66 The Ottawa Naturalist. [Aug.-Sept. 



AcTiNOLiTE, West side of Ottawa Island, Hudson's Bay. 



This mineral approaches the variety asbestus but it is too 

 splintery to be of commercial value. It is greenish grey in 

 colour. The fibrous masses are sometimes six inches in 

 length. It will be noted that this mineral is found in 

 quite a different region from the others referred to in this 

 paper. 



The chief points of interest connected with this series of 

 minerals are: 



1 . The remarkable agreement between the variety of minerals 

 found in south Baffin Land and those found in other 

 regions where crystalline limestones form a prominent part 

 of the gneiss complex. 



2. The presence of cordierite, spinel, garnet, rose quartz and 

 ophicalcite suggests that in the future Baffin Land may 

 produce minerals valued for ornamental purposes. 



3. Mica, graphite, serpentine and actinolite are minerals fre- 

 quently mined economically.

QUEBEC DRAGON-FLIES. 



By Rev. T. W. Fyles. 



A few weeks ago I had the pleasure of a visit from Prof. E. 

 M.Walker, editor of the " Canadian Entomologist." Dr. Walker 

 is an authority on the Odonata, and he kindly examined some 

 of the dragon-flies taken by me in Quebec Province. He 

 identified several of them, and verified the names of the rest. 

 The following is a list of the insects, giving the locality in which 

 each was taken. It should be regarded as an appendix to my 

 paper on the Dragon-flies of the Province of Quebec, which ap- 

 peared in the 31st Annual Report of the Entomological Society 

 of Ontario.
