392 FISHING IN AMERICAN WATERS. 



A SIMPLE PROCESS FOE PEEPAEING A SPAWNING-BED. 



If you have a trout-pond, tap it at the sluice in the dam 

 with several pipes of two inches diameter, covering the ends 

 in the pond with fine wire gauze to exclude* young fish, or 

 the eggs of such fish or reptiles as are. enemies to trout. Con- 

 duct the water through these pipes to rows of boxes about 

 two feet wide and six feet long, the boxes from the head one 

 nearest the dam resting two inches lower than the one which 

 immediately precedes it, so as to produce a current sufficient- 

 ly swift in this artificial stream formed of a row, or several 

 rows of boxes, and each row formed of half a dozen boxes. 

 One pipe to supply each row of boxes, and then you may 

 have as many rows of boxes as you have water to supply, 

 always bearing in mind that the water must run continually. 

 The waste water, after it leaves the boxes, may be conducted, 

 by a ditch into the brook below the dam, or into a pond pre- 

 pared to receive the young trout. The bottoms of the boxes 

 are next covered to the depth of a couple of inches with sand 

 and small pebbles, upon which is laid a pavement of stones 

 from three to six inches in diameter. The water should be 

 as much as two inches deep above this pavement, and fill the 

 boxes two thirds full. The boxes are open at the top. Then 

 pour the fecundated roe equally over the paved bottom of 

 each box, and it will soon find its way into the crevices of 

 the stony bottom, and within from sixty to seventy-five days 

 the trout will be hatched, and a bag connected to the abdo- 

 men by an umbilical cord contains sustenance sufficient for 

 forty days, after which the tiny creature begins to seek food,, 

 and should be removed to its pond.
