insects, and rocks, given as the objects were found in the open 

 field. 



In the way of botanical specimens, we have to mention a large 

 collection of interesting violets. Along the river, the silver maple 

 (Acer dasvcnrpum) was found growing quite abundantly among 

 the red maples. The former was easily distinguished from the 

 latter by its more deeply cut leaves. The green alder {Alnus 

 viridis), which is not found in many places about Ottawa, was 

 common near the river bank. 



Seventeen different kinds of butterflies were collected, the 

 rarest species of which was Thecla iiiphon, taken by Mr. Arthur 

 Gibson and also by Mr. A. E. Richard. Other species found by 

 Mr. Richard were Nisoniades juve?ialis, N. icelus, and Brentis 

 hellona. Dr. Fletcher secured a specimen of a rare longicorn 

 beetle, Anthi-ophylax attenitatus. 



Numerous Batrachians were obtained in a shaded ravine 

 beside a spring, such as the Wood Frog {Rana silvatica), the 

 American Toad {Bufo amerlcana); and Miss Wilson, of the Ladies' 

 College, at this place, discovered a specimen of Tree Frog, of the 

 species known as Hyla pickenngii, which species is of a fawMi 

 colour, and singularly marked on the back with an oblique cross. 

 All the specimens of Batrachians were small. A specimen of 

 Grass Snake {Liopeltis vernalis) was also captured by a boy and 

 held up for inspection at the time when the addresses were given 

 at the grove. 



Leaders who attended the excursion were Mr. W. T. Macoun, 

 the President of the Club, Prof. Macoun, Dr. Fletcher, Dr. 

 Sinclair, Mr. A. E. Attwood, Mr. Arthur Gibson, Mr Wilson, 

 Dr. Guillet, and Mr. Andrew Halkett. When assembled in the 

 pine grove, before returning to the city, the President called upon 

 Mr. Wilson, Dr. Fletcher, and Mr. Halkett to address the assem- 

 blage concerning respectively the fossils, batrachians, and plants 

 which had been found. The excursionists then returned to 

 Ottawa, and numbers of the members and others have since been 

 seeking to study out in closer detail the structure of special ob- 

 jects. All look back to that afternoon in the shaded woods and 

 open field as a promising incentive in connection with the future 

 work of the Club. A. H.
