[...] When the root-system of the plants on these plots was examined it was found that the first effect of water-logging was to restrict the roots to the upper layers during the first few months of growth and to change the general character of the root-system. [...] This is particularly the case in North Bihar where the flow of the rivers is soon checked by the rise of the level of the Ganges. [...] These movements of the river-level and of the general grounwater are illustrated in the curves opposite which represent the state of affairs of the river at Pusa and of one of the wells (about a quarter of a mile distant from the river bank) for the years 1910 1912 1913 and 1914. [...] IN the potato tracts of the Bombay Presidency the greatest enemy to the successful growth of this crop is the presence of the " ring disease."
