Aristocracy is a queer thing in Australia. Many of those now claiming "respectability" and holding themselves aloof from the members of the settlements did not have their expenses paid out by government, because they were born on the island--not convicts, but only the offspring of those who were. In the race for wealth educated and refined gentlemen are generally outstripped by those who with less mind have greater physical strength, more practical knowledge of the world and more tact in overcoming difficulties; so that one meets wealthy miners who cannot write their own names, and learned bootblacks and cooks who have taken their degrees in mathematics and the languages. One millionaire who had a fancy to be thought literary sent regular contributions to the English magazines, every line of which was written by his footman, to whom he paid an enormous salary, not so much for writing as for keeping his secret, and it was years before it leaked out. In the struggle for position the man of gold gains the day, and not unfrequently brute force or unscrupulous trickery is called in to keep that which wealth has purchased. Melbourne is the commercial metropolis of Australia, as Sydney is the capital of the penal colony, and though both are large, well-built and thriving cities, they are strikingly in contrast with each other. One is the scion of a lordly house, "to the manner born"--the other, the _parvenu_ of yesterday, whose gold makes his position. Melbourne is to all intents a European city, with its boulevards and regular streets, whole blocks of costly stores and princely dwellings, and environed by elegant villas and country-seats adorned with gardens, vineyards and choice shrubbery. It has its English and Chinese quarters, the latter as essentially Chinese as if built in the Celestials' own land, and brought over, mandarin buttons, tiny teapots, opium-pipes and all, in one of their own junks. The English quarter contains, besides the government buildings, several schools, hospitals, churches and benevolent institutions, the public library, a polytechnic hall, a national museum, theatres and opera-houses, all built in a style alike elegant and substantial. The library only ten years after it was opened numbered 41,000 volumes, and has since been largely increased. Science rather than literature, and practical utility more than entertainment, have been kept in the ascendency in the management of this institution. The hall is open for daily lectures, and some valuable telescopes and other apparatus belong to the institution. The cabinet of natural history contains many rare specimens that serve to elucidate the ancient and modern history of the country, especially in regard to some of the animals and vegetables indigenous to the island. The museum is built on a commanding eminence, and from its spacious windows one sees clearly to the opposite side of Hobson's Bay. [Illustration: THE ENVIRONS OF MELBOURNE.]
