unculus septentrionalts, a rare and IS eSoes species, were 
detected by the botanists,’ 
As to the birds of the district. Mr. A. H. Gallup wie 
‘* Forty species were listed, none rare. The following might be 
mentioned ; Warblers—Yellow, Black and White, and Black- 
throated Green; Redstart, Oven-bird, Water Thrush, Mourning 
Warbler, and many Wood Pewees, Red-winged Blackbirds, 
White-throated Sparrows, Purple Martins, Red-eyed and Warbl- 
ing Vireos and Wilson’s Thrush. The delightful song of the 
Catbird was noticed.” 
On the geology of Carp and environs, Dr. H. M. Ami, the 
leader of the Geological Section, says: ‘‘ Carp village is situated 
on the bank of a small stream of the same name, along the edge 
and top of a series of marine terraces made up of ‘‘drift’”’ materials 
deposited during later Pleistocene times, over the irregular surface 
of an Archean mass which crops out in numerous places and ex- 
poses gneisses crystalline limestone, holding various kinds of 
minerals. Immediately opposite the Canada Atlantic Railway 
station are the remains of a hill of gravel from which were ob-— 
tained the remains of two species of marine organisms: (1) a 
barnacle, probably Balanus Hameri ; (2) a shell, Saxicava rugosa, 
L. This hill, on which a house used to stand, has been cut away 
for ballasting the railroad track along the line of the Ottawa and 
Parry Sound Railway. Saxtcava rugosa.—Large and abundant 
specimens occur in the westerly portion of what remains of this 
once prominent feature in the landscape about Carp station, oppo- 
site the box factory and sawmill, near the old school house. The 
gravel is coarse; pebbles varying in size from that of a pea to 7 or 
8 inches in diameter occur throughout the mass, and a large pro- 
portion of them would average from 2% to 3 inches. Many of 
these, about 07%, are of Archean age. 
‘*Under the guidance of Mr. J. W. Gibson, to whose good 
management much of the pleasure of the day was due, the party 
skirted along the edges of the Laurentian ridge and returned over 
the rocks where iron-bearing gneisses—associated with crystalline 
limestones—syenites and granitoid or pegmatitic masses traversed 
by veins of quartz and occasional dykes of diorites or some other 
augitic materials, were seen to hold interesting minerals. In an
