In their earliest stages they are still without a floor and are roofed with thatch or shingle. Towns often thus remain like early Sydney, "a mere assemblage of paltry erections intermediate between the hut and the house." The architecture is of the simplest. A "butt" and a "ben," with a "lean-to," form the prevailing type. As the family grows or its wealth increases, new portions are added, till many colonial houses look for all the world as if they had "come out in penny numbers." Even with a few stately structures--luxurious mansions, extensive government offices, Gothic parliamentary buildings--a wooden city has an indefinable meanness of appearance. It is improved out of existence by the dread agency of fire. Like Charles's London, New Orleans and many another colonial town have thus had an Augustan renewal. Houses are now built of brick, stone, or concrete; tile, slate, and iron replaced thatch and shingle; two stories were ventured on; chimneys were smaller but safer. They became susceptible of architecture: Spanish features were introduced into those of New Orleans; the more northern colonies copied the English country house, with modifications to suit the hotter or colder climate; and in New South Wales a taste for mansion-building came into vogue along with splendid equipages, liveried servants, and pedigrees. Such houses were at first arranged in all degrees of irregularity and confusion. The street is a modern invention. The cows returning from pasture laid out Boston, and the bullock teams climbing up from the harbor charted Sydney. Towns in manufactured colonies, as Savannah, Augusta, most South American cities, Christchurch and Invercargill in New Zealand, were planned before settlement and have their streets at right angles. A hundred years ago Talleyrand, exiled in the United States, described the journey from one of these cities to the interior as successively exhibiting all past stages of the human habitation from the mansion to the tent, and just a century later one of Talleyrand's countrymen, M. Pierre Leroy-Beaulieu, traveling in the reverse direction, from "the bush" to Coolgardie, witnessed the gradual transformation of the tent into the two-storied hotel. A great part of the history of the race in the matter of habitations is thus museumed in the space of a few miles.
