hill behind is composed entirely of a mass of red granite, and 

 the foundations of the house cannot be many feet, on a bed of 

 clay raised above the granite. My daughter says that she 

 cannot assign any particular duration to the noise and tre- 

 mor, but she thinks it could not have exceeded a few seconds, 

 and the tremor on the second occasion seemed to follow 

 within a second or two what she speaks of as like a peal of 

 thunder." 



Dr Adams of Banchory states, that m his neighbourhood the 

 shock was accompanied "with a sound, — that the shock or con- 

 cussion lasted for 2" or 3", and that the sound continued some- 

 what longer. " The inmates of Banchory Lodge felt as if the 

 floor was raised at one end and depressed at tlie other. All 

 agree, that the concussion and noise came from the westward 

 and passed off by the east. One person who felt the shock 

 distinctly while lying in bed, describes it to me as a tremor or 

 vibration : but all the others felt or fancied that they were 

 rocked or lifted up. There seems no doubt as to the fact, that 

 the shock w as most felt in the upper parts of houses. 



" I have not been able to arrive at any certain conclusion 

 whether the shock was felt more in houses founded on rock 

 than on those built upon sand. It was felt equally strong at 

 Finzean, which is built upon rock, and at Mill of Cliuter in 

 the same locality, which is founded upon sand : at Raemor, 

 w^hich is built upon rock, and at Banchory Lodge, which is 

 founded on sand. The general structure of the rocks on Dee- 

 side is granite. The limestone-districts are so limited in ex- 

 tent that it is impossible to arrive at any certain conclusion 

 whether the shock was felt with more or less severity in them 

 than in other places. It was distinctly felt in the limestone- 

 district of Tilwliilly in this parish." 



At Finzean, a little to the west of Banchory, Mrs Farquhar- 

 son, at lOh 30', felt distinctly " one shock or concussion which 

 lasted about 2", followed by a low rumbling noise which con- 

 tinued about 4''. The noise was in the earth. I was sitting 

 by the fire, reading, when I felt the shock. My chair seemed 

 to sway as from the motion of a ship on a wave of the sea. I 

 called to Mr Farquharson, who had just gone to bed * what is 

 that V He answered, ' I do not know, — but the bed is shakin<'
