Excursions. 



The field excursions are advertised in the papers so as to be 

 within the reach of everyone, not only Club members but the general 

 public. The expense is slight, seldom more than street carfare. 

 Scientific men, both members of the Club and others at the request of 

 the Club, attend the excursions to direct interest and answer questions. 



In the spring of 1916, five excursions were held according to the 

 programme published in the April number of The Ottawa 

 Naturalist : 



No. 1, May 6. Rockcliffe and the vicinity of McKay's Lake. 

 Subject, Geology. Leader Dr. E. M. Kindle of the Geological Survey. 



No. 2, May 13. Cache or Catfish Bay, west of Hull. General 

 Zoology. Leaders: Mr. G. A. Millar of the Normal School, C. M. 

 Sternberg, and F. W. Waugh. 



No. 3, May 27. Fairy Lake and vicinity. Subject, Botany. 

 Leader, F. W. Waugh,'. 



No. 4, June 10. Aylmer Park and vicinity. Subject, General 

 Zoology. Leaders: C. Patch, F. W. L. Sladen, and F. W. Waugh. 



No. 5, June 17. The Experimental Farm. Subject, Horticulture. 

 Leader, Mr. W. T. Macoun. 



In addition to the usual series of spring excursions, the Club 

 organized an autumn excursion to Fairy Lake on which botany was 

 the centre of interest, special attention being paid to the different kinds 

 of seeds. The excursion differed in this way from the usual spring 

 flower study. The announcements for these excursibns were made 

 through the daily press and the attendance reached as high as thirty. 

 An effort will be made during the coming season to lead more of the 

 resident members of the Club to avail themselves of this interesting 

 way of getting acquainted with the common things of Nature. 



Lectures. 

 The lectures are planned to represent all branches of natural 

 science, and were given by scientists from several departments of the 

 Government service. They develop an appreciation of the scientific
