titles on the fertile groiiiid, periodically very moist and black, at 

 the foot of the Watangan range, whereas higher up on the rocky 

 slopes of this tertiary hill, teakwood is of much better quality'). 



C. G. VON Dkntzch, on the other hand reported that most of the 

 trees cut in the residence of Rembang (where limestone and marl 

 predominate) belong to djati-kapur ') ; this at least was the case with 

 the trees used in the "Artillerie-construktiewinkel" of Surabaya. On 

 the basis of the fact that this variety is found on the white lime- 

 marl-formation at Sui-abaya and ilembang, F. Junghuhn asserted 

 positively that it originated from the nature of the soil'j. in his 

 account P. F. H. Fromberg had in mind the phosphoric acid content 

 of the soil rather than the lime. According to him this content must 

 be comparatively high in places where the teak-tree grew *). G. Thoms 

 went even so far as to think that under the teak forests phosphorite- 

 beds were to be found, which has not been proved^). 



According to J. W. H. Cordks leak forests thrive best "where 

 the soil is rich in various lime-compounds, but he admits that also 

 volcanic grounds produce good teak trees"). H. J. Kerbkrt never 

 met with such a luxuriant growth of the teak as in Japara . . . on 

 light volcanic grounds that differ in nature entirely from the typical 

 teak-forest grounds'). 



Statistic data with reference to the number of the hewn trunks 

 of cljati-ka/mr enabling us to compai'e them with other varieties, 

 are missing altogether. Certain it is, anyhow, that the majority do 

 not belong to the first mentioned variety. According to P. van 

 Rkes it is found and used most after the djati swiijo is perhaps
