First cast,—­to the right, straight across the stream, about twenty feet:  the current carries the fly down with a semicircular sweep, until it comes in line with the bow of the canoe.  Second cast,—­to the left, straight across the stream, with the same motion:  the semicircle is completed, and the fly hangs quivering for a few seconds at the lowest point of the arc.  Three or four feet of line are drawn from the reel.  Third cast to the right; fourth cast to the left.  Then a little more line.  And so, with widening half-circles, the water is covered, gradually and very carefully, until at length the angler has as much line out as his two-handed rod can lift and swing.  Then the first “drop” is finished; the man in the stern quietly pulls up the anchor and lets the boat drift down a few yards; the same process is repeated on the second drop; and so on, until the end of the run is reached and the fly has passed over all the good water.  This seems like a very regular and somewhat mechanical proceeding as one describes it, but in the performance it is rendered intensely interesting by the knowledge that at any moment it is liable to be interrupted.

This morning the interruption comes early.  At the first cast of the second drop, before the fly has fairly lit, a great flash of silver darts from the waves close by the boat.  Usually a salmon takes the fly rather slowly, carrying it under water before he seizes it in his mouth.  But this one is in no mood for deliberation.  He has hooked himself with a rush, and the line goes whirring madly from the reel as he races down the pool.  Keep the point of the rod low; he must have his own way now.  Up with the anchor quickly, and send the canoe after him, bowman and sternman paddling with swift strokes.  He has reached the deepest water; he stops to think what has happened to him; we have passed around and below him; and now, with the current to help us, we can begin to reel in.  Lift the point of the rod, with a strong, steady pull.  Put the force of both arms into it.  The tough wood will stand the strain.  The fish must be moved; he must come to the boat if he is ever to be landed.  He gives a little and yields slowly to the pressure.  Then suddenly he gives too much, and runs straight toward us.  Reel in now as swiftly as possible, or else he will get a slack on the line and escape.  Now he stops, shakes his head from side to side, and darts away again across the pool, leaping high out of water.  Don’t touch the reel!  Drop the point of the rod quickly, for if he falls on the leader he will surely break it.  Another leap, and another!  Truly he is “a merry one,” and it will go hard with us to hold him.  But those great leaps have exhausted his strength, and now he follows the rod more easily.  The men push the boat back to the shallow side of the pool until it touches lightly on the shore.  The fish comes slowly in, fighting a little and making a few short runs; he is tired and turns slightly on
