except Lake Erie and the Georgian Bay, where it is quite common. Us 

 northern range is not yet clearly defined, but does not probably extend 

 beyond the height of land. 



Spawning takes place early in spring, soon after the ice goes out, in 

 shallow water about the reed beds. Here the females deposit a large 

 number of eggs, from which the fry hatch in from fifteen to thirty days, 

 according to temperature. 



The "Lunge" is, except at pairing time, a solitary fish, usually lying 

 concealed among aquatic plants at the sides of channels, or in open lakes, 

 beneath shelving rocks, from whence it darts upon every living thing 

 unfortunate enough to come within its reach and small enough to become 

 its prey. 



When taken in the autumn, at which time it is in high condition, its 

 flesh is firm, flaky and of good flavour, and its fighting qualities at their 

 very best. In summer it affords comparatively little sport and its flesh is 

 apt to taste weedy. 



Lender favourable circumstances Mascallonge attain' an immense size, 

 fish of eighty to one hundred pounds' weight having been taken in various 

 places. We do not often see such monsters now, but specimens ranging 

 from thirty to fifty pounds are captured every season.
