When a log or root containing the termitarium has been 
discovered and destroyed and the ground around it dug 
up it may safely be concluded that the Queen has perished 
with the lest of the individuals. Usually it is only neces- 
sary to trace up the runs in the case of a nest occurring in 
a buried stump or root. 
The first field I systematically cleared of all timber 
five months ago has since shown no sign of the pest. This 
field was planted with Rambong about six years ago it was 
allowed to lapse into bluker and was interplanted with para 
m 1906. The only remaining timber was Kuinpas of which 
there was a considerable quantity. The attack on both 
Para and Rambong trees was particularly virulent in this 
block but has now entirely ceased. 
As Mr. Pratt very truly says owing to the cryptic 
habits ox termites it is very difficult to determine when a 
tiee is attacked until it falls down but during the wet sea- 
sons in October, November, December, and January the 
termites frequently make their appearance above ground 
and this fact I think should be taken advantage of, by mark- 
ing in some way all the trees on which the termites make 
their appearance, for even if they cannot be attended to at 
once, one would at least know where to look for them in the 
future. 
I am afraid that some planters are Lulled into a sense 
of security by the fact that none of their young trees have 
been attacked, it would be well worth their while to make 
a search for T. Gestroi in the timber lying in clearings and 
if found, take steps to eradicate the pest, for although trees 
may not be attacked now, or perhaps for a year or two, to 
come, they will be attacked sooner or later if T. Gestroi is 
present. 
I have not found a single tree attacked so far in my 
forest clearings, but I know that T. Gestroi is present. On 
the other hand in reclaimed land, where owing to the decay 
of most of the timber, T . Gestroi has wandered forth in 
search of fresh fields and pasture new and has made its 
presence evident by attacking young rubber trees. 
On Future Clearings . In these again the importance 
of discovering the forest trees most favoured by T. Gestroi 
is evident. I cannot speak from practical experience, but 
the obvious course to pursue would be to cut down all trees 
known to harbour T. Gestroi and allow them to dry for as 
long a period as possible, prior to the felling of the land. 
Many of these trees would be then destroyed in the burn
