Seite 91 - Him, piteous of his youth and the short space He has enjoyed the vital light of heaven, Soft disengage, and back into the stream The speckled captive throw. But should you lure From his dark haunt, beneath the tangled roots Of pendent trees, the monarch of the brook, Behoves you then to ply your finest art. Long time he, following cautious, scans the fly; And oft attempts to seize it, but as oft The dimpled water speaks his jealous fear.
Seite 91 - Just in the dubious Point, where with the Pool Is mix'd the trembling Stream, or where it boils Around the Stone, or from the hollow'd Bank, Reverted, plays in undulating Flow, There throw, nice-judging, the delusive Fly; And, as you lead it round in artful Curve, With Eye attentive mark the springing Game.
Seite 91 - There throw nice-judging the delusive fly : And as you lead it round in artful curve, With eye attentive mark the springing game. Straight as above the surface of the flood They wanton rise, or urged by hunger leap, Then fix, with gentle twitch the barbed hook : Some lightly tossing to the grassy bank, And to the shelving shore slow dragging some, With various hand proportion'd to their force.
Seite 91 - Of pendent trees, the monarch of the brook, Behoves you then to ply your finest art. Long time he, following cautious, scans the fly ; And oft attempts to seize it, but as oft The dimpled water speaks his jealous fear. At last while haply o'er the shaded sun Passes a cloud, he desperate takes the death, With sullen plunge. At once he darts along...
Seite 92 - The cavern'd bank, his old secure abode ; And flies aloft, and flounces round the pool, Indignant of the guile. With yielding hand, That feels him still, yet to his furious course Gives way, you, now retiring, following now Across the stream, exhaust his idle rage : Till floating broad upon his breathless side, And to his fate abandon'd, to the shore You gaily drag your unresisting prize.
Seite 10 - I captured a pair by means of a landing-net, and placed them in a bucket of water, and, being provided with an earthen vessel, I made my first attempt at artificially spawning and impregnating the eggs. This was accomplished as follows : I partially filled the earthen vessel with water, and, taking the female in my left hand, and...
Seite 22 - At the head of a spring we built a house, eight feet in width by twelve feet in length. We placed a tank, made of two-inch plank, four feet wide by eight feet long, and two feet deep, in the end of the building nearest the bank. The water from the spring enters the tank through a hole near the top, and escapes through a similar hole at the other end, from whence it is received into a series of ten successive boxes.
Seite 11 - ... color to a pale transparent yellow ; they were then placed in running water with the vessel containing them. On the 9th of January, one of the eggs was placed under a microscope. The egg, which at first had been a simple cell, was now multiplied into a countless number of cells, of different sizes, with traces of blood-vessels ; the eyes also being perceptible. On the 22d of January, we examined them again, and to our joy we found a young fish, which had just...
Seite 12 - The other portions of the fish are quite rudimentary, no other fins being perceptible, but in their place there is an attenuated margin, or fin-like substance, as on the tail of the tadpole, commencing where the dorsal fin should be, and continuing uninterruptedly around the caudal and terminating with the anal fin, or rather where it should be. This fin-like substance undergoes a constant change as the fish grows older. At fourteen days the dorsal, adipose, caudal and anal fins are plainly seen,...
Seite 9 - ... coarse and fine pebbles, the spaces or interstices between which were to be the future depository for the eggs. This peculiar construction of their beds, or nests, is highly essential to their preservation, as it protects them from being washed away by freshets, also from being devoured by small fishes, which are always prowling about seeking them for food. The male trout, at this time, was very beautiful, being decked out in the most gaudy colors imaginable, and his actions showed clearly enough...
