 of several of ihtse, as also their usefulness to man and other creatures. 

 He had observed that a very large proportion of our commonest plants 

 in open places were introduced from Europe. Many of thtse, as the 

 thistle for instance, had become very noxious weeds. The majority of 

 plants met with during the day were common place specimens. Up- 

 wards of sixty different species were observed and noted in blossom. 

 Of these the Golden-rods and Michaelmas Daisies formed a conspicu- 

 ous lot. The following representatives of the Golden-rods (.^o/idai;o) 

 and Michaelmas Daisies {Asfer) were jotted down.

Epiphegus Virginiana and Rudbeckea hiria, one very humble and 

 the other a very conspicuous flowering plant were also collected and are 

 worthy of note. Of trees, the elm, linden, maple, oak and birch trees 

 are conspicuous and beautiful at North Wakefield. It is expected that 

 the list of species observed on this occision will be greatly increased on 

 some future visit by the Club to the locality. 



Prof. Macoun was then called ujjon to address the gathering, and 

 dwelt at length upon the relation of knowledge acquired from books 

 and of that acquired from personal observation and contact with 

 Nature. He also described the forest trees which were to be seen all 

 about, and applied the principles he had laid down in determining 

 these at a distance. 



Dr. Henry M. Ami s])oke next. In a rapid manner, as the time 

 for re-assembling at the station was fast approaching, he gave a general 

 sketch of the geology and physical geography or history of the district. 

 The rocks consisted chiefly of a hard compact, more or less coarsely 

 crystalline, syenite, or Hornblendic granite, with a tendency to lamina- 

 tion or foliation, resembling gneiss. This primitive or Laurentian rock 

 — fundamental gneiss, sometimes called— was seen to be intersected
