After 10 minutes' soaking all the seed grew, but after one hour's 
treatment all but 2 kernels out of 50 were killed. A light application 
of the solution at the rate of about 3 ounces to the gallon of corn 
produced no effect, 49 kernels out of 50 growing, and the plants being 
uninjured and of maximum height after 3 weeks. 
The more important of these statistical data are brought together 
in the table following.
