were many rushes and lily-pad stems on the ice. Had the ice formed about them as they grew, broken them off when it floated away, and so they were strewn about on it? _Feb. 26. Wednesday._ Examined the floating meadow again to-day. It is more than a foot thick, the under part much mixed with ice,—ice and muck. It appeared to me that the meadow surface had been heaved by the frost, and then the water had run down and under it, and finally, when the ice rose, lifted it up, wherever there was ice enough mixed with it to float it. I saw large cakes of ice with other large cakes, the latter as big as a table, on top of them. Probably the former rose while the latter were already floating about. The plants scattered about were bulrushes and lily-pad stems. Saw five red-wings and a song sparrow (?) this afternoon. _Feb. 27._ Saw to-day on Pine Hill behind Mr. Joseph Merriam’s house a Norway pine, the first I have seen in Concord. Mr. Gleason pointed it out to me as a singular pine which he did not know the name of. It was a very handsome tree, about twenty-five feet high. E. Wood thinks that he has lost the surface of two acres of his meadow by the ice. Got fifteen cartloads out of a hummock left on another meadow. Blue-joint was introduced into the first meadow where it did not grow before. * * * * *
