they were held in shallow baskets made of window screen. When a 7 x 11 
inch basket containing a quart of seed was heated on the shelf of an electric 
or gas oven of such size as to leave a margin of 2 to 3 inches for circulation 
of air, the seeds in the bottom of the pan always became very much hotter 
than those on top and were killed before those on top reached a temperature 
effective for destroying the anthracnose fungus.

In other tests, a larger oven was used with a tier of 5 baskets 
14 x 9 x iy 2 inches, each containing a quart of seed. These baskets, kept 
apart by putting y 2 inch wooden strips across the top were stacked in such 
a position as to leave a marginal space of 1 inch at the sides and 1 y 2 inch
