pretty Polygala polygama, spreading ray-wise flat on the ground, white pasture-thistles, (Cirsium pumilum,) and amid the shrubbery the Smilax glauca, which is commonly said not to grow so far north. Near the edge of the banks about half a mile southward, the broom-crowberry, (Empetrum Conradii,) for which Plymouth is the only locality in Massachusetts usually named, forms pretty green mounds four or five feet in diameter by one foot high,—soft, springy beds for the wayfarer: I saw it afterward in Provincetown. But prettiest of all, the scarlet pimpernel, or poor-man's weather-glass, (Anagallis arvensis,) greets you in fair weather on almost every square yard of sand. From Yarmouth I have received the Chrysopsis falcata, (golden aster,) and Vaccinium stamineum, (deer-berry or squaw-huckleberry,) with fruit not edible, sometimes as large as a cranberry (Sept. 7).

The Highland Light-house,[A] where we were staying, is a substantial-looking building of brick, painted white, and surmounted by an iron cap. Attached to it is the dwelling of the keeper, one story high, also of brick, and built by Government. As we were going to spend the night in a light-house, we wished to make the most of so novel an experience, and therefore told our host that we should like to accompany him when he went to light up. At rather early candle-light he lighted a small Japan lamp, allowing it to smoke rather more than we like on ordinary occasions, and told us to follow him. He led the way first through his bedroom, which was placed nearest to the light-house, and then through a long, narrow, covered passage-way, between whitewashed walls, like a prison-entry, into the lower part of the light-house, where many great butts of oil were arranged around; thence we ascended by a winding and open iron stairway, with a steadily increasing scent of oil and lamp-smoke, to a trap-door in an iron floor, and through this into the lantern. It was a neat building, with everything in apple-pie order, and no danger of anything rusting there for want of oil. The light consisted of fifteen argand lamps, placed within smooth concave reflectors twenty-one inches in diameter, and arranged in two horizontal circles one above the other, facing every way excepting directly down the Cape. These were surrounded, at a distance of two or three feet, by large plate-glass windows, which defied the storms, with iron sashes, on which rested the iron cap. All the iron work, except the floor, was painted white. And thus the light-house was completed. We walked slowly round in that narrow space as the keeper lighted each lamp in succession, conversing with him at the same moment that many a sailor on the deep witnessed the lighting of the Highland Light. His duty was to fill and trim and light his lamps, and keep bright the reflectors. He filled them every morning, and trimmed them commonly once in the course of the night. He complained of the quality of the oil which was furnished. This house consumes about eight hundred gallons in a year, which cost not far from one dollar a gallon; but perhaps a few lives would be saved, if better oil were provided. Another light-house keeper said that the same proportion of winter-strained oil was sent to the southernmost light-house in the Union as to the most northern. Formerly, when this light-house had windows with small and thin panes, a severe storm would sometimes break the glass, and then they were obliged to put up a wooden shutter in haste to save their lights and reflectors,—and sometimes in tempests, when the mariner stood most in need of their guidance, they had thus nearly converted the light-house into a dark-lantern, which emitted only a few feeble rays, and those commonly on the land or lee side. He spoke of the anxiety and sense of responsibility which he felt in cold and stormy nights in the winter, when he knew that many a poor fellow was depending on him, and his lamps burned dimly, the oil being chilled. Sometimes he was obliged to warm the oil in a kettle in his house at midnight, and fill his lamps over again,—for he could not have a fire in the light-house, it produced such a sweat on the windows. His successor told me that he could not keep too hot a fire in such a case. All this because the oil was poor. A government lighting the mariners on its wintry coast with summer-strained oil, to save expense! That were surely a summer-strained mercy!

This keeper's successor, who kindly entertained me the next year, stated that one extremely cold night, when this and all the neighboring lights were burning summer oil, but he had been provident enough to reserve a little winter oil against emergencies, he was waked up with anxiety, and found that his oil was congealed, and his lights almost extinguished; and when, after many hours' exertion, he had succeeded in replenishing his reservoirs with winter oil at the wick-end, and with difficulty had made them burn, he looked out, and found that the other lights in the neighborhood, which were usually visible to him, had gone out, and he heard afterward that the Pamet River and Billingsgate Lights also had been extinguished.

Our host said that the frost, too, on the windows caused him much trouble, and in sultry summer nights the moths covered them and dimmed his lights; sometimes even small birds flew against the thick plate-glass, and were found on the ground beneath in the morning with their necks broken. In the spring of 1855 he found nineteen small yellow-birds, perhaps goldfinches or myrtle-birds, thus lying dead around the light-house; and sometimes in the fall he had seen where a golden plover had struck the glass in the night, and left the down and the fatty part of its breast on it.

Thus he struggled, by every method, to keep his light shining before men. Surely the light-house keeper has a responsible, if an easy, office. When his lamp goes out, he goes out; or, at most, only one such accident is pardoned.

I thought it a pity that some poor student did not live there, to profit by all that light, since he would not rob the mariner. "Well," he said, "I do sometimes come up here and read the newspaper when they are noisy down below." Think of fifteen argand lamps to read the newspaper by! Government oil!—light enough, perchance, to read the Constitution by! I thought that he should read nothing less than his Bible by that light. I had a classmate who fitted for college by the lamps of a light-house, which was more light, methinks, than the University afforded.

When we had come down and walked a dozen rods from the light-house, we found that we could not get the full strength of its light on the narrow strip of land between it and the shore, being too low for the focus, and we saw only so many feeble and rayless stars; but at forty rods inland we could see to read, though we were still indebted to only one lamp. Each reflector sent forth a separate "fan" of light: one shone on the windmill, and one in the hollow, while the intervening spaces were in shadow. This light is said to be visible twenty nautical miles and more, to an observer fifteen feet above the level of the sea. We could see the revolving light at Race Point, the end of the Cape, about nine miles distant, and also the light on Long Point, at the entrance of Provincetown Harbor, and one of the distant Plymouth Harbor Lights, across the Bay, nearly in a range with the last, like a star in the horizon. The keeper thought that the other Plymouth Light was concealed by being exactly in a range with the Long Point Light. He told us that the mariner was sometimes led astray by a mackerel-fisher's lantern, who was afraid of being run down in the night, or even by a cottager's light, mistaking them for some well-known light on
