tips, and often the entire leaf was affected. This characteristic be- 
came severe where 20 pounds were used. These same effects were 
noticeable in sections 1 and 3, but relatively large quantities were 
required to produce the symptoms. In section 1 there was no 
apparent change in color of foliage with quantities under 5 pounds per 
acre. The complete data are given in Table 2.

Table 2 shows that borax in small quantities materially affected 
germination, especially in section 2, and that there was considerable 
retardation in growth in the early life of the plant. The effect on 
germination and growth is shown in Plate I, Figure 1. The plants 
shown were dug from the various plats in section 2 on June 15, each 
being a representative plant from the plat on which it grew. Where 
200 and 400 pounds of borax were used, the seeds germinated, but 
the sprout withered and died without pushing through the soil. The 
plants from the 50 and 100 pound borax plats were abnormal, weak, 
and very badly bleached. : 
The weights of beans and vines tell the story of the final influence 
of borax on the production of this crop. In sections 1 and 2 its harm- 
ful effect is first noticeable with 5 pounds per acre, which increases 
in degree as the quantity added increases. In the broadcasted sec- 
tion there is not shown much influence from quantities under 10 
pounds per acre. 
Plates II and III show the Lima and snap beans which were 
photographed on July 17. In Plate II, Figures 1, 2, and 3 show the 
Lima and snap beans grown on the no-borax, 5-pound, and 10- 
pound borax plats, respectively. In Plate III, Figures 1, 2, and 3 
show the beans in the 20, 50, and 100 pound borax plats. Figure 3 
also shows the plats having 200 and 400 pounds of borax. Here it is 
seen that these higher borax plats have supported no vegetation 
whatever. The effect of the varying quantities of borax is apparent 
and does not call for further comment.
