The opening of communication with England by the Red Sea route has given to Bombay a great business impetus, and it possesses to-day more elements of future greatness than any other city of Asia. The two principal capitals of the country are situated on opposite sides of the great peninsula, Calcutta being on the Bay of Bengal, and Bombay on the Sea of Arabia. We have in the latter a population of a million and over, one hundred thousand of whom are Parsees, a class of merchants originally from Persia, who represent a large share of the wealth of the city. They are by far the most enterprising and intelligent of the natives of India, and are in entire sympathy with the English government. Socially, they keep to themselves, strictly preserving their well-defined individuality. This people settled here more than eight centuries ago, after their expulsion from Persia. Their temples contain no images, nothing but the altars bearing the sacred fire which their fathers brought with them when they landed here so long ago, and which has never been extinguished, according to their traditions. They worship the sun as the representative of God, and fire in all its forms, as well as the ocean, which would seem to be an antagonistic agent; but as their religion recognizes one good and one evil principle ever contending for the mastery of the universe, perhaps these emblems are no contradiction.

One of the first places to which we are attracted in Bombay is Malabar Hill, a lofty eminence just outside the city. On the top are the five famous "Towers of Silence," which constitute the cemetery of the Parsees. When a death occurs among them, the body is brought here, and after a brief ceremony the corpse is carried into one of the towers, where it is exposed upon a grating. The bearers retire at once, and the door is locked. These towers are open at the top, and on the cornices hundreds of vultures are seen waiting; as soon as the body is left, they swoop down to their awful meal, eagerly tearing and devouring the corpse. The hideous detail is not visible, but the reappearance of those evil birds in a gorged condition is only too significant of what has occurred. The devouring flames which consumed the bodies at Calcutta and at Benares did not shock us like this.

Bombay is made up of fine public buildings, sumptuous dwellings, and low hovels, not mingled indiscriminately, as is often seen in European cities, each class being found clustering in its special locality. In Florence, Rome, or Naples, a half-starved cobbler will be found occupying a stall beneath a palace; but though poverty and riches jostle each other everywhere, the lines of demarcation are more clearly defined in Bombay than elsewhere. A drive along the picturesque shore of the Arabian Sea is an experience never to be forgotten. It will be sure to recall to the traveller the beautiful environs of Genoa, with those winding, rock-cut roads overlooking the Mediterranean Sea. Here the roads are admirably cool and half-embowered in foliage, among which the crimson sagittaria flaunting its fiery leaves and ponderous blossoms, everywhere meets the eye. About the fine villas which are set back a short distance from the roads, delightful gardens of choice flowers are seen, comprising an abundance of tropical plants, tall palms lining the drive-ways up to the houses, where the merchant princes dwell. Most of these are the residences of the Parsees, who in spite of their bigotry and their adherence to ancient superstitions, know how to make their homes beautiful.

In leaving India, a few thoughts naturally suggest themselves. Its history runs back through thousands of years and remotest dynasties, captivating the fancy with numberless ruins, which, while attesting the splendor of their prime, form also the only record of their history. The mosaic character of its population, the peculiarities of its animal kingdom, the luxuriance of its vegetation, the dazzling beauty of its birds and flowers, all crowd upon the memory in charming kaleidoscopic combinations. There can be no doubt of the early grandeur and high civilization of India. To the intellectual eminence of her people we owe the germs of science, philosophy, law, and astronomy. The most perfect of all tongues, the Sanskrit, has been the parent of many others, and now that her lustre has faded, and her children fallen into a condition of sloth and superstition, let us, at least, do her historic justice. Nor should we neglect to heed the lesson she so clearly presents; namely, that nations, like individuals, are subject to the unvarying laws of mutability.

The government of India is a military despotism, England maintaining her rule by force alone over a foreign people numbering four times as many as the whole population of the United States. Order is preserved at a cruel cost of life among an entire race who are totally unrepresented. In travelling from city to city one is not surprised to see many signs of restlessness among the common people, and to hear harsh expressions against British rule. While we recall with a thrill of horror the awful cruelties and the slaughter of human beings during the rebellion of the native race against the English authority in 1857, we do not wonder that a people, so goaded by oppression, should have made a vigorous and bloody struggle to obtain their independence.

We embark at Bombay on a voyage of three thousand miles across the Sea of Arabia and the Indian Ocean, through the Straits of Babelmandeb and the entire length of the Red Sea. The most southerly point of the voyage, taking us within fourteen degrees of the equator, carries us into an extremely warm temperature. The ship holds on her southwest course day after day, lightly fanned by the northeast monsoon, towards the mouth of the Red Sea. At the end of the sixth day we cast anchor at the Peninsula of Aden, a rocky, isolated spot held by English troops, and very properly called the Gibraltar of the Indian Ocean. Like that famous promontory, it was originally little more than a barren rock, which has been improved into a picturesque and habitable place, bristling with British cannon of heavy calibre. It is a spot much dreaded by sailors, the straits being half closed by sunken rocks, besides which the shore is considered to be the most unhealthy spot yet selected by civilized man as a residence. The Arabs call the strait Babelmandeb, that is, the "Gate of Tears," because of the number of vessels which have been wrecked here in the endeavor to enter from the open sea. Aden lies within the rainless zone, so that sometimes the inhabitants see no rainfall for three years together. The remains of an ancient and magnificent system of reservoirs hewn out of the solid rock, are seen here, the construction of which is placed at a date previous to the Christian era, and which have been adapted to modern use.

As we lie at anchor here, there come about the ship a score of young natives, from ten to fifteen years of age. By eloquent gestures, and the use of a few English words, they beg of us to throw small silver coin into the sea, for which they will dive in water that is at least seven fathoms deep. The instant a piece of money is thrown overboard, every canoe becomes emptied, and twenty human beings disappear from sight like a flash. Down, down go the divers, and in the depths struggle together for the trifle, some one of the throng being sure to rise to the surface with the coin displayed between his teeth. Nothing but otters and seals could be keener sighted or more expert in the water.

The general aspect of Aden from the sea, though picturesque, is not inviting, giving one an idea of great barrenness. The mountains and rocks have a peaked appearance, like a spear pointed at one, as much as to say, "better keep off." People who land, however, for the first time, are agreeably disappointed by finding that every opportunity for encouraging the growth of vegetation and imparting its cheerful effect to the hard rocky soil has been carefully improved.

Our course after leaving Aden is nearly north; the headlands of Abyssinia are long visible on our port side, while on the other we have a distant view of Arabia. Jeddah, the seaport of Mecca, with its bright minarets, is to be seen in the distance. In coasting along the shores of Nubia, the dense air from off the land is like a sirocco, suffocatingly hot. Suez is reached at last, a place which is all waste and barrenness, so we hasten on by railway to Cairo, a distance of two hundred miles.
