The buildings in Adelaide show well. A very white freestone has entered largely into the more recent erections; and, as there are comparatively few large factories in the city, and no shipping nearer than Port Adelaide, they lose but little of their pristine freshness by smoke and grime. Then the unpleasant effect produced by the sight of a hovel adjoining a palatial bank or pile of warehouses several storeys high, is of rare occurrence, while the broad streets offer the most advantageous conditions for the display of the various architectural styles employed. The town has been called 'the city of churches;' and the number of ecclesiastical edifices which it contains places its pretensions to that distinction beyond question. The Anglican Cathedral of St. Peter is a large and imposing building, a portion of which is still uncompleted, occupying an elevated position in the southern portion of North Adelaide. The Roman Catholic Cathedral of St. Francis Xavier is in the south, and recalls the early days of the colony, when the prophecies of its future importance were few in number. All the other great religious bodies are also creditably represented. Nearly all the Government departments are in the vicinity of Victoria Square, an ornamental reserve, through which King William Street, one of the most handsome thoroughfares in Australia, has been carried. No traveller should leave Adelaide without spending some hours in the Botanical Garden. To omit that lovely resort would be an error indeed. [Illustration: AN ADELAIDE PUBLIC SCHOOL.] South Australia contains a little over 300,000 inhabitants. Its chief industries are agricultural, pastoral, and mining. Very early in its history it became the granary of the colonies, and, although it can no longer claim that distinction, it is still one of the few places in the world where the visitor can travel over three hundred miles in the same direction between fields of waving yellow corn. Despite the small returns from wheat-growing, the area under cultivation is enlarged every year, and is now not less than two million acres. More attention is being paid to scientific farming, thanks to the influence of the recently established Agricultural College at Roseworthy, thirty miles north of Adelaide, experimental farms in various parts of the colony, and the lectures delivered in the chief agricultural centres. The yield is so dependent on the rainfall that the average for the colony rarely exceeds ten bushels per acre, and occasionally falls below three. The subject of irrigation has lately been warmly taken up by the agricultural community, and the next few years will see not only a more rational system of farming, but the adoption of means to render that community less dependent on the uncertain rainfall. At the London Exhibition a splendid sample of wheat grown at Mount Barker--a beautifully situated township amongst the hills, twenty miles south-east of Adelaide--obtained the highest award.
