THE BOTANISTS OF PHILADELPHIA. 17 



The University Botanic Garden was begun with the 

 erection of the building for the School of Biology. It con- 

 sisted, in 1SSS, of about a quarter of an acre of ground 

 immediately surrounding the Biological School, planted 

 with a few systematic and experimental beds. The planted 

 grounds were surrounded by high gravel banks, overgrown 

 with weeds. It was not until 1890, when a large part of 

 this glacial gravel deposit had been sold and carted away, 

 that the botanic garden may be said to have had its

 house plants was also a feature of the garden at this time.

 an acre of ground surrounding the laboratory building. 

 Several rare shrubs were set out, among them, Neviusia 

 Alabamensis, an anomalous rosaceous plant found growing 

 wild in the Southern states. The grass plots, shrubbery and 

 systematic beds then occupied a terraced depression front- 

 ing 011 Pine Street. 



The development of this garden, however, took place

 University. In 1893, immediately after his appointment to 

 be Professor of Botany, Dr. John M. Macfarlane submitted 

 plans for the establishment of the botanical garden, on the 

 triangular piece of land back of the biological laboratory. 

 Various circumstances conspired to prevent the carrying
