Here is a better case: the leg of a woodcock was sent to me by a friend, with a little cake of dry earth attached to the shank, weighing only nine grains; and this contained a seed of the toad-rush (Juncus bufonius) which germinated and flowered.

as large as the seed of a vetch. ↑ Thus seeds might occasionally be transported to great distances; for many facts could be given showing that soil almost

is charged with seeds. Reflect for a moment on the millions of quails which annually cross the Mediterranean; and can we doubt that the earth adhering to their feet would sometimes include a few minute seeds? But I shall

As icebergs are known to be sometimes loaded with earth and stones, and have even carried brushwood, bones, and the nest of a land-bird,

can hardly

that they must

In the Azores, from the large number of →the species of plants common to Europe, in comparison with the →plants of other oceanic islands nearer to the mainland, and (as remarked by Mr. H. C. Watson) from

Mr.

Hartung to inquire whether he had observed erratic boulders on these islands, and he answered that he had found large fragments of granite and other rocks, which do not occur in the archipelago. Hence we may safely infer that icebergs formerly landed their rocky burthens on the shores of these mid-ocean
