152 CINCHONA — GOLD. 



the former, tlie tree, after luiviii^- reached maturity, 

 yields at once the maxinnun of bark, at least, one- 

 third more than obtainable by coppicing ; 1 )iit the trees 

 are sacrificed, and the soil having- to lay fallow for 

 several years, one crop is obtainable within not less 

 than ten years, whilst by the other mode (the coppic- 

 ing) the trees will grow another crop in four, five, or 

 six years. The C. Calisaya (yellow bark, yielding- 

 larger proportion of Cinchona than the C. Succirubra, 

 producing red bark), by uprooting, will give from half 

 to two or even three pounds of bark per ton, accord- 

 ing to age. Another species, which has also been 

 grown with good results, is the C. Ledgeriana ; its 

 discoverer is Mr. Ledger of Tucuman, the central 

 province of the Argentine Republic, — the Eden of 

 America, according to native writers. In Sikkim, 

 Northern India, there is a large government Cinchona 

 factory, which will in due time be able to supply the 

 entire quantity of sulphate of Quinine needed by the 

 u'overnment of India. 



Gold has also of late years been discovered in 

 Mysore, notably in the Kolar district, where several 

 mines are now being worked, returning large profits 

 to the fortunate shareholders of some of the numerous 

 companies started.
