In Table VI results of the analyses of corn (Zea mays), wheat, peas 
(Pisum sativum ), and oats (Avena sativa ), grown on plots at New Orleans, 
Ta., and Dallas, Tex., are recorded. The entire plants, which were 3 
months old and small, were used. The com and wheat plants took up 
equal amounts of boron. Soluble boron was found in all nine samples of 
soil from New Orleans, while only two of the five samples from Dallas 
contained any. The peas absorbed more boron than the oats, especially 
in series 1,2, and 3.
