The Centennial Building

The Philadelphia Press says that the " area of ground appropriated at Fnirmount Park f or the Centeuuial Exposition is 450 acres, and is bounded by the Sohuylkill river on the eatt, Girard avenue on the southeast, Elm avenue on the south, and Fifty-seeond street o.n the west - so that Girard avenue, when graded and paved, as is conteroplated, will be the inain approach to the buildings. Elm avenue and Fortieth and Forty-first streets will also lead to the park, and steps have been taken by Councils looking to the iinprovement of these thoroughfares, in order that they may be made available before the opening of the Exposition. The ground plans, as approved by the Coinmission, provide for the erection ot a machinery hall, agncnltural hall, conservator}', art gallery, and themainExpositiou building. AUJof thess will be so located as to be with'in easy reach of each other, and upon the most baautiful portion of the park. The grand pavilion, or main Exposition building, will have a frontage of 2,075 feet on Elin avenue, or, in other words, will extend froui Forty-first strt-et un the north, and near the Lansdowne drive, it is designed to erect the art gallery. West of the Exposition building will be the machinery and agricultural halls - the former to" be 2,275 feet long, and the latter 1,420 feet. These are to be connected with the main buildings by a cóvered passage-way, and will also bw upon Ehn avenue. A better idea of tha immensity of the work to be performed, and of the ground to be occupied, will be had whpn it is stated that the grand pavilion will cover an area of 36.5 acres, which can be increased to 44 acres. Machinery hall will occupy 9.5 acres, and agricultural hall 4.5 acres."
