228 THE EARTHQUAKE OF MARCH 21, 1904, 



wherever possible. Names of many observers will appear in 

 the text. To all these, and to others, many thanks are due. 

 On the phenomena in New Brunswick, a short paper has 

 appeared by Mr. S. W. Kain ("Recent Eaithquakes in New 

 Brunswick "; Nat. Hist. Soc. of N. B., bull., vol. V, no. 11, June, 

 1904 ; pp. 243-245). It is to be regretted that more notes are 

 not available, especially in the gold districts or region covered 

 by them, between the Atlantic Ocean on the south and the 

 carboniferous rocks on the north. The author will be greatly 

 obliged to any who send him information from such or other 

 places, and it will be used in a supplementary paper later. 



For the purpose of serving as a guide to observers on future 

 occasions, the questions sent out are here reproduced. They 

 have been slightly amended from the original, to be better 

 adapted to the local conditions. Most of the information obtain- 

 ed thus far regarding this earthquake is too meagre to permit 

 of classification under the seperate answers, and will be given as 

 it was received.
