were given in the different rooms, while Miss Edith Farr 

 gave a description, in the Herbarium rooms, of the progress 

 of herbarium work. 



October j. Dr. Miller, President, in the chair. Miss 

 Edith Farr spoke on "'Summer Botanical Studies in the 

 Mountains of Western Canada." She briefly described the 

 trip across the continent, and then gave an account of the 

 localities visited, viz., Banff, Lake Louise, Field and Emer- 

 ald Lake, in the main range of the Rocky Mountains, and 

 Glacier in the Selkirk range. She called attention to the 

 fact that the forests at these high altitudes, 4,000 to 5,000 

 feet, are composed entirely of conifers ; at Banff principally 

 Pinus Miirrayana and Picea alba. At Lake Louise and 

 places further west Engelmann's spruce takes the place of 

 the latter. Lyall's larch (Larix Lyallii), was seen only at 

 Lake Louise at a height of 6,000 feet and upward. In the 

 Selkirks there is a greater variety of trees, including in addi- 

 tion to those named the Douglas fir and western cedar 

 (Thuja gigantca). Along the streams and on the moraines 

 of the glaciers, alders, willows, birches and other shrubs are 

 scattered. Some of the flowers of the region are similar to 

 those found in the East, but the majority are western forms, 

 while a few are purely local. The alpine herbaceous plants, 

 such as species of Saxifragas and Epilobium are of special 

 est. A collection of about two hundred and eighty herba- 

 rium specimens was shown and a few of the more striking 

 forms were commented on, such as Epilobium latifolium. 

 Rhododendron albiflorum, species of Vacciniiim and Mitclla, 

 also two species of Dryas. 



Dr. Miller then gave "Botanical Notes on European 

 Travel." The party with which he traveled landed at Gibral- 

 tar, where Antirrhinum and other genera were noted on the 

 fortress rocks. The Alameda or Public Gardens were in 

 beautiful condition and contained many types of interest, 

 such as Aloes and Agaves, some of which were in bloom on 

 a previous visit. Next morning the party proceeded to
