8*2 Nebraska Agricultural Exp. Station Research Bul. 16 
Fig. 18 — Germination box filled with sawdust and covered with burlap 
to retain moisture 
Fig. 19 — The germination box shown in Figure 18, uncovered. Note the 
much more vigorous growth at the ends of the box where the 
burlap was folded back and greater pressure exerted by the box 
standing on top. The germinative ability of the corn at the center 
actually equalled that at the ends. This illustrates possible experi- 
mental error in testing for germination
