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.
