Dyche. — New Slate Hatchery for Kansas 175 



Mr. Geserich : Suppose you wanted to drain Pond No. 32 for 

 example? 



Professor Dyche: Pond No. 32 is on the south side of the hatchery 

 and one of the farthest from the river. It will he drained through the 

 pipe that has been laid under its north bank. The water will enter the 

 drain pipe at the northeast corner. This same drain pipe you see [in- 

 dicating on map] leads almost straight north to the river. Ponds 

 Nos. 31, 30, 41, 39, 40 and 42 you will notice discharge their water into 

 this same drain pipe ; there are several drain pipes leading to the river, 

 making a number of almost separate systems. 



Mr. Geserich : In other words, you have runways for each and 

 every pond? 



Professor Dyche: Yes. I have another blue print; one that shows 

 every drain pipe and runway. There are usually 8, 10 or 12 ponds 

 hitched to any one system or runway; but these eight-inch pipes lead to 

 and connect with larger pipes that carry the water to the river. 



Dr. Tarleton H. Bean, Albany, N. Y. : What provision do you 

 make against the crayfish working in those embankments? 



Professor Dyche: There is no provision for that. Crayfish have 

 never bothered our banks. A bushel or more of crayfish was once 

 dumped into one of the bass ponds and they soon disappeared. When 

 we drain the ponds we do not find any of them. 



Dr. Bean : But how are you going to prevent crayfish from boring 

 through the embankment from the outside? 



Professor Dyche: In one sense of the word there is no outside to 

 the embankments surrounding such a system of ponds. W T e have one 

 embankment running right up against the river in the old hatchery 

 and we liave never been troubled with crayfish boring in it. I do not 

 know of a single case. This river is well stocked with channel catfish 

 and black bass. These fish may keep the crayfish cleaned up; however, 

 crayfish have at times in the past been purposely placed in the river. 



Dr. Bean: Then there are no crayfish left. One of our problems 

 is to prevent them from making trouble. Have you much frost there? 



Professor Dyche: Very little. The vitrified clay pipes will be 

 placed from tbree to five feet underground. 



Mr. W. T. Thompson, Fairport, Iowa: If anyone were to ask me 

 for a definition of the word enthusiast, I would simply point him to 

 Professor Dyche and say : "There is your enthusiast personified." T 

 do not believe Professor Dyche's applications will be limited to the 

 state of Kansas if he furnishes the farmers fish weighing tbree pounds. 

 I remember hearing of one member of this commonwealth (Missouri) 

 sending in an application to the government for catfish. He was noti- 

 fied the fish would arrive by car at a certain time. He went to the car, 

 the captain passed him out several cans of fish, he took off one of the 

 covers, looked inside and saw that the fish were only about tbree or 

 four inches long. Turning his nose up in disgust he said as he walked
