124. — On Temperature Measurements of New Brunswick 
Springs. 
Read June 4, 1912. 
New Brunswick is a wonderfully well-watered country, and 
amongst these waters are innumerable cold crystalline springs. 
Often and often in the summers, after physical enjoyment of 
their coolness and a visual delight in their clarity, I have turned 
to the intellectual consideration of their low temperatures and 
the causes. But my measurements of those temperatures thus 
far have been spasmodic and planless, and not over-careful, 
though I mean to reform in these respects for the future. In 
particular I have often wished I could follow the temperature 
changes of some large spring through all of the seasons, in com- 
parison with the fluctuations of the air-temperatures and with 
the mean annual temperature of the place, and could compare 
the temperature fluctuations of the same spring in different 
years and of different springs through the same year. No such 
measurements have yet been made in New Brunswick, easy 
and satisfactory though the matter would be for some scientific- 
ally minded resident; and it is largely in order to call attention 
to the problems and their interest that I present this note to 
the Society, especially commending the subject to the attention
