Mi: Clark : 1 am not saving that there is any. ^Mr. Presi- 

 dent. I am not. That tnbe has nothing to do with mv paper. T 

 will take it out. ( Laughter.) This is the tube we use at the 

 station, and it was perfeetly satisfactory to us. Tliose that want 

 to use glass tul)es, why use glass tubes. Of course, 3-ou will all 

 remember, if you have ever seen Mr. Chase's patent papers, they 

 provide for a glass tube, way back in 1880, the first jar they in- 

 vented, in the patent papers, provides for glass tubes. I suppose 

 3[r. FuUcrton has those same tulies. 



:\lr. Full.Tton: Xc 



\er saw one. 



Mr. Clark : The original glass jar was invented ]jy ]\Ir. 

 Chase, and that jar in the patent papers, I think provides for a 

 glass tul)e. Now. all these others have been taken from that. 

 :\lr. ('base bad on his glass tul:)es the little feet here, but of 

 course tli(\v were not as thin. The thing that I feel a little 

 funny al)Out is how can a very thin thing like that stop the flow 

 of water, to make trouble with the eggs. That is the only point. 

 It seems to me it must be something else that makes that, with 

 the ])ike perch, I should say — Mr. Thayer is more familiar I 

 should think it was the chunks of fungus and the eggs, isn"t 

 that it ? 



^fr. Thayer: 'I'hat is all we found. 



.:\Ir. Clark: And does not eft'ect the eggs so that they shoot 

 up here and there. It is the mass of fungus in there with 

 your pure eggs. But if tlie glass tube is what one man wants, 

 let him have it. One man may use tin, another lead, or some- 

 thing else. In the Detroit hatchery, we used to use lead — isn't 

 that right jNIr. Bower ? 



^Ir. Bower : Yes^ sir.
