gas, coal, iron ore, salt, gypsum, and gold, silver and copper ores. 

 The best known of these, and possibly one of the most important, 

 is the oil, which is known to occur as seepages at points from one 

 end of the region to the other. With the exception of placer 

 gold from the Omenica and Cassiar districts, however, no pro- 

 duction has yet been made of any of these minerals. 



Furs are the chief products of the region at present exported, 

 and the Mackenzie river region is considered by the Hudson Bay 

 Company to be the best fur-producing portion of Canada. 



LICHENS FROM VANCOUVER ISLAND. 

 By G. K. Merrill. 



The lichens here commented upon were collected by Prof. 

 John Macoun in the vicinit}' of Sidney, Vancouver Island. With 

 two exceptions, the plants are new to the Canadian flora, and 

 several are recorded as hitherto unreported from the North 

 American Continent. Other interesting discoveries of Prof. 

 Macoun await future comment.

Branches of trees, Sidney. 



Remarkable because of the main branches showing articula- 

 tions in the manner of U. articulata, and from the fact that 

 the cortex here and there is papillose or papillose-scabrous.
