The palynological [7.4] evidence, extrapolating that derived by Singh from his pollen-analytical studies of salt-lake deposits in Rajasthan, indicates that at the beginning of his Phase IV, *c.* 3000-1000B.C., the climate seems to have taken a sudden change to wetter condition, 'the period of maximum wetness appearing to last only up to 1800 B.C. Thereafter, the climate shows a small-scale oscillation to drier condition between *c.* 1800 and *c.* 1500 B.C., followed by a slight reversal to a relatively weak wetter condition, lasting to about 1000 B.C.' (Singh, 1977).
