Klang. The town of Klang, situated on the river of that name, is 
Dunded on the north by the river, on the west and south by a range of 
nail hills, clad for the most part with jungle, and on the east by hat land 
(tending down to the river. The river is tidal and the greater part ot the 
)W n is but little above the level of its banks. The hills are spurs running 
at from the end of a long range which stretches away m a southerly 
irection for about 5 miles along the Langat Road when the land again 
ecomes flat and swampy. More westerly the land is flat right away to the 
aast. At the foot of the hills, as the map shews, the ground water is high 
nd the land here is permanently swampy. The ground on either side ot 
le railwav is always more or less swampy, and in places the water lying 
ere is covered with floating weed. The hills, except where they have been 
leared, are covered with ordinary jungle. The land in the open spaces of 
ie town has all been cleared, but in places it is now covered with low 
ndergrowth, which Dr. Watson tells me is of about a years growth. 
Nature of the soil varies considerably. Near the river on the lower 
inds it consists of a covering of organic detritus lying on a bed of clay. 
) n the hills the upper soil is red earth and in the jungle this is. coveted 
v ith decaying vegetable detritus. On the sides of the hill there is a vein 
if red sand. Doubtless the clay substratum tends to maintain the g r c> und 
n a swampy condition. During the time spent at Klang rain fell at 
ntervals of 3 days for about 3 successive days at a time. The average 
lailv rainfall was less than half an inch spread over about 8 days, the 
leaviest daily fall being 2.89 inches, the lightest *oi. Most of the ram tell
