in thickness. Specimens of Saxicava rugosa and Macoma 

 Balihica were found in the clay and sand on Saturday, and on 

 former visits a few specimens of Leda (Portlandica) Arctica and 

 Balanus crenaius were collected. These four species live only 

 in salt water and their presence proves that these deposits were 

 laid down in the sea or on its shore, and therefore the relative 

 height of the land at Chelsea has changed at least four hundred 

 feet since their deposition. 



On returning to the station, Mr. Attwood called on Mr. R. H. 

 Campbell, who addressed the gathering, giving much useful 

 information regarding tree plantation and the need of better 

 preservation of certain coniferous trees whose reproduction is 

 slow owing to the seeds requiring two or three years to mature. 

 He also drew attention to the wonderful attraction exercised by 

 the sun upon the leaves, and to the fact, that when the leaves of a 

 tree happen to be small, there is always a greater number of 

 them to make up the requisite leaf surface. 



Mr. Eifrig followed, speaking on the migration of birds and 

 their habits. He stated that they were moved by two impulses, 

 food supply and the propagation of their species, that the latter 

 was the stronger, leading many of them to the far north, where 

 they were reared, from regions as far south as Bolivia and Peru. 

 Referring to the comparatively few birds seen during the after- 

 noon, he attributed it to two reasons, viz., the nesting season 

 and the depressing" state of the weather, which alwavs exerts a 

 quieting effect upon birds whose organisms are delicately balanced. 

 However, the following birds were seen: Chimaey Swift, King 

 Bird, Alder Flycatcher, Meadowlark, Blackbird, House Wren, 

 Goldfinches, Junco, Bank and Barn Swallows, Ovenbird, Black- 

 throated Blue Warbler, Hermit Thrush, Chickadee, Black- 

 throated Warbler, many Song, White-throated and Clipping 

 Sparrows, Blackpoll and Chestnut-sided Warblers, and the 

 Vesper Sparrow, who sang his loud and musical song as the train 

 started for Ottawa, thus concluding one of the most enjoyable 

 revels that the writer has ever had with Dame Nature.

i Carp, Ont. 



The excursion to Carp on May 29th was not so largely 

 attended as was expected owing to the uncertainty of the weather, 

 and vet there was a goodly number on board when the train left 

 the Central Station at 11 .50 a.m. On arriving at Carp the party 

 proceeded to the school house and was received there by the 

 teaching staff, who did all in their power to make the afternoon 

 an agreeable and profitable one. The school building is a fine 

 one, and stands on an eminence which commands a splendid
