J. W. Egan and J. R. Mullett, Architects.] detail, the extreme meanness and baldness of the attic, in which, for the only time in the building, the openings seem to be arranged with some reference to their uses, and in which accordingly they have a painfully pinched and huddled appearance. In the decorative detail there is apparent a divergency of views between the two architects appointed to carry out the divided halves of the united design. The municipal designer--or possibly it is the county gentleman--has been content to stand upon the ancient ways, and to introduce no detail for which he has not found Ludovican precedent, while his rival is of a more aspiring mind, and has endeavored to carry out the precepts of the late Thomas Jefferson, by classicizing things modern. His excursions are not very daring, and consist mainly in such substitutions as that of an Indian’s head for the antique mask, in a frieze of conventionalized American foliage. He has attained what must be in such an attempt the gratifying success of converting his modern material to a result as dull and lifeless and uninteresting as his prototype. It does not, however, impair the grandiosity of the general effect. This is impaired, not merely by the poverty of design already noted in the attic, but also by the niggardliness shown in dividing the polished granite column of the porticoes into several drums, though monoliths are plainly indicated by their dimensions, and by the general scale of the masonry. The small economy is the more injurious, because a noble regardlessness of expense is of the essence of the architecture, and an integral part of its effectiveness. The most monumental feature of the projected building has never been supplied--a huge arch in the centre of each of the shorter fronts, giving access to the central court, and marking the division between the property of the city and of the county. It is possible that the failure to finish this arch has proceeded from the political conflict that has left its scars upon the building elsewhere. There is an obvious practical difficulty in intrusting the two halves of an arch to rival architects and rival contractors. However that may be, the arch is unbuilt, and the entrance to the central court is a mere rift in the wall. The practical townspeople have seized the opportunity thus presented by the unoccupied space of free quarters for the all-pervading buggy. With a contempt for the constituted authorities that it must be owned the constituted authorities have gone far to justify, they tether their horses in the shadow of their chief civic monument, like so many Arabs under the pillars of Palmyra or Persepolis, and heighten the impression of being the relic of an extinct race that is given to the pile not only by its unfinished state and by the stains of smoke, undistinguishable from those of time, but by its entirely exotic architecture.
