kindly thrown open to the excursionists on that occasion, 
as also on a previous one (1881), the diversity of the soil 
and region, afforded quite a diversity of flora, as well as of 
fauna. 
For example, Cypripedium parviflorun, Habenaria dilatata ? 
Arisema triphyllum, Gaultheria procumbens, Linnea borealis, 
Thuja occidentalis, Impatiens fulva, Oxcalis Acetosella, Good- 
yera pubescens, Pyrola elliptica, Thalictrum Cornuti and other 
plants were noticed in the low-lying grounds, between the 
“manor” and the Canadian Pacific Railway traek, whilst 
such species as Comandra umbellata, Saxifraga Virginiensis, 
Prunus Pennsylvanica, Vaccinium vacillans, Asclepias Cornuti, 
Quercus rubra, Adiantum pedatum, Aquilegia Canadensis and 
Rubus odoratus occupied the higher and dryer levels along 
the hill slopes and tops. It was a delight to meet with 
Cypripedium acaul2 in such numbers as were noted along 
the bluff of micaceous gneiss, close to the R. R. track, 
associated with Chimaphila umbellata, Rubus villosus, Prunus 
Pennsylvanica. The beautiful little “ blue-eyed grass ”— 
Sisyrhynchium mucronatum, noted for the rapidity with 
which it ripens or produces its fruit—was also observed 
in large numbers; this species is found skirting the edge 
of the Laurentides from north of Montreal westward to 
Ottawa and farther west. Besides the above, Polygala 
paucifolia, Lathyrus ochroleucus, Geum rivale, Dirca palustris, 
Lycopus Virginicus, Cypripedium parviflorum, Symphoricarpus 
racemosus, var. pauciflorus are amongst those species which 
are of usual occurrence, and of general interest along the 
Ottawa valley. 
A few plants have escaped cultivation and are spreading, 
viz. :—Arabis hesperidoides, Allium Schenoprasum and Conval- 
laria majalis.’ 
In order to ascertain in general, what the flora of the 
grounds surrounding the “ manor” was—a list of the 
species was made on the spot, subsequently systematized, 
and hereto appended :—
