be done after the wound is fairly well 

 healed up. Before taking them out of 

 the ground prune off about one-third 

 of the foliage. Great care should be 

 exercised to prevent the roots from dry- 

 ing out or from being bruised. In 

 " boxing " the plants, carefully work 



the soil in among the roots and allow 

 them to remain in as natural a position 

 as possible. Water the plants thorough- 

 ly and keep them well shaded for a few 

 days. When they have thoroughly es- 

 tablished themselves they are ready for 

 transplanting to the field.

Pour Botanic Gardens in the tropics 

 are noted for their wealth in plants, the 

 beauty of their arrangement, and the 

 magnificence of their situation ; these 

 are the gardens of Rio Janeiro, Brazil ; 

 Peradeniya, Ceylon ; Singapore in the 

 Malacca promontory , and Buitenzorg, 

 Java. 



Of these the richest is undoubtedly 

 the Botanic Garden of Buitenzorg ; it 

 also has the largest number of labor- 

 atories and experiment stations, and is 

 an ideal place for students of botany and 

 agriculture, 



Moreover, Buitenzorg extends to for- 

 eign students more generous and ready 

 welcome than any other similar in- 

 stitution ; a special laboratory is reserved 

 for their use, and the library with its 

 rich collection of botanical and zoological 

 collections is open to them. Buitenzorg 

 is especially interesting for the study of 

 tropical agriculture, as this place is the 

 headquarters of the technical branches 

 of the Department of Agriculture of the 

 Dutch East Indies. 



Buitenzorg, called the Eden of the 

 tropics, comprises the European town, the 

 Governor-General's residence, partially 

 surrounded by the Botanic Garden, the 



native city,and the Chinese Kampong. It 

 is enclosed by two torrential rivers, the 

 Tjiliwong and the Tjisadane. Buitenzorg 

 enjoys a mild climate, due not to its 

 altitude, which does not exceed 265 

 meters, but to frequent storms and daily 

 rains. The average temperature for 

 the year is 20° C. The average for 

 September, the hottest month, is 25 '5° O, 

 and that for February, the coldest 

 mouth, never falls below 14"5° C, During 

 the day the thermometer registers 

 30°, 31° and even 33° C. during the hot 

 season. The climate is very damp. It 

 rains almost every day, generally 

 between 12 and 4 p.m., and the rain is 

 often accompanied by violent storms, 

 sometimes by almost uninteirupted 

 electric discharges- The total annual 

 rainfall at Buitenzorg is 4,367 mm, or 

 double that of the dampest regions of 

 the Belgium Congo. The rainfall is very 

 evenly distributed, as it rains one day on 

 three even in the driest season. 



The average rainfall at Buitenzorg is :— 

 January ... 471 mm. 25 days of rain

The first agricultural institution 

 opened at Buitenzorg was an Experi- 

 mental Garden, to which a botanical 

 collection was annexed from the start.
