=Mr. Garnsey’s Ceiling Painting.=--The disc of the dome contains one of the most interesting and ingeniously arranged of the purely conventional decorations which ornament the Library. In the centre is the great seal of the United States, which puts the final touch of significance upon the series of paintings in the tympanums. Surrounding it is a circular band containing forty-eight stars, one for each State and Territory. On the diagonal axes of the room are four medallions containing heads symbolizing the Four Winds--North, South, East and West--each blowing a gale from his mouth, as in the classical representations. They stand, of course, for the four great natural divisions of the country. Below each medallion is a garland of fruits or grains, festooned from bunches of eagles’ feathers which spring from the central panel of the decoration, and indicating the nature of the products of each section. The garland under the medallion of the North Wind, for example, is composed of apples, pears, peaches, and similar fruits; that under the East Wind, of various vegetables and berries; under the West Wind, grains, as wheat, oats, and maize; and under the South Wind, bananas, pomegranates, oranges, lemons, and so forth. Other emblematic objects introduced into the decoration are lyres, each flanked on either side by a horn of plenty filled with fruits; and flaming torches, set between a pair of dolphins. There are thus two sorts of groups, each of which occurs four times in the decoration in accordance with the standard fixed by the four medallions of the Winds. The four different objects depicted signify four of the great interests of the country--the lyre, the Fine Arts; the cornucopia, Agriculture; the torch, Learning and Education; and the dolphin, Maritime Commerce. Finally the composition is united by American flags festooned from the lyres to the garlands of fruit which underhang the medallions of the Winds. And around the whole is a narrow border, on which are inscribed the following words from Lincoln’s Gettysburg address, used also, in part, by Mr. Vedder in his decorations in the Entrance Hall:-- That this nation, under God, shall have a new birth of freedom; that government of the people, by the people, for the people, shall not perish from the earth. THE PAVILION OF ART AND SCIENCE. The entablature and paired pilasters which decorate the walls of the two pavilions to the south, are resumed in the Northwest Pavilion, or Pavilion of Art and Science, if one choose to name it, as the three corresponding rooms on this floor were named, from the subject of the paintings which it contains.
