The New Jersey Building, Hugh Roberts, of Jersey City, architect, like those of Pennsylvania and Virginia, tells of the days of the Revolution. It is a copy of the old Trenton barracks, erected in 1758, and used alternately by British and Colonial troops during the Revolution. Within, its simple and comfortable appointments make it one of the most popular of the state buildings. A large lounge with blazing fireplaces, and furnished in white reed, occupies the entire central section. In the east wing are the offices and rooms of the Commission. The west wing contains the lobby and a reception room in which hang two large marines painted by N. Hagerup, of San Francisco. As the building is to be President Wilson's headquarters if he comes to the Exposition, a splendid suite, corresponding with the rooms occupied by General Washington, has been furnished and reserved for him. The Maryland Building, designed by Thomas, Parker and Rice, of Baltimore, presents a fascinating study of colonial architecture in its reproduction of "Homewood," built by Charles Carroll of Carrollton in 1802. The present aspect of "Homewood" has been imitated in appearance of age given to the brickwork and the timbering. The contents of the building are no less delightful, historically, than the structure itself. The Colonial Dames of America have enriched the walls with original portraits of colonial celebrities, old prints, original grants by the Baltimores, and many historical documents and relics. Colonial furniture adorns the rooms. Few of the state buildings will so well repay a visit. The Virginia Building, Charles K. Bryant, of Richmond, architect, is as significant historically as any on the grounds. It is a complete reproduction of George Washington's home at Mount Vernon, down to the spinning room, the detached kitchen and the servants' quarters, and furnished in part with Washington's own furniture loaned by Miss Nannie Randolph Heth, of Virginia, the official hostess of the building. There is Washington's chair, Mrs. Washington's work box, Nellie Custis' music stand, and many other relics of the Father of his Country. The remaining furniture, also loaned by Miss Heth, consists of antique specimens brought over from England in colonial days. The West Virginia Building, designed by H. Rus Warne, of Charleston, W. Va., while not copying any individual structure, suggests well-known colonial types. Its veranda, in particular, is like that of the home of the Lees at Arlington. The chief room is the long reception hall, where logs always burn in a huge fireplace, typifying the warmth of West Virginian hospitality. The Mississippi Building, Overstreet and Spencer, of Jackson, architects, was designed to suggest the old-style Southern mansions. Some of its motives, especially the pillared portico, were taken from the old capitol building at Jackson. The displays contained in it are chiefly agricultural. Mississippi is also represented in the Exposition palaces.
