140 Thirfij-sevcnth Annual Meeting 



Mr. Fullerton : I believe that soon we will all be using ce- 

 ment. 



Mr. Clark: You can put water in in twenty-four hours. 



,Mr. Fullerton : Yes, in six hours. 



Mr. W. H. Safford, Conneaut Lake, Pa. : How many rows 

 of troughs have you in your perch battery ? 



A. Four, one above the other. 



Q. And your jar standards — what provision have you made 

 for those ? 



A. I am glad you mentioned that. ^Ye have here a con- 

 tinual shelf for the Jars to set on, and through that shelf there is 

 a pipe. 



jMr. Safford : Did you give any estimate of about what the 

 weight is for each trough and about how many troughs that 

 floor would stand? For instance, at my hatchery in Crawford 

 county the water supply is limited, and in order to get at a pro- 

 duction that we think the hatchery is capable of putting out, 

 we get our increase in the number of troughs. I have eight, one 

 above another in my liattery, and in that Avay it gives us34:3 jars 

 in one battery. 



Q. That is, on both sides of the battery, is it? 



j\Ir. Safford : Yes. Do you suppose that the first trough in 

 your battery would hold up, say eight of those? 



A. Yes, I think it would hold up twenty or thirty. These 

 standards are all made of cement right from the floor. 



Q. What are the dimensions of the standards? 



A. Four by four. The shelves that the jars set on are ce- 

 ment, built into the standards ; it is all one solid piece of cement. 



Q. Do you make these troughs separately or build them all 

 together ? 



A. We build them right in there. 



President: This is a paper of unusual value and is broad 

 enough to cover the general cement work. 



Mr. Clark : I do not want to advertise myself nor the Clark- 

 Williamson box — the only box I ever got up ; but I will say for 

 the benefit of the members here that the box known as the Clark
