1897] Monday Afternoon Lectures. ii5 



Young Men's Christian Association. There was a large audience 

 consisting of students, teachers and many of the general 

 public. Much intere^ was added to the lecture through the 

 kindness of Prof John Macoun, who lent beautifully prepared 

 skins of the birds mentioned by Dr. Fletcher. A simple classi- 

 fication of the birds found in Canada was given and delightful 

 anecdotes of the habits of many species which had been observed 

 during a study of twenty-three years by the lecturer. A special 

 appeal for protection was made on behalf of the Pine Grosbeak, 

 Wax-wings and other birds which visit us in winter time. The 

 songs of our birds, the regularity of their migrations and the 

 continuous delight to be found in their study were treated 

 of in an enthusiastic manner which was highly appreciated by 

 those present. 



Rocks and Fossils. 



On Monday, 31st May, Dr. H. M. Ami, one of the Leaders 

 appointed last April by the Club, in charge' of the geological 

 section, delivered an interesting lecture on " Geology, with 

 special reference to the Ottawa District." In the course of his 

 remarks. Dr. Ami described, first, the leading kinds of rocks to 

 be met with in studying the various geological formations about 

 Ottawa. This done, he gave a careful description of the 

 different formations, pointing out their mineral, stratigraphical 

 and pal^Eontological relations as seen in the field. The best and 

 most typical exposures were then described and the localities, 

 where the best collections of fossil organic remains might be 

 obtained were pointed out. 



Many of the students of our educational institutions present 

 took notes on the lecture and asked numerous questions, to 

 which the lecturer replied. The lecture was illustrated by 

 means of diagrams on paper and on the blackboard, and also by 

 numerous fossil organic remains illustrating the geological 

 features of the formations met with in the Ottawa Valley.
