384 ASSINNIBOINE AND SASKATCHEWAN EXPEDITION. 



warm, mellow weather we term Indian summer is a 

 periodical phenomenon in Canada, but the cause does not 

 appear to be quite understood. The characters of Indian 

 summer are more decided in the north-west than in the 

 neighbourhood of Lake Ontario. Sounds are distinctly 

 audible at great distances ; objects are difficult to discern 

 unless close at hand ; the weather is warm and oppressive, 

 the atmosphere hazy and calm, and every object appears 

 to wear a tranquil and drowsy aspect.
