“I had now made four different visits to the cave, traveling, according to the reckoning of my guide, about fifty-four miles. Very few visitors explore it as thoroughly, and yet I had not gone over one-third of the space that has already been explored. The guide says that two hundred and fifty different avenues are already known, measuring the distance of one hundred and sixty-five miles. The temperature of the cave is uniformly about fifty-five degrees, and its bracing, invigorating character may be judged from the fact that ladies, some of them quite delicate, are constantly taking this ‘long route,’ traveling a greater number of miles than most men would think of going on foot above ground.

“We felt but little fatigue from our rough, clambering walk of some twenty miles, until we emerged from the cave, and came in contact with outer air. After breathing the air of the cave from eight A. M. till five P. M., the atmosphere seemed very impure. We could smell every tree, and plant, and old log; and the air was so sultry and sickening, that we had to rest awhile at the mouth before starting for the hotel, some fifty rods distant.

“I have thus attempted to redeem my promise in regard to writing you from the cave. I had no thought of writing at so great length. If the cave were possessed of mind and sensibility, I would take off my hat to it, and feelingly ask its pardon for the great injustice I have done it in these letters. But as it is, I will only say that I have over and over again assented to the truthfulness and justice of my guide Alfred’s idea of all descriptions of the cave: ‘Writin don’t do no good. If anybody wants to know how the cave looks, they must come and see it.’ And I can not conceive of any journey for this purpose so long and toilsome, that those making it would not be abundantly compensated for their pains, by a view of this wonderful work of a wonder-working God.”

Still another visitor, writing to a friend in Europe, says of this wonderful cave, “I had heard and read descriptions of it, long since; but the half, the quarter, was not told. Its vastness, its lofty arches, its immense reach into the bosom of the solid earth, fill me with astonishment. It is, like Mont Blanc, Chimborazo, and the falls of Niagara, one of God’s mightiest works. Shall I compare it with anything of a similar description, which you have seen on the other side of the Atlantic? with the grotto of Neptune, or that of the Sibyl, at Tivoli, or with any of Virgil’s poetic Italian machinery? No comparison can be instituted. I speak, as you are aware, from personal knowledge. You, seated on the opposite bank of the Arno, have seen me clamber up, from the noisy waters below, to the entrance of the far-famed grotto of Neptune, which I leisurely explored. In point of capaciousness, that grotto has little more to boast of than the cellar of a large hotel, and, like that, was, as I think, excavated by human hands. That of the Tiburtine Sibyl is still more limited in its dimensions. Indeed, every cavern which I have ever seen, if placed along side of this, would dwindle into insignificance.”

The same writer says, “I can not refrain from giving you an account of an incident that happened in this cave last spring. A wedding party went to the cave to spend the honeymoon. While there, they went to visit those beautiful portions of the cave which lie beyond the river ‘Jordan.’ In order to do this, a person has to sail down the river nearly a mile before reaching the avenue which leads off from the river on the opposite side, for there is no shore, or landing-place, between the point above on this side, where you come to the river, and that below on the other; for the river fills the whole width of one avenue of the cave, and is several feet deep where the side walls descend into the water. This party had descended the river, visited the cave beyond, and had again embarked on the water for their return homeward. After they had ascended the river about half-way, some of the party, who were in a high glee, got into a romp and overturned the boat. Their lights were all extinguished, their matches wet, the boat filled with water and sunk immediately; and there they were, in ‘the blackness of darkness,’ up to their chins in water. No doubt, they would all have been lost, had it not been for the guide’s great presence of mind. He charged them to remain perfectly still; for, if they moved a single step, they might get out of their depth in water; and swimming would not avail them, for they could not see where to swim to. He knew that, if they could bear the coldness of the water any length of time, they would be safe; for another guide would be sent from the cave house, to see what had become of them. And in this perilous condition, up to their mouths in water, in the midst of darkness ‘more than night,’ four miles under ground, they remained for upward of five hours; at the end of which time, another guide came to their relief. Matthew, or Mat, the guide who rescued them, told me that, when he got to where they were, his fellow-guide, Stephen, (the Columbus of the cave,) was swimming around the rest of the party, cheering them, and directing his movements, while swimming, by the sound of their voices, which were raised, one and all, in prayer and supplication for deliverance!”

In conclusion it may be interesting to state, that Colonel Croghan, to whose family the Mammoth cave belongs, was a resident of Louisville, Kentucky. He went to Europe some twenty years ago, and found himself frequently questioned of the wonders of the Mammoth cave, a place he had never visited, and of which he had heard but little at home, though living within ninety miles of it. He went there on his return, and the idea struck him to purchase it, and make it a family inheritance. In fifteen minutes’ bargaining he bought it for ten thousand dollars, and shortly after he was offered one hundred thousand dollars for his purchase. In his will he tied it up in such a way that it must remain in his family for two generations, thus appending its celebrity to his name. There are nineteen hundred acres in the estate, though the cave probably runs under the property of a great number of other land owners. For fear of those who might dig down and establish an entrance to the cave on their own property, (a man’s farm extending up to the zenith and down to the nadir,) great vigilance is exercised to prevent such subterranean surveys and measurements as would enable one to sink a shaft with any certainty. The cave extends ten or twelve miles in several directions, and there is probably many a back-woodsman sitting in his hut within ten miles of the cave, quite unconscious that the most fashionable ladies and gentlemen of Europe and America are walking without leave under his potatoes and corn.

THE GREAT CAVERN OF GUACHARO.

Passing from the Mammoth cave in North America, let us next notice the great cavern of Guacharo in South America, as described in the narrative of Humboldt, which is abridged in the account that follows.

“In a country where the people are fond of the marvelous, a cavern that gives birth to a river, and which is inhabited by thousands of nocturnal birds, the fat of which is used to dress the food of the inhabitants, is a ceaseless topic of conversation and discussion. Scarcely has a stranger arrived at Cumana, when he is told of the stone of Araya for the eyes; of the laborer of Arenas who suckled his child; and of the cavern of Guacharo, which is said to be several leagues in length; till he is tired of hearing of them.

“The Cueva del Guacharo is pierced in the vertical profile of a rock. The entrance is toward the south, and forms a vault eighty feet broad, and seventy-two feet high. The rock, that surmounts the grotto, is covered with trees of gigantic hight. The mammee-tree, and the genipa with large and shining leaves, raise their branches vertically toward the sky; while those of the courbaril and the erythrina form, as they extend themselves, a thick vault of verdure. Plants of the family of pothos with succulent stems, oxalises, and orchideæ of a singular structure, rise in the driest cliffs of the rocks; while creeping plants, waving in the winds, are interwoven in festoons before the opening of the cavern. We distinguished in these festoons a bignonia of a violet blue, the purple dolichos, and for the first time that magnificent olandra, the orange flower of which has a fleshy tube more than four inches long. The entrances of grottos, like the view of cascades, derive their principal charm from the situation, more or less majestic, in which they are placed, and which in some sort determines the character of the landscape. What a contrast between the Cueva of Caripe, and those caverns of the north crowned with oaks and gloomy larch-trees!
