the cool season pleasant. The annual rainfall on the Arracan Yomahs 
may reach ioo inches, at Sidoktaya in the Mon valley it varies from 
45 to 70 inches, at Minbu town from 20 to 40 inches, and at Salin 
from 14 to 40 inches. During the hot season the Salin river practically 
dries up, and only a little water remains in the Man river. The Mon 
river, as already mentioned, remains navigable to country boats as 
far up as Sidoktaya. 
CHAPTER III — SKETCH OF THE VEGETATION. 
The following is more an attempt to record the writer’s impres- 
sions of what was at best but a hasty rush across the district, than 
an endeavour to give a complete sketch of the vegetation thereof, 
which would require a much longer stay,— extending over the three 
seasons — than the writer was able to afford. 
At the time of our tour the hot season had set well in, and the 
conditions normal to it were prevailing, and it is more properly the 
aspect of the vegetation during that period that is described below. 
It is cause for regret that our excursion to the Arracan Yomahs 
was so short, but official duties compelled our return to Minbu before 
the close of the Government financial year on the last day of March. 
This vexing lack of time explains to some extent the sadly deficient 
account of the Yomah vegetation. 
The Nwamadaung range where we traversed it is covered with 
fairly open deciduous forest, which the writer, if following Kurz’s 
classification set forth in his i( Preliminary Report on the Forests 
and Vegetation generally of Pegu f would .describe as an upper 
mixed forest. At the time of our visit almost all the trees were 
leafless, and there was in consequence a total absence of shade 
against the burning rays of an almost vertical sun, which rendered 
our march across the range distinctly fatiguing. The trees compos- 
ing the forest are of medium height and of many different species. 
Amongst the more common and conspicuous are Shorea siamensis — 
Ingen or Ingyn of the Burmese — , a species of Bombax with a fruit 
of large diameter which Kurz appears to have considered — errone- 
ously as it seems to the writer — Bombax insignis ) Millettia pendula ) 
M . Brandisiana ) Dalbergia cultrata , D. paniculata. , Pterocarpus 
macrocarpus , Cassia renigera ) Cassia timoriensis ) Bauhinia poly- 
carp a, B . variegata ) Xylia dolabriformis , Terminalia tomentosa , 
Anogeissus acuminata var. lanceolata , Lagerstrcemia tomentosa , 
Gardenia erythroclada—voxy noticeable with its peculiar cinnamon 
brown bark, — many Bignoniacex , such as Oroxylum indicum , 
Dolichandrone stipulata y D . Rheedii , Heterophragma sulfureum y
