We live in the begi•ttivg of the cement age; no, I will say that we are living in the cement age. They are building almost every kind of plant tha•: can be built with wood, iron, stone or steel and using cement to do. it. Today we see stately buildings, immense bridges, /,'rear elevators--all constructed of cement. But the pnrpo.se of this paper is to show wha4 can be done with cement by the fish e•tltnrJst. Various materials have been used, wood, perhaps to a greater extent than any other,
... than any other, tin, sheet iron and various compositions but: none that gave entire satisfaction; sheet iron and tin fo.r the reason of its elastieitv not being stiff enough; wood for the reason that it was short lived and conse-Amer•ca• Fisheries Society 137 bit of material including labor, has to. be contracted for the first cost above wood is about fifty per cent. A great pai% of this is for the frames that must be made and as the niost of them must be cut away, they, of e.ourse, become useless. Receiving tanks for fry and frames for the p/eking troughs, one can be used for making several. Also all frames for the legs can be used over by bolting them together and when cement is hard unscrew the bolts and they fall apart and can be m-used. Now, I ]rove written this paper for the purpose of drawing the attention of the members of this association to the use of cement in constructing troughs for hatching fish. I want you to ask questions and i shall answer them to the best of my ability. There is no question in my mind about the super/o• qualities o.f cement over all other materials, and I here make this prediction that inside of ten )'ears no other material will be used by the fish eultnrist in the em•struetion of buildings and troughs.
