The preceding experiments were conducted under identical 
conditions, and demonstrate that good beet seed will germinate freely 
in soil containing as much as 0.7 per cent, of white alkali, or sodie 
sulphate, but with as much as 0.1 per cent, of black alkali, or sodie 
carbonate, free germination of the seed is doubtful, and the action of 
the black alkali is scarcely, if at all, mitigated by the presence of an 
equal quantity of white alkali. The result obtained when 0.05 per
