In the compilation of the catalogue it is intended to index 

 the species on the regular card-catalogue cards 5 in. x 3 in., 

 which will be supplied to the members. A single species will 

 be listed on each card. The card will thus contain the infor- 

 mation which it is intended to include in the catalogue. For 

 example, the Spruce Budworm, Tortrix fumiferana Clemens, 

 would be indexed and listed as follows : 

 T. fumiferana Clemens.

 The catalogue will be published, under the editorship of the 

 writer, by the Geological Survey of Canada, by arrangement 

 with and the consent of the Minister of Mines and the Director 

 of the Survey. It will appear in parts as the different orders, or 

 families, in the case of large families, are completed, and its 

 publication will necessarily extend over a number of years. 



GENERAL EXCURSION TO CHELSEA. 



The general Excursion of the Club to Chelsea on May 2 7, 

 was a most successful one. The attendance was fairly large 

 and included many normal school students. The afternoon was 

 spent chiefly in Gilmcur's Grove and along the river bank. 

 Most of those present were interested in botany, so under the 

 leadership of Dr. Blackadar and Mr. J. W. Gibson, the party 

 first visited the falls and then at once started to gather speci- 

 mens. Only a few T of the mere interesting ones are here noted. 

 Among trees the Striped Maple (Acer pennsylvanicum) and the 

 Mountain Maple (.4. spicatum) were in fruit. No doubt all the 

 species of Acer could have been discovered, but the others were 

 past the flowering stage. Among the herbs that have a more 

 or less aromatic or edible root the following were noted: 

 Wild Sarsaparilla (Aralia verdi-caulis) , the Dwarf Gin c eng 

 (Panax trifolium), the Toothworts (Dentaria lackiiata and D. 

 diphylla), the Wild Ginger (A sarum can adense) and the Indian 

 Cucumber-root (Medeola virginiana). 



The lily family is well represented at this time in the woods. 

 Some well in fruit including the Bellworl (Uvularia perfoliata), 

 the Dog's-tooth Violet (Erythronium americanum), the Purple 

 Trillium and the large white one, (Trillium crcctum and T.
