Well-built erections of brick, usually with tied or jack-arched roofs , 

 have suffered little, whilst some few, such as the Public Works Depart- 

 ment Executive Engineer's office have escaped unscathed. The damage 

 throughout the station and in the bazars, is, however, very serious, and 

 a large number of buildings will require to be re-constructed. 



Details of damage done in Dehra Dun. 



This is a double-story bungalow facing west. Its walls are two - 

 Binfield, No. 24 * eet thick, and in the lower story are of unburnt 

 Rajpur Road. brick, the upper story being a combination of 



boulder and burnt-brick masonry. The building is poorly constructed. 

 The corners of most of the rooms have opened out, often as much as 

 one inch of separation being measurable. The principal damage is to 

 walls running E. — W. The cracks approximate both to the vertical and 

 horizontal but usually follow lines of weakness. The roof is of gal- 

 vanized iron carried on wooden beams. Neither it nor the floors have 

 sustained injury. 



Articles of pottery standing on brackets running E. — W. were 

 thrown down, whilst those on shelves at right angles were unaffected. 



Principal direction of motion probably N. — S.

 St. Thomas' has sustained no serious injury. The worst cracks 



Church, are those which follow the junction of the nave and 



transepts. The transepts were additions to the original building, and 

 consequently their separation can be understood. An old crack in the 

 arch at the N.W. end of the nave has opened out further, but the 

 tower above it is undamaged. Several window arches show slight 

 cracks at the crown, particularly that at the S. E. end of building.
