89. — On a Remarkable Noise Heard During a Forest Fire 
at Neguac. 
Read January 3, 1905. 
While in Tracadie in September last I was told of a remark- 
able explosion which occurred back of Neguac two years ago in 
July during a forest fire, and which was supposed to be due to 
the ignition of gas held in a peat-bog. The information seemed 
so well substantiated and the phenomenon itself of so unusual a 
character that I sought further information about it from a pro- 
minent and observant resident in the vicinity, one to whom I am 
indebted for much other valuable information, M. Romain 
Savoy, of Riviere du Cache. He writes me that the event is well 
known locally, apparently creating much comment at the time, 
and that he attempted to investigate the cause, even having the 
ground examined where it occurred. It was not truly an explo- 
sion, but a great roar, lasting about five minutes, and was heard 
but once. It occurred when a forest fire, driven by a warm south- 
erly wind, was burning with great force in a dense forest. In 
the meantime a heavy cold easterly wind sprang up, (the course of 
which could be followed by its accompanying clouds. It was 
when this wind, with its cloud, met the southerly wind and smoke 
cloud, that the noise was heard ; and M. Savoy’s explanation, 
locally accepted, is that it was the meeting of the cold and hot 
air which in some way produced an effect resulting in the re- 
markable noise.
