At Beauvois--The magnificent old houses supported on columns of workmanship (so far as I recollect) unique in the north of France, at the corner of the market-place, have recently been destroyed for the enlarging of some ironmongery and grocery warehouses. The arch across the street leading to the cathedral has been destroyed also, for what purpose, I know not. At Rouen--The last of the characteristic houses on the quay is now disappearing. When I was last there, I witnessed the destruction of the noble gothic portal of the church of St. Nicholas, whose position interfered with the courtyard of an hotel; the greater part of the ancient churches are used as smithies, or warehouses for goods. So also at Tours (St. Julien). One of the most interesting and superb pieces of middle-age domestic architecture in Europe, opposite the west front of the cathedral, is occupied as a cafe, and its lower story concealed by painted wainscotings; representing, if I recollect right, twopenny rolls surrounded by circles of admiring cherubs. At Geneva--The wooden projections or loggias which were once the characteristic feature of the city, have been entirely removed within the last ten years. At Pisa--The old Baptistery is at this present time in process of being "restored," that is, dashed to pieces, and common stone painted black and varnished, substituted for its black marble. In the Campo Santo, the invaluable frescoes, which might be protected by merely glazing the arcades, are left exposed to wind and weather. While I was there last year I saw a monument put up against the lower part of the wall, to some private person; the bricklayers knocked out a large space of the lower brickwork, with what beneficial effect to the loose and blistered stucco on which the frescoes are painted above, I leave the reader to imagine; inserted the tablet, and then plastered over the marks of the insertion, destroying a portion of the border of one of the paintings. The greater part of Giotto's "Satan before God," has been destroyed by the recent insertion of one of the beams of the roof. The tomb of Antonio Puccinello, which was the last actually put up against the frescoes, and which destroyed the terminal subject of the Giotto series, bears date 1808. It has been proposed (or at least it is so reported) that the church of La Spina should be destroyed in order to widen the quay.
