In addition to the fever for improvement, Boston owes the loss of many of her time-hallowed buildings to a more disastrous agency--that of the conflagrations which have visited her with strange frequency. A fire in 1811, which swept away the little house on Milk street where Franklin was born--and which is now occupied by the Boston _Post_--another in 1874, in which more than one hundred buildings were destroyed; and the "Great Boston Fire" of 1872, followed by conflagrations in 1873, 1874, 1877 and 1878, seemed to indicate that the fire fiend had selected Boston as his especial prey. To the terrible fire of 1872 many precious lives, property valued at eighty millions of dollars, and the entire section of the city enclosed by Summer, Washington, Milk and Broad streets were sacrificed. The scene was one a witness never could forget. Mingled with the alarum of the fire-bells and the screams and shouts of a fear-stricken people came the sound of terrific explosions, those of the buildings which were blown up in the hope of thus "starving out" the fire by making gaps which it could not overstep, and to still further complete the desolation, the gas was shut off, leaving the city in a horror of darkness; but the flames swept on like a pursuing Fury, wrapping the doomed city still closer in her embrace of death, and who was not satisfied until she had left the business centre of Boston a charred and blackened ruin. This same district is to-day, however, the most prosperous and architecturally prepossessing of the business sections of the city, practically illustrating another phase of that same spirit of improvement and civic pride which has overturned so many ancient idols and to-day threatens others. Indeed, it would be a churlish disposition which would lament the disappearance of the old edifices, the straightening of the thoroughfares, the alterations without number which have taken place, and which have resulted in the Boston of to-day, one of the most beautiful, prosperous and public-spirited cities in the world. The intelligence and local loyalty, for which her citizens are renowned, have been set to work to attain one object--the modest goal of perfection. Obstacles which some cities might have contentedly accepted as unavoidable have been swept away; advantages with which other cities might have been satisfied have been still further extended and improved. The 783 acres originally purchased by the settlers of Boston from William Blaxton for £30 has been increased over thirty times, until the city limits comprise 23,661 acres; this not by magic as it would seem, but by annexation of adjoining boroughs--Roxbury, Dorchester, Charlestown, and others--and by reclamation of the seemingly hopeless marshy land to the north and south of the city. The "Back-Bay" district, the very centre of Boston's wealth, fashion and refinement, the handsomest residence quarter in America, is built upon this "made land,"
