ncer, Professor Hoad, and myself visited Mr. Buck at Xeosho, Mo., 

 and examined the government hatchery that he is directing. 



Mr. Worth : I will venture the assertion that Professor Dyche has 

 the largest and most comprehensive pond system in the United Stales 

 and perhaps in the world. I certainly admire it. 



Professor Dyche: There is one part of the station planned as you 

 see on this map (indicating) that will not be finished at present. It 

 will be built after the present station is completed. I refer to the re- 

 modeling of certain ponds and the adding of a dozen or twenty more 

 which have already been planned. We will build 83 new ponds now 

 and after that there will be enough more to build to make 107 ponds 

 which will cover about the same number of acres of water. 



Mr. G. W. X. Brown, Homer, Minn.: Don't you think it better and 

 more economical to make your ponds more regular in shape, so that 

 the drain pipe lines will lie straighter? 



Professor Dyche: That is a good question. This ground is very 

 peculiar. There are bumps and hollows, tips and downs; and the 

 ponds really located themselves in natural depressions; it will only be 

 necessary to remove enough dirt to give the pond basin proper shape 

 and to make the embankments. Therefore they are by nature irregular 

 in shape and size, but this is immaterial for tish-cultural purposes. It 

 will make construction economical, because we take advantage of the 

 natural contour of the ground 



Mr. Brown: The topograph)- of the ground shapes the ponds? 



Professor Dyche : Yes. 



Mr. Buck: You have to dig under each of your embankments to 

 make your outlet pipes? 



Professor Dyche: The pipes will lie laid before the embankments 

 are built and will be under the dikes. The work will be done in such 

 a way under the direction of the resident engineer that one part will 

 not interfere with another, but the pipe lines will go in first and the 

 earth will be filled in over them. 



Mr. Buck: If there should be occasion to repair them you would 

 have to dig pretty deep, would you not? 



Professor Dyche: Yes, but the pipes will be directly under the em- 

 bankments, so that they can be easily reached; we expect to put in a 

 system that will not need to be dug up, except perhaps in rare instances. 



Mr. Buck: After you get your embankments built they will be some 

 ten feet under ground, will they not? 



Professor Dyche: That is true: but the pipes will be accessible ii 

 it is ever necessary to dig any of them u\\ 



Mr. Thompson: Professor Dyche has told us of a number ol 

 pamphlets he has written which have been issued by the state. I sug- 

 gest that he write just one more, on the subject of: "How 1 Did It." 

 1 think it would be a good lesson to all the members, and more espe- 

 cially the state commissions, to learn how he manages to have the state 

 of Kansas build one large hatchery instead of half a dozen little one-
