occur in kampongs anywhere, but during that month it was found 
fairly commonly on kampongs in the Raub district of Pahang by the 
Assistant Agricultural Inspector, Selangor, and the author. The 
treatment of this disease in the kampongs will be a difficult matter 
and can only be carried out by a trained gang or gangs of coolies 
specially employed by the Department. Both the identification of 
the disease and its treatment require more or less expert knowledge 
and the Malay subordinate officers will have to be most carefully 
trained before such work can safely be left to them. 
Steps must, however, be taken early to decide the distribution of 
the disease in the kampongs and measures must be devised for its 
treatment. 
Locust Work. 
In Selangor and the Negri Sembilan the Assistant Agricultural 
Inspectors have been responsible for supervising the work of des- 
troying locusts, for which purpose a special stall was provided. The 
work commenced in September, 1913, and continued in Selangor 
until the end of 1915. A few locusts were present during 1916 and 
a small staff was kept until the end of the year to watch them. 
No eggs were, however, laid and the State is now practically free 
from locusts ; unless there is still a small swarm rapidly dying out 
at Sepang ; none are known to occur elsewhere. In the Negri 
Sembilan work went on continually during the years 1913, 1914, and 
1915 ; the staff was reduced in 1916 as the number of locusts became 
less and only part of the subordinate staff was left under the direct 
control of the Assistant Agricultural Inspector. Naturally the 
locust work occupied much of his time in 1916. At present there 
are no more locusts in the Negri Sembilan and very little more work 
is expected there. 
The Chief Agricultural Inspector has been in chief control of 
this work throughout; besides general supervision of this work in 
Selangor and the Negri Sembilan since August, 1913, he has also 
had to supervise work on locust destruction in Jokore since October, 
1914, and in Malacca since March, 1916, In both these States the 
number of locusts is now much reduced. 
Work on Estates. 
The work of European inspecting officers on estates has been 
almost entirely of an advisory nature. In two or three cases letters 
requiring the treatment in accordance with the Enactment of one or 
two diseases, usually pink disease, have been sent out, but in no 
instance has a court case been necessary to enforce the measures 
required. 
As part of the routine work the distribution of pink disease by 
mukims has been determined and practically every infected estate 
is known in Perak, Selangor and the Negri Sembilan, in Pahang the
