THE BOTANISTS OF PHILADELPHIA. 429 



appendix v. 



Horticultural Hall, 



Fairmount Park. 



A history of the botanists of Philadelphia would not 

 be complete without an account of the horticultural build- 

 ing erected in Fairmount Park for the Centennial Exposi- 

 tion of 1876. Without doubt, the horticultural, botanical, 

 forestal and floral exhibits at the Philadelphia Centennial 

 Exposition stimulated the scientific interests of the country 

 and also the horticultural, lumber and florist industries 

 established in the United States. The horticultural build- 

 ing erected then, still stands, and is, in itself, a great 

 botanical institution, supported by the City of Philadelphia. 

 A sketch of the structure, written for the " Historical 

 Register of the Centennial Exposition,* will give a better 

 idea of its arrangement and size. 



" It is located on the Lansdowne Terrace, a short 

 distance north of the Art Gallery, and has, like the latter, a 

 commanding view of the Schuylkill River, and a portion of 

 the city. The design is in the Mauresque style of archi- 

 tecture of the twelfth century, the principal materials, 

 externally, being iron and glass. The length is 383 feet, 

 the width, 193 feet, and the height to the top of the lantern 

 seventy-two feet.f 



" The main floor is occupied by the central conservatory, 

 230 x 80 feet, and fifty-five feet high, surmounted by the 

 lantern, 170 feet long, twenty feet wide, and fourteen feet

fA number of years ago this lantern was removed, and the entire roof 

 arched over with glass lights for the better growth of the plants.
