A western savant, having investigated the parasites existing in hogs, affirms that in western pork, eight animals out of every one hundred are affected by that muscle-boring pest so dangerous to those who have eaten the infected meat, and so well known to all students as the Trichina spiralis. The distinguished writer Letheby says of this parasite: "As found in the human subject (after death) it is usually in the encysted state, when it has passed beyond its dangerous condition, and has become harmless. In most cases, when thus discovered, there is no record of its action, and therefore it was once thought to be an innocent visitor; but we now know that while it was free, (that is, before nature had barricaded it up in the little cyst,) its presence was the cause of frightful disorders, killing about fifty per centum of its victims in terrible agony. The young worms having hatched in the body of man, migrate to the numerous muscles, causing the most excruciating pain, so that the patient, fearing to move his inflamed muscles, would lie motionless upon his back, and if he did not die in this state of the disorder, nature came to the rescue and imprisoned the creature by surrounding it with a fibrous cyst, where it lives for years, being ready at any moment to acquire activity when it is swallowed and released from its cell."

Another parasite found in the muscles of the pig is known as the Cysticercus cellulosus, and the animals afflicted by it are said to have the measles. This larva of the tapeworm exists in the pig in little sacs not larger than a pin's head, and can be seen by the naked eye. The strong brine of the packer does not kill them, and I have known them to be taken alive from a boiled ham. The great heat of frying alone renders them harmless. When partially-cooked, measly pork is eaten by man, the gastric juice of the stomach dissolves the membranous sac which contains the living larva, and the animal soon passes into the intestines, where, clinging by its hooks, it holds on with wonderful tenacity, rapidly sending out joint after joint, until the perfect tapeworm sometimes attains a length of thirty feet.

Let us hope, for the credit of humanity, that these facts are not generally known, for man has ills enough without incurring the risks of such a diet. If pork must form a staple, let the genealogical tree of his pigship be carefully sought after, and let the would-be consumer ask the question considered so important in a certain river- bounded city of Pennsylvania, "Who was his grandfather?"

In the year 1800 Cincinnati was a little pioneer settlement of seven hundred and fifty men, women, and children. Her census of 1880 will not fall far short of a quarter of a million. She contributes more than her share to feed the world, and is, strange to say, as celebrated for the terpsichorean art as for her pork. Even Boston must yield her the palm as a musical centre, and give to the inhabitants of the once rough western city the credit due them for their versatility of talent, and the ease with which they render Beethoven, or "take a turn in pork," as occasion may demand, many of the music-loving citizens being engaged at times in a commercial way with this staple.

Having obtained at a bookstore a copy of Lloyd's Map of the Mississippi River, I returned to the tailor's, where I was greeted in the most kindly manner, and informed that the young lady of the house, the only daughter of my host, had voluntarily left home to visit some city relations, that I might occupy her comfortably furnished room, with the open fireplace, which was now filled with blazing wood, and sending forth a genial glow into the heavily-curtained apartment. When I protested against this promotion in the social scale, and refused to deprive the young lady of her room, I was informed that she knew "WHO WAS WHO," and had insisted upon leaving her room that a gentleman might be properly entertained in it. From this time my now agreeable host stoutly refused to accept payment in advance for my daily rations, while, with his family and apprentices, he took up his quarters each evening in my new room, relating his experiences during the war, and giving me many original ideas.

It grew warmer, but the ice of the creek in which my boat lay did not melt. The water was, however, falling, and it became necessary to cut out the sneak-box, and slide her over the ice into the unfrozen Ohio. My host had become alarmed, and kept an anxious eye upon the boat. "De peoples knows de poat is here, and some of dem hab told others about it. If you don't hide her down de rivver to-night, she will be stolen by de rivver thieves." I was thus forced to leave these kind people, who about noon escorted me to the duck-boat, and showered upon me their best wishes for a prosperous voyage. It was a glorious afternoon, and the sun poured all his wealth of light and cheerfulness upon the valley.

Late in the day I passed the mouth of the Big Miami River. Indiana was on the right, while Kentucky still skirted the left bank of the river. The state of Ohio had furnished the Ohio River with a margin for four hundred and seventy-five miles. The Little Miami River joins the Ohio six miles above Cincinnati; the Big Miami enters it twenty miles below the city. These streams flow through rich farming regions, but they are not navigable. After passing the town of Aurora, which is six miles below the Big Miami, I caught sight of the mouth of a creek, whose thickets of trees, in the gloom of the fast approaching night, almost hid from view the outlines of a forlorn-looking shanty-boat. Clouds of smoke, with the bright glare of the fire, shot out of the rusty stove-pipe in the roof, but I soon discovered that it was the abode of one who attended strictly to his own business, and expected the same behavior from his neighbors. So, saying good evening to this man of solitary habits, I quickly rowed past his floating hermitage into the darkness of the neighboring swamp. I soon put my own home in order, ate my supper, and retired, feeling happy in the thought that I should before long reach a climate where my out-door life would not be attended with so many inconveniences.

The next day a milder but damper atmosphere greeted me. By noon I had rowed twenty-two miles, and was off the mouth of Big Bone Lick Creek, in Kentucky. Two miles from the mouth of this creek are some springs, the waters of which are charged with sulphur and salt. The most interesting feature of this locality was the fact that here were buried in one vast bed the fossil bones of "The Mastodon and the Arctic Elephant." Formerly these prehistoric relics of a departed fauna were scattered over the surface of the earth. The first mention of this locality was made, I think, by a French explorer in 1649. It is again referred to by a British subject in 1765. A rare copy of a private journal kept by this early explorer of the Ohio, Colonel George Croghan, was published in G. W. Featherstonhaugh's "American Journal of Geology," of December, 1831. This monthly publication ended with its first year's existence. Only five copies of this number were known to be in print three years since, when Professor Thomas, of Mount Holly, New Jersey, encouraged the issue of a reprint of one hundred copies, from which some of our public libraries have been supplied.

This Colonel George Croghan, in company with deputies from the Seneca, Shawnesse, and Delaware nations, left Fort Pitt (Pittsburgh), in two bateaux, on the 15th of May, 1765, bound on a mission to the Indian tribes of the Ohio valley. On the 29th of the month the expedition reached the Little Miami River. Colonel Croghan there commences his account of the Big Bone Lick region. He says: "May 30th we passed the Great Miami River, about thirty miles from the little river of that name, and in the EVENING arrived at the place WHERE THE ELEPHANTS' BONES ARE FOUND, when we encamped, intending to take a view of the place next morning. This day we came about seventy miles. The country on both sides level, and rich bottoms, well watered. May 31st. Early in the morning we went to the great Lick, where those bones are only found, about four miles from the river, on the south-east side. In our way we passed through a fine-timbered, clear wood: we passed into a large road, which the buffaloes have beaten, spacious enough for two wagons to go abreast, and leading straight into the Lick. It appears that there are vast quantities of these bones lying five or six feet under ground, which we discovered in the bank at the edge of the Lick. We found here two tusks above six feet long; we carried one, with some other bones, to our boat, and set off."

In relation to the aboriginal inhabitants of the country of the Ohio valley, it is interesting to note that the "Six Nations" held six of the gates to New York, and were strong because they were united, for Colonel Croghan's enumeration of them shows that they had only two thousand one hundred and twenty fighting-men, and were never supported by more than about two thousand warriors from tributary tribes, when at war with the whites.
