trials in 1883 showed that sprouted seed air-dried for seven days, 
and then replanted, would renew growth. The per cent. germinat- 
ing at the successive trials were as follows: 
Germination per cent., same seed, each trial. Total days air-dried.

The comparative hardiness and prolificacy of our species, as 
determined under similar conditions of spacing and planting, is

These results for prolificacy are not, however, strictly compar- 
able, as Prolificacy is determined largely by the spacing of the 
Plants. Thus in a trial with Waushakum flint corn. 
1 plant, per hill, the yield per plant, 3.5 good ears and 1.1 poor ears.

: Most sorts of corn will germinate when quite unripe, in the 
milk or before hardening of the kernels has taken place. The 
aig flinty the corn the earlier and more certainly does the germi- 
Nation occur, The order in my trials has been flint, sweet, dent.
