K's Singh was a versatile scholar apart from being an administrator and an ardent practitioner of historical ethnography. In course of his long tenure of explorations on tribal matters, spanning over four decades, Dr Singh penned many essays on tribal movements, tribal peasant interactions, tribal customary law, tribal economy and so on. Much to the chagrin of historians and anthropologists, he had adopted a combined methodology of historical research and anthropological field work in making his points before the readers and decision makers.
