 the vitality of its eggs, is more easily obstructed in its 

 passage. 



BULL TROUT have the most hardy temperament, being 

 more vigorous than the salmon, and owing to this, gen- 

 erally succeed in reaching and occupying the best and 

 most favorable spawning beds, before the salmon put in 

 an appearance. 



With the SALMON we have dealt under the heading of 

 " Habits and Haunts of Fish." From a piscatory point 

 of view, it is a truly noble fish, and affords splendid 

 sport, as every angler will corroborate who has the pleas- 

 ure of landing a good lively fish, after a hard and heavy 

 fight. Upon salmon fishing as a sport much might be

 for the time being his whole soul is thrown into the 

 pursuit. Salmon fishers now wander far-a-field for past-

 of the salmon their one object in life, roaming over the 

 vast area of the European and American continents, and 

 of late years the boundaries of these have been over-

 proved so fertile. The popularity of salmon fishing has 

 increased something like a hundred per cent, during the 

 last half-century. Since the opening up of the Scotch 

 Highlands by the royal steam route, branch extensions 

 have rendered districts, once remote, comparatively easy 

 of access, and a part of the brief vacation of the most
