1. When we go from a big modern manufacturing town into an old town or village, we cannot help noticing the old buildings, the ancient churches, the old town-hall, the alms-houses, and the old houses with their plastered fronts, tiled roofs, and huge chimney-stacks. 2. As years go by, the number of these old houses gets less and less. In the course of time many of the smaller ones especially, which have been neglected and allowed to fall into bad repair, become dangerous to live in. The sanitary inspector and the medical officer of health condemn them as unfit for human habitation, and the houses are shut up. Then, perhaps, they stand empty for some years; mischievous boys throw stones and break the glass left in the queer little windows; bill-posters paste notices of all kinds on the doors, walls, and window-shutters; holes are knocked in the plaster, bits of the woodwork are torn away, chalk-marks are scrawled on the walls, and the buildings very shortly look disgracefully untidy. Then some day the "house-breaker" appears on the scene, and the houses, which have stood for centuries, are cleared away, and modern buildings take their places. 3. Thoughtful people, who know something of the history of the town or village, are always sorry to see old buildings disappear; because there is much to be learned from them, and they help us to recall many things of great value and importance which we very easily lose sight of. 4. But, old as the houses in our streets and villages are, there are very few of them which date back more than three hundred or three hundred and fifty years. Most of them only date back to the time of Queen Elizabeth--the latter part of the sixteenth century. 5. There are, however, a number of fine old houses which have work in them of the thirteenth and fourteenth centuries, and some people can point out to you traces of work in some old houses of an earlier date than that. There is at Lincoln, for instance, a fine old stone house called "the Jew's House", which was built late in the twelfth century. But stone houses for ordinary people, both in towns and villages, were very rare then--wood was the common material. Of course in parts of the country where stone was plentiful and wood scarce, stone would be very largely used. For instance, amongst the Cotswolds stone has always been the handiest material for building walls, and for covering roofs. [Illustration: Norman Dwelling.--The Jew's House, Lincoln] 6. Nowadays, both in town and country, houses are commonly "bunches of bricks". The Romans knew how to make bricks or tiles, and in places near old Roman cities Roman tile is still to be seen, which has been used up over and over again in the walls of old buildings. The big tower of St. Alban's Cathedral is built of Roman tiles which had been used centuries before in the walls of Roman houses in Verulamium. That tower has been standing as it is now for over 800 years.
