The shadbush, (Amelanchier,) beach-plums, and blueberries, (Vaccinium Pennsylvanicum,) like the apple-trees and oaks, were very dwarfish, spreading over the sand, but at the same time very fruitful. The blueberry was but an inch or two high, and its fruit often rested on the ground, so that you did not suspect the presence of the bushes, even on those bare hills, until you were treading on them. I thought that this fertility must be owing mainly to the abundance of moisture in the atmosphere, for I observed that what little grass there was was remarkably laden with dew in the morning, and in summer dense imprisoning fogs frequently last till mid-day, turning one's beard into a wet napkin about his throat, and the oldest inhabitant may lose his way within a stone's-throw of his house, or be obliged to follow the beach for a guide. The brick house attached to the light-house was exceedingly damp at that season, and writing-paper lost all its stiffness in it. It was impossible to dry your towel after bathing, or to press flowers without their mildewing. The air was so moist that we rarely wished to drink, though we could at all times taste the salt on our lips. Salt was rarely used at table, and our host told us that his cattle invariably refused it when it was offered them, they got so much with their grass and at every breath; but he said that a sick horse, or one just from the country, would sometimes take a hearty draught of salt water, and seemed to like it and be the better for it.

It was surprising to see how much water was contained in the terminal bud of the sea-side golden-rod, standing in the sand early in July, and also how turnips, beets, carrots, etc., flourished even in pure sand. A man travelling by the shore near there not long before us noticed something green growing in the pure sand of the beach, just at high-water mark, and on approaching found it to be a bed of beets flourishing vigorously, probably from seed washed out of the Franklin. Also beets and turnips came up in the sea-weed used for manure in many parts of the Cape. This suggests how various plants may have been dispersed over the world to distant islands and continents. Vessels, with seeds in their cargoes, destined for particular ports, where perhaps they were not needed, have been cast away on desolate islands, and though their crews perished, some of their seeds have been preserved. Out of many kinds a few would find a soil and climate adapted to them, become naturalized, and perhaps drive out the native plants at last, and so fit the land for the habitation of man. It is an ill wind that blows nobody any good, and for the time lamentable shipwrecks may thus contribute a new vegetable to a continent's stock, and prove on the whole a lasting blessing to its inhabitants. Or winds and currents might effect the same without the intervention of man. What, indeed, are the various succulent plants which grow on the beach but such beds of beets and turnips, sprung originally from seeds which perhaps were cast on the waters for this end, though we do not know the Franklin which they came out of? In ancient times some Mr. Bell (?) was sailing this way in his ark with seeds of rocket, saltwort, sandwort, beach-grass, samphire, bayberry, poverty-grass, etc.
