They showed also that much of the physical history of the region, as well as of its human record, could be read only underground. It was found that during the existence of the two kurgans there had been a succession of alluvial growths with intervening degradations, succeeded in the end by a considerable thickness of irrigation silts. There were, therefore, three kinds of growths—natural sediments, irrigation sedi-ments, and culture-strata. It was clearly desirable to obtain some light on the relative rates of these growths, for, having this, if we should be able to determine the rate of either one in years, it could be applied to all, including the culture-strata.
There were sunk 24 shafts. Nine were intended to determine the thickness of the culture-strata and the character of the underlying natural formations. Two
