the rainfall has been far above the average, and that the plats 
have been severely-washed by heavy rains several times the past 
season. Making comparisons of the crops from above plats, by 
groups as fertilized, we find that there has been a much higher

supply of nitrogen and phosphoric acid, than from the one receiv- 
ing no potash, and that the plats on which potassium sulphate 
was used gave a nearly intermediate yield. This is significant that 
the custom of dressing land with potash for potatoesis well founded.
