up one of the forks and then came down the main 
stem, its total length being from 15 to 16 inches. One- 
air-hole present. This gallery ended near where No. 4 
commenced. 
6th—New Gallery.—A tunnel containing a living larva. 
which ran down one of the forks and ended very 
near where No, 5 joined the main stem. The grub 
inside was not more than 4-8rds grown, and the 
gallery appeared to be still in course of construction. 
It was apparently on its way to the main stem. 
From the above we see that there were no less than five 
tunnels in the main stem (two of which contained living grubs) 
and one unfinished one in a fork of the crown near where it 
joined the bole. The tree was alive but badly stag-headed. 
It was growing near Osahatti, in the sandal-wood coupe No. 7. 
Results of Attack.—Only living trees are attacked by this 
pest, and it would appear to confine itself to saplings and: 
young poles. The sandal is not necessarily killed by the action 
of the boring grubs; in fact, unless these latter are numerous 
the tree is probably but little inconvenienced and the cambium 
layer soon covers over the old air and exit-holes made by 
the pest. In such cases there is no evidence externally that. 
the tree has been attacked. When it is felled and converted,, 
however, the heart-wood is found to contain the old galleries, 
made by the boring grubs which infested the tree when young, 
and the value of the wood is thereby greatly lessened, no matter 
how fine in quality it may be, At other times, however, the: 
tree shows externally plenty of evidence of old attacks. The 
air-holes and exit-holes are plainly visible, and if the sandal is. 
from any cause sickly and unable to cover these over they begin, 
under the action of the sun and rain, to ‘‘ weather,” become greatly 
enlarged and even at times coalesce. When the latter takes 
place the tree will be found to have its centre exposed on one- 
side, perhaps for a distance of several fect, and a considerable 
amount of “heart” wood will have rotted away under the 
‘ weathering” action, 
The plantation at Bailur was visited and inspected. The 
poor character of the growth here was due to other causes, but.
