the Tu and Duya in Henzada, the Shahkegyi
and the Inyegyi in Bassein, the sacred lake at Ye in Tenasserim, and the
Nagamauk, Panzemyaung and Walonbyan in Arakan. The Meiktila lake covers an
area of some 5 sq. m., but it is to some extent at least an artificial
reservoir. In the heart of the delta numerous large lakes or marshes
abounding in fish are formed by the overflow of the Irrawaddy river during
the rainy season, but these either assume very diminutive proportions or
disappear altogether in the dry season.

_Climate._--The climate of the delta is cooler and more temperate than in
Upper Burma, and this is shown in the fairer complexion and stouter
physique of the people of the lower province as compared with the
inhabitants of the drier and hotter upper districts as far as Bhamo, where
there is a great infusion of other types of the Tibeto-Burman family. North
of the apex of the delta and the boundary between the deltaic and inland
tracts, the rainfall gradually lessens as far as Minbu, where what was
formerly called the rainless zone commences and extends as far as Katha.
The rainfall in the coast districts varies from about 200 in. in the Arakan
and Tenasserim divisions to an average of 90 in Rangoon and the adjoining
portion of the Irrawaddy delta. In the extreme north of Upper Burma the
rainfall is rather less than in the country adjoining Rangoon, and in the
dry zone the annual average falls as low as 20 and 30 in.

The temperature varies almost as much as the rainfall. It is highest in the
central zone, the mean of the maximum readings in such districts as Magwe,
Myingyan, Kyaukse, Mandalay and Shwebo in the month of May being close on
100 deg. F., while in the littoral and sub-montane districts it is nearly ten
degrees less. The mean of the minimum readings in December in the central
zone districts is a few degrees under 60 deg. F. and in the littoral districts
a few degrees over that figure. In the hilly district of Mogok (Ruby Mines)
the December mean minimum is 36.8 deg. and the mean maximum 79 deg.. The climate of
the Chin and Kachin hills and also of the Shan States is temperate. In the
shade and off the ground the thermometer rarely rises above 80 deg. F. or falls
below 25 deg. F. In the hot season and in the sun as much as 150 deg. F. is
registered, and on the grass in the cold weather ten degrees of frost are
not uncommon. Snow is seldom seen either in the Chin or Shan hills, but
there are snow-clad
