The Beach-grass is “two to four feet high, of a seagreen color,” and it is said to be widely diffused over the world. In the Hebrides it is used for mats, pack-saddles, bags, hats, etc.; paper has been made of it at Dorchester in this State, and cattle eat it when tender. It has heads somewhat like rye, from six inches to a foot in length, and it is propagated both by roots and seeds. To express its love for sand, some botanists have called it _Psamma arenaria_, which is the Greek for sand, qualified by the Latin for sandy,—or sandy sand. As it is blown about by the wind, while it is held fast by its roots, it describes myriad circles in the sand as accurately as if they were made by compasses. It was the dreariest scenery imaginable. The only animals which we saw on the sand at that time were spiders, which are to be found almost everywhere whether on snow or ice-water or sand,—and a venomous-looking, long, narrow worm, one of the myriapods, or thousand-legs. We were surprised to see spider-holes in that flowing sand with an edge as firm as that of a stoned well. In June this sand was scored with the tracks of turtles both large and small, which had been out in the night, leading to and from the swamps. I was told by a _terræ filius_ who has a “farm” on the edge of the desert, and is familiar with the fame of Provincetown, that one man had caught twenty-five snapping-turtles there the previous spring. His own method of catching them was to put a toad on a mackerel-hook and cast it into a pond, tying the line to a stump or stake on shore. Invariably the turtle when hooked crawled up the line to the stump, and was found waiting there by his captor, however long afterward. He also said that minks, muskrats, foxes, coons, and wild mice were found there, but no squirrels. We heard of sea-turtle as large as a barrel being found on the beach and on East Harbor marsh, but whether they were native there, or had been lost out of some vessel, did not appear. Perhaps they were the Salt-water Terrapin, or else the Smooth Terrapin, found thus far north. Many toads were met with where there was nothing but sand and beach-grass. In Truro I had been surprised at the number of large light-colored toads everywhere hopping over the dry and sandy fields, their color corresponding to that of the sand. Snakes also are common on these pure sand beaches, and I have never been so much troubled by mosquitoes as in such localities. At the same season strawberries grew there abundantly in the little hollows on the edge of the desert standing amid the beach-grass in the sand, and the fruit of the shadbush or Amelanchier, which the inhabitants call Josh-pears (some think from juicy?), is very abundant on the hills. I fell in with an obliging man who conducted me to the best locality for strawberries. He said that he would not have shown me the place if he had not seen that I was a stranger, and could not anticipate him another year; I
