Earl}' on the morning of March 21st, 1904, a widespread 

 earthquake was felt in New England, New Brunswick, and 

 Nova Scotia. On the whole, its violence was considerably 

 greater in the first named region than farther east. In the 

 Maritime Provinces, it was greatest in certain distri(;ts, rather 

 erratically distributed. 



Such an earthquake naturally excited much interest, and 

 newspapers gave considerable space to accounts of its effects. 

 The United States Geological Survey began an investigation of 

 it, through Professor Harry Fielding Reid, of Johns Hopkins 

 University, Baltimore, Maryland. For the purpose of compiling 

 all possible information in a systematic manner, a blank sheet 

 is sent to observers whenever an earthquake is to be studied by 

 the Survey. Dr. Reid requested the author to gather such data 

 as could be found for Nova Scotia, and in the pursuit of this 

 task the information was collected which forms the basis of this 

 paper. It is published wnth Dr. Reid's permission. 



It IS impossible to thank, individually, all who have been of 

 service in this connection. Especial mention should be made of 

 that given by Dr. A. H. Mackay, Superintendent of Education 

 for Nova Scotia, who very kindly placed the Journal of Educa- 

 tion, the official organ of the department, at the author's service 

 for distributing questions ; and who collected the answers
