The attack was got under in a couple of months by handpicking. 
It is Oryctes rhinoceros which makes the tunnels into palms that Rhyn- 
chophorus ferrugineus uses for egg-laying; and it seems probable that the 
same happens with Protocerus colossus. Several years ago Mr. Ridley 
recorded that the Rhinoceros beetle can mature in rich humus; in the course 
suppressing the attacks described, an instance of this was found. 
Mr. Ridley upon another occasion remarked that palms in the Gardens 
died slowly some short time after an unusual spell of dry weather; is it 
not possible that the dying then was due also to an outbreak of Protocerus 
colossus ? 
Orchid beetles were troublesome. A caterpillar probably of the genus 
Zeuzera was extracted from the branches of a wild Litsca and from the 
branches of the Avocado pear. Papilio polytes did some damage to Citrus 
trees in February. 
The Gardens’ only plant of Warczewiczia suffers considerably from the 
attack of an insect which damages the foliage; it was observed that while 
the lake was half empty the attack abated.

A vote of $700 had been taken for a slight cleaning away of silt at the 
the upper end of the lake when the Anti-mosquito Committee, as a preliminary 
to work which they wished done on the ponds in the adjoining Tyersal grounds, 
approached the Gardens Committee on the subject of the lakes and ponds 
in the Gardens. The result was an undertaking on the part of the Gardens 
Committee to fill the Nelumbium and Limnanthemum ponds at the foot of 
the lake with the silt to be got from the Gardens’ Lake, and a recommenda- 
tion that the Cluny Lake should be filled also. With a reduction in coolies’ 
wages in sight, the Gardens Committee saw the possibility of accomplishing 
the filling of the ponds by means of savings on the Gardens’ labour bill, and 
that at the same time a much more effective deepening of the lake could be 
brought about than the small vote of $700 promised. Meanwhile the Munici- 
pality was able to come to an agreement with the State of Johore, as landlord 
or Tyersal, for the draining of the Tyersal ponds ; and as it was desirable to 
await operations there before beginning in the Gardens, and also to get wages 
down, a commencement w'as postponed until June 1st : but from that date 
to the end of the year the Gardens lake was kept only half filled, while
