IV. THE BOTANICAL INSTITUTE ('S LANDS PLAN- 

 TENTUIN) AT BUITENZORG. 



Several extensive publications describing this admirable institution 

 have recently appeared, and it is accordingly not my object to go into 

 detail regarding it in the present paper, but only to record some of the 

 methods of investigation and call attention to the equipment of the 's 

 Lands Plantentuin. 



The botanical garden at Buitenzorg forms a great park surrounding 

 the residence of the governor-general of the Dutch East Indies. It was 

 established in 1817 by Eeinwardt, who was afterwards a professor at 

 Leiden University. Following Eeinwardt, Dr. C. L. Blume, as the first 

 regularly appointed director, had charge of the gardens. In 1830 James 

 Hooper, who came from the Royal Gardens at Kew, England, returned 

 to Europe, and Mr. J. E. Teysmann was appointed his successor. To 

 him are largely due the present beauty and utility of the botanical gar- 

 den. It was Teysmann who, at Hasskarl's suggestion, adopted the 

 plan of arrangement after the natural order of plants, so that, owing 

 to this most convenient arrangement, it is now comparatively easy for one 

 to study and compare the species of any one natural order, although there 

 are now in cultivation over 10,000 species, covering an area of 147 acres. 



When Teysmann resigned in 1859 Binnendyk was appointed to suc- 

 ceed him, and in the meantime the whole institution was reorganized on 

 a plan drawn up long before by Teysmann. 



In 1868 Dr. Scheffer, a man well qualified for the position, was ap- 

 pointed director. In 1875 he established the publication of the "An- 

 nales du Jardin Botanique de Buitenzorg." Above all other things in 

 value, however, is the experimental garden established by Scheffer in 

 1876 — a garden of 180 acres for experimenting on a large scale with eco- 

 nomic species. Dr. Scheffer died in 1880, and Dr. Treub, the present di- 

 rector, was appointed his successor. 



The present magnificent equipment and wide influence of the 's Lands 

 Plantentuin is due largely to the well-directed efforts of Dr. Treub, a gen- 

 tleman who is by education and inclination most admirably fitted for di- 

 recting such an institution. At the time of his appointment in 1880 the 

 institution practically corresponded to what is now the fifth division ; for 

 at that date that most practical adjunct, the experimental garden, had 

 been established but four years. Since the year 1880 the institution has
