1) Crop damages were investigated in two varieties of rice plant "Tozan No. 59" and "Chukyo-Asahi" by comparing two plots, one caught in the storm and one guarded by a wind break. No injury due to the storm was found in the latter plot. 2) In "Tozan No. 59", the plants attacked lodged entirely and the nutrient translocation into kernels was checked remarkably for a few days, resulting the inferior grains remaining on panicles as blasted or chalky kernels, while the superior grains continuing their deverlopment barely into deformed or milk-white kernels, with the exception of some vigorous grains among them maturing into ordinary kernels. The yield of rice was 70 percent of that in the guarded plot. 3) In "Chukyo-Asahi", the leaves were splitted into two or three parts and the hulls were slightly chafed in the plot caught in storm. Accordingly, the kernel development was somewhat checked, and chalky, deformed, milk-white and brown kernels increased. The yield of rice was about 10 percent lower than that in the guarded plot.
