leading to the left bank of the Mississippi river which was 

 followed down to its mouth, at Marshall's Bay. In the absence 

 of the president, Dr. H. M. Ami was in charge of the party, and 

 before scattering in the woods and forest adjoining gave out the 

 programme of the day, pointing out the leaders who would take 

 charge of the various branches of the Club's work. Mr. W. J. 

 Wilson of the Geological Survey led the geologists and before 

 evening was able to report some very good finds. Principal 

 Honeyman, of the Aylmer Academy, led the botanists and

 of Ornithology and answered any question put to her regarding

 Unios and other forms having been noted. At noon a halt for
