12 STUART : THE' SRIMANGAL EARTHQUAKE OF 8TH JULY 1918. 
from east to west.^ The railway line at this point is running approxi- 
mately east and west and Rasidpur lies west 6° north of Kalighat. 
After the earthquake it was found that the east and west gable ends 
of the leaf-house and factory had fallen, while the longitudinal 
east and west walls had all diagonal cracks. 
There are three trolley systems running through the epicentral 
area, one running from Srimangal to Tiprachara, with a branch 
line to Rajghat and Udnachara ; another from Satgaon to Hugli- 
chara ; and the third from Rasidpur to Daragaon. All three systems 
lun north and south, and on each system the line had bulged in 
])laces towards the east. This is of special interest since the trolley 
line in the Doloi valley, situated along the edge of and just outside 
the opposite side of the epicentral area, was found to have bulged 
towards the west. Other than the tea estates the only place of any 
importance situated within the epicentral area is Srimangal. Here 
many houses were thrown down in the bazaar and the station 
buildings damaged and partially thrown down. The direction of 
fall in this case was north and south. 
Along the portion of the railway line that is situated within the 
epicentral area, the damage done does not seem to have been 
excessive. Between Srimangal and Satgaon, although the bridges 
and the line showed evidence of having been badly shaken, 
the alignment does not seem to have been very much upset. The 
Udna, Billash, and the Kalighat bridges show no side or end move- 
ment to speak of, but in both the Udna and Billash bridges the 
abutments sank and closed in. 
In the pass through the Balisera hills, between Patrakhala and 
Kalighat landslips of considerable size were reported by the garden 
coolies.
