EPICHNTKVI. AND SKYKHF.l.Y SHAKKN AKF.AS. 39 



of the 23rd May and lasted 64 seconds. It was followed by 1 

 lesser shocks during the day, and several well-marked tremors 

 during the night. The general direction seemed to be N. — S. Every 

 masonry building in Taunggyi was more or less damaged. The 

 water level in the supply reservoir fell 1 foot and remained BO 

 for a few hours. During the night it regained the foot, lost and 

 3 inches in addition. The damage done was shown mainly by 

 collapsed or shattered chimney stacks, and cracks in the walls es- 

 pecially over dooi and window openings. The cracks followed the 

 lines of least resistance through the mortar joints. In most eases 

 they were slight and merely showed i 1 1 the plaster, in others they 

 were obvious and the bricks or stones adjoining were loosened. The N. 

 and S. and cross partition walls of buildings were most affected, espe- 

 cially when the length of the building lay N.- -S. In two-storeyed 

 buildings the upper store)- walls were damaged, while the ground 

 floors were practically undamaged. Buildings with walls of brick 

 nogging suffered little, — a panel or two falling out in one or two 

 cases. Chimney stacks of all buildings were cracked and had to be 

 dismantled at once to roof level as a precaution. In the Assist- 

 ant Superintendent of Police's quarters, the lime plaster did not 

 seem to have any grip on the mud walls and fell olf in sheets, while 

 the bricks were shattered. In several buildings the upper courses 

 of walls suffered most, due evidently to the oscillation set up 

 in the roofs. In the Civil Surgeon's quarters the N. bedroom 

 suffered badly while the rest of the house, except for the chimneys, 

 was not hurt. It was noticeable that in some of the smaller brick 

 buildings, e.g., the outhouses of the inspection bungalow, Government 

 clerks' quarters, a followers' barrack in the military police lines, the 

 damage was proportionally greater than in large buildings such as the 

 record room, a stone building 42-|'x39' with walls 22' high, the 

 Government Shan school buildings 224' x55' and 138' x37' with 

 walls 16' and 14' high respectively. In the smaller buildings the 

 walls were shattered or collapsed, while in the others then 1 were only 

 slight cracks or damaged chimney stacks. (PI. No. 5.)
