In one particular instance where the plants were badly 
affected, I attributed the attack to the fact that the young 
seedlings had suffered from an insufficiency of water at the 
roots. 1 he nurseries had been made under the shade of large 
trees, and the seedlings had suffered owing to the fact that during 
a comparatively dry spell of weather, the soil, being full of the 
roots of the older trees, had become too dry -to support a large 
number of seedlings growing close together in nursery beds. 
Moreover the beneficial effect of heavy showers in cleansing the 
foliage, such as we are accustomed to in a dr} r season, is lost to 
the plants when growing under shade. 
This disease is chiefly limited to plants growing under 
unfavourable conditions, and is not likely to affect trees when 
once established. I am of opinion that it may be entirely 
avoided by making the nursery beds in a damp locality in such 
a position that the seedlings will derive the full benefit of a free 
circulation of air and be subjected to the full effect of heavy 
showers from time to time. The soil should be free and well 
drained, but capable of retaining plenty of moisture even in 
comparatively dry weather: if necessary, artificial irrigation must 
be resorted to, but care must be exercised that this is done 
thoroughly as opposed to frequently, an operation which would 
be worse than useless in the case of small seedlings exposed to 
the full blaze of a tropical sun.

THE AGRICULTURAL SHOW AT 
KWALA LUMPUR, 1904. 
The Report on this Show, held in Kwala Lumpur, 5th, 6th 
and 7th August, has just been published. As it is rather too long 
to publish completely in the “Bulletin" we extract from it such 
facts as are interesting specially to the general public. It was 
agreed on all hands that the Show was a success, and the 
President, Mr. D. G. Campbell, attributes this to the members 
of the various Committees and District Officers who laboured so 
energetically for this end'. “It cannot,” he says, “be said that 
“ the Show was held as the outcome of any special interest on the 
“ part of the general public or even of the planting community, 
“ on the contrary it was held at the instigation of the Govern- 
“ ment.” And it must be admitted it is true that a certain
