owing to the smaller working qualities of teakwood as timber ^). 



It must be admitted, thei-efore, that djati kapur is not i-estrioted 

 to lime- and marl-grounds, also that not all trees growing on those 

 grounds belong to this variety'). Other influences must be exerted 

 here. To answer this question it is first of all necessary to ascertain 

 whether djati kd/m.r may be called a vai-iety by itself or whether 

 we have to do here oidy with an aberration, foiniing under certain 

 circumstances only. According to Koordkks and \ M. v/roN djati kapur 

 can only be recognized in the wood and not in the stem, like other 

 varieties of Tectona^j. 



However, F. van Rkks already reported : "The outward marks of 

 identity are according to the Javanese, the smaller, thinnei- yellowish 

 leaves and the finer bark"'), but he added: "tliesemaiks, however 

 are deceptive, the true characteristics being found inside"'). W. L, 

 Sturi.kr does not distingnish dj'iti kapur from othei' varieties 

 only by the bark, the nature of the wood, the shape and the 

 colour of the leaves. H. J. Sp.\an also says that some wood- 

 cutters can tell from the outside of a tree that it is djati kapur 

 namely from "the bark, the stem and the leaves""), What P. van Rkks 

 writes further about the fruits is also worth noticing: "In the exceed- 

 ingly small fruits of this sort fine limeveins are said to have been 

 detected" "). 



Whether this is really the case, has nevei- been examined, nor 

 have any efforts ever been made to ascertain by sowing-experiments 

 whether or no from these frnits repi-esentatives of djati kapur may

2) M. BiiSGRN also thinks that the commercial reputation of Java-teak is based 

 on wood from cljatikapur (Die Eigenscliatien und Production des Java-Teak oder 

 Djali. Beiheft zum Tropen pflanzer 8. N". 5. Berlin 1907, p. ;-!69). P. Geesink 

 also says that in 1905 and 1906 much wood was exported from Java, totally 

 unfit for foreign markets (Staatsexploitatie van Djatibosschen op Java — Tijdschr. 

 voor Nijv. en Landb. in Ned.-lndië 75. Batavia 1907, p. 133). 



3) To solve the question of the widely differing amount of magnesiumoxide a 

 larger number of ash-analyses of Djatikapur as well as of soilsamples from the 

 places where they are taken from, seems to be required.
