1897] Field Excursion to Chelsea. 125 



the ideal — the religious side, the side of art and literature. A 

 love for Nature seemed to embody all these different sides and 

 brought us in touch with the truest and best. He was followed 

 by Mr. Blue, student from the Provincial Normal School, who 

 spoke on some of the botanical finds made during the day. The 

 Asters were conspicuous and other members of the family of the 

 CoinpositcE. On behalf of the students, Mr. Blue expressed the 

 pleasure they had experienced during the day. Mr. Clark then 

 added a few remarks and emphasized the remarks made by Mr. 

 Blue. His remarks were received with deserved applause. 



Dr. Ami then addressed the gatherin'g on the subject of 

 geology. At Chelsea, both extremes in the geological scale 

 meet. The newest or Pleistocene formations were seen to great 

 advantage, consisting of marine sands, gravels, clays, covering or 

 overlying unconformably over the oldest or Arch^an rocks of 

 the district. These two sets of rock-formations are the most 

 discussed at the present day and afford a vast amount of interest- 

 ing material for special study, with good prospects of making 

 interesting discoveries and elucidating some of the intricate 

 problems still existing in these the opposite ends of the geological 

 scale. At " The Ravine," near Old Chelsea, the geological sec- 

 tion had repaired, and there examined the crystalline limestones, 

 ophi-calcites, besides micaceous and other gneisses, serpentine 

 rocks, &c., of the district. Glacial striae, an interesting glacial phe- 

 nomenon was observed in the bed of the stream as indicating 

 dearly the bygone period of glaciation. A glacier once descended 

 th« slope in the general direction of the present course of " The 

 Ravine." This might be called the Chelsea Glacier. 



Other glaciers existed, whose glacial strias and other mark- 

 ings are clear near King's Mountain, between the main mountain 



massif and the spur above \^x. Bourinot's residence, above King's 

 Mere (Humboldt Glacier). These striae were observed at a 

 previous excursion of the Club. 



Along the Gatineau Vallc}^, in the beds of most of fhe 

 streams which discharge their waters into the Gatineau River,
