Divi-Divi is the commercial name for the curved pod of a 

 leguminous shrub, Ccesalpinia coriaria, which is sometimes im- 

 ported from Carthage. Its tannin differs materially from that 

 of nutgalls. ; t,The quantity of mucilage which it contains pre- 

 cludes it from the use of dyers ; but, as it furnishes nearly 50 

 per cent, of tannin, it is largely used by curriers. It is imported 

 into Liverpool from Rio de la Hacha, Maracaibo, and Savanila. 400 

 tons of the seed pods and bark of the Algaroba, or Locust-tree 

 (Prosojjis pallida), were imported in 1849 into Liverpool from 

 Valparaiso, as a substitute for divi-divi in tanning. 3,200 lbs. 

 of divi-divi were exported from the port of Augostara, in 1846. 



Specimens of divi-divi which had been raised at Calcutta were 

 shown in the Indian department of the Grreat Exhibition, 



Dr. Hamilton states that, according to some admirably con- 

 ducted experiments of Mr. Eootsey, of Bristol, undertaken at 

 his request, the pods of divi-divi contain above 50 per cent, of 

 tannin. It appears also, from trials made, that one part of divi- 

 divi is sufficient for tanning as much leather as four parts of bark, 

 and the process occupies but one-third of the time. 



The average produce of pods from a full-grown tree has been 

 estimated at 100 lbs. weight, one-fourth of which consists of 

 seeds or refuse, leaving about 75 lbs. of marketable matter. 



At an interval of six feet apart, an acre of ground will contain 

 1,210 trees, yielding an average of 810 cwts., and 30 pounds, 

 or above 40| tons of marketable matter, worth, at only 

 £5 per ton, £200. Should the interval between the trees be
