BALL AND SIMPSON: COALFIELDS OF INDIA. 
(4) Sah-tvng-gah (Satunga ?), 3,500 feet ; 
(5) Shei-inaiig, 4,000 feet. 
The additional localities discovered since this list was drawn up 
are : — 
Khasia Hills. — Langrin, Nongbredeni, Uni-rileng ; 
Jainlia Hills. — Borsora, Wapung and Lenkensmit, Jarain, whilst 
many of these fields have been examined and described by various 
officers of the Geological Survey. 
Mao-beh-larkar. — This tiny field of Cretaceous coal has an area of 
about 11 acres only. It is situated near the Bog(^pani river, about 
19 miles south of Shillong; the workable coal seam has an average 
thickness of about 3 feet. The coal is compact, splinterv, has a 
smooth conchoidal fracture and a woody sound when struck. It 
contains numerous specks and small nests of fossil resin, and a 
considerable quantity of sulphur as iron pyrites. LaTouche ^ has 
stated that at a moderate estimate the field contains oome 52,000 
tons of coal. For many years the coal of this field was worked 
for supplying the station of Shillong. 
Mallet ^ has described the occurrence of coal near Moflong, 
about 5 miles north of Maobehlarkar. In two localities, near 
Umsaomat, the seams are only one foot thick and are shaly. On 
Dedum hill, however, a seam, three feet thick, occurs and appears 
to be workable. 
The following analysis of the Maobehlarkar and Dedum coals 
have been published ^ : —

Cherrapunji and Maolony. — In this neighbourhood coal of Tertiary 
age occurs in several localities, usually on a horizon some 10 to 
15 feet above the nunmiulitic limestone. The thickness of the 
seam is extremely variable but near Cherrapunii an area of about | 
square mile has been considered to be workable. In this area the 
coal is from 3 to 7 feet in thickness and lies almost horizontally,
