Excerpt from Report on the Progress and Condition of the U. S. National Museum for the Year Ending June 30, 1907 The progress of the work on the new building for the National Museum has already been described. The bad condition of most of the roofs 011 the present Museum building and the efforts made for their improvement have often been discussed in previous reports. Apart from the corner pavilions and central towers, which contain the work rooms and offices, there are seventeen large exhibition halls, each with its separate roof, though all are connected by intervening metal gutters. Eight of these roofs, covering the same number of ranges which adjoin the outer walls of the buildings, were constructed originally of tin, and have called only for such attention and amount of repair as might customarily have been expected. The other nine roofs, being those over the four main halls, the four courts and the central-rotunda, were, however, built of slate, a material too heavy for the support ing iron framework, and unsuitable for the relatively slight pitch of these roofs. They rapidly deteriorated to such an extent as to act almost like sieves, allowing the rain to penetrate during every storm, with the result of damaging the walls and causing much injury to the contents of the halls. Continuous and expensive repairs proved ineffective. It finally became evident that the only remedy lay in the entire replacement of the slate roofs. III accordance with the plans here tofore explained, these roofs were to be of tin 011 the upper or ex posed surface, with an inner Sheathing of thin Sheet steel. The work was taken up in July, 1906, and continued until winter, during which period five of the roofs were renewed in an entirely satisfactory man ner. It is expected that three of the remainder can be rebuilt dur ing the next fiscal year, leaving only that over the rotunda for the summer of 1908. The completion of this undertaking should place the structural part of the building in even better condition than it was in the beginning. It has, fortunately, been possible to carry 011 this reconstruction without materially disturbing the contents of the halls, or closing to the public more than small areas of the floor at any stage of the work.
