twice, and afterwards perishes. If, however, it is placed in a 

 fertile soil, it grows into a perfect tree. This mode of pro- 

 pagation is a common and profitable custom among the 

 Chinese inhabitants of Batavia. They hire for themselves 

 certain gardens, or lease a piece of land for a series of years. 

 They practise this art with the object of obtaining fruit 

 immediately. Others, in order that old trees may become 

 productive, cut off many of their branches, and transfix the 

 trunk with a strong nail. This can also be done, and is 

 equally effective with the trees called Nanca, and Bonga 

 Tanjong" 



Observation. 



This appears to be the same species, or at all events, 

 variety, which is called Aur. Stellatum, and roseum by Ferrar 

 in Hesper., 395. (Vide pi. 59, figs, c, d, e, of Atlas.) 



(Nota bene. This Aur. verrucosum appears to have all the 

 characters of the Portugal or Malta orange, but it is a warty 

 variety. It was not, however, common in the Malay archi- 

 pelago in the time of Rumphius, some 200 years ago. It 

 appears to have been then of recent introduction in those 

 islands. Rumphius thought it was brought by the Chinese, 

 and speaks of it in connection with the Chinese inhabitants, 

 the natives not having at that time taken to it. Europeans 

 however, frequently planted it in their gardens. On the 

 back of Tab. 35 of Rumphius, Buchanan Hamilton wrote 

 " Chdndpur orange" What the latter is I don't know.)

The following layering-clay is successfully used by Girdharl 

 Chawdree, of the Horticultural Garden, Lucknow. He uses 

 it with advantage for those plants that are difficult to layer. 

 His receipt for making it is the following : 



5 seers, linseed oil-cake (alsi-ki-khali). 



5 seers, Paddy husks (dhan-ki-bhusi). 



5 seers, iirud flour (urud-ka-ata). 



5 seers, fresh cow-dung. 



125 seers, clay (chickni-mitti).
