of the kino is a very interesting subject. It would seem that it grows after the 

 attacks of a large grub of the longicorn beetle family, and is probably due to 

 bacterial infection following the exposure by this grub of the tissues that lie just 

 under the cambium layer of the tree. 



If it is possible to prevent the inroads of the insect pest, then it is certain 

 that marri timber will become an exceedingly valuable product of the forests. On 

 the other hand, should this prove impossible, we have in the kino a valuable tanning 

 material which may prove of greater worth than the timber.
