done to i^revent the young fish smothering; for I found that tlie 

 fry would not make tlieir way out of tlie jars unaided on account 

 of the comparatively large umbilical sac. 



The fry when first hatched are of a light color and seem to ad- 

 here to the side of the tank, l)0x or tray or any other object with 

 Avhich they come in contact. Those that we hatched were strong 

 <and healthy. They grew rapidly, and in their development ex- 

 hibited their wild nature and the instinct of self preservation by 

 quickly darting off to hide when alarmed by a person approach- 

 ing the tank in which they were confined. We retained part of 

 them until they were four weeks old and at the end of that time 

 they were an inch and a quarter long. We fed them on young 

 pike which seemed to be a suitable as well as very acceptable food. 



We planted 500,000 fry. 



I believe we are justified in claiming that our work in plant- 

 ing muskellunge fry during the past two years has shown results 

 of a substantial nature. In the Minocqua waters, where we 

 planted the frv hatched the first two years, more small muskel- 

 lunge weighing from one to three pounds have been taken dur- 

 ing this season than were ever taken before from those waters in 

 the same period in the memory of the oldest guide or resident. 

 We are gratified by the results of our first efforts in this work and 

 <?ntertain large hopes for the future. Already, in fancy, I see our 

 lakes again teeming with this splendid fish, and the value of 

 fish cultural work once more conclusively demonstrated in our 

 waters. 



Xumerous lakes in Xorthern Wisconsin, the habitat of this 

 fish, afford an extensive field in which to work, and, when once 

 well stocked, these waters will be a source of abundant revenue 

 to the state ; for no other fresh water fish is so attractive to the 

 sportsman and summer tourist. 



DISCUSSION OF MK. NEVIN's PAPEK. 



^Ir. Bower : How long were the fish held in confinement be- 

 fore yielding up their ova ? 



Mr. Nevin : Some of them a week or ten days. 



]\Ir. Bo\\-er: Our practice has been to catch the fish, spawn 

 fhem and let them go as quick as we could.
