sides three inclics lii_q;li and fdled willi <;ravcl. The pnuA was 

 then filled with water and willow l)rnsli laid in N'-shape. the butt 

 ends of the l)rnsli l)eing erossed at the pointed end of tlie V^ beinj:^ 

 placed around each spawning bed, forming a perfect enclosure. 



Willow brush with tlie butt ends shar])ened and stuck in the 

 bottom of the pond was also ]ilaced around tlie spawning boxes to 

 afford seclusion for the spawners. 



May 29th the spawners, 42 in all, almut an e(|ual nvunbcr of 

 males and females, were transferred to the spawning pond; the 

 temperature in the pond being about 66 degrees, a change of 11 

 degrees from the j^ond from which they were transferred; the 

 spawners were put in near the inflow pii)e and the change of 

 temperature did not seem to affect them in the least, but as I 

 had expected, it caused the ova to rii)en rapidly and within twenty- 

 four hours they began to pair and spawn, and in nine days from 

 the time they were ]ilaced in the pond tlu' last pair had spawned; 

 out of the whole number only two pair used the spawning boxes 

 and one pair spawned in open water on fine sand. 



The eggs hatched out in eight days and wdien the fry were 

 about a month old I transferred what T estimated at 20.000 to an 

 adjoining pond, collecting them with a one-eighth inch mesh 

 conmion sense minnow net, the most of them being taken about 

 sundown around the inflow pipe. 



In the same pond with the fry I placed a large niunber of 

 eyed carp eggs, laid on moss, the carp when hatched to serve 

 as food for the young bass. This experiment proved a failure, 

 for within a month the carp had grown so rapidly that they were 

 as large as the bass and were destroying all insect life and mak- 

 ing the water very muddy. 



Wooden boxes two feet square with slat sides one-half inch 

 apart and supported by stakes driven in the bottom of the pond 

 were then placed at dififcrent ])oints in the j^jud and ground 

 crayfish placed in these fed for the balance of the season, but the 

 carp kept the water so roily that the bass did not seem to thrive 

 and when the pond was drawn off in Se])lend)er less than fifteen 

 per cent, of the number placed in the pond were found. 



The original spawning pond was well stocked with chubs 

 and shiners, which spawned about the same time as the bass. 

 About the ist of August I partitioned off about one-third of this 

 pond near the inflow ])ipe with one-inch mesh galvanized wire 

 fencing, supported by stakes driven in the bottom of the pond and 

 extending ten inches above the sm-face of the water, this fence 

 being put in to allow the young bass to feed on the minnow fry
