"An elaborate memorial has now been received bearing the signatures of all the German missionaries. It contains many passages or expressions which make me fear that the Kols having embraced or intending to embrace Christianity expect to have their rights (real or supposed) vindicated by their priests and pastors. It would almost be inferred from one passage in the memorial that in some instances they are dissatisfied with their change of religion because they do not and that it leads to social advancement. It so happens that the rights which the Kols claim in the land are being investigated under an enactment especially passed and by Tribunal appointed for the purpose, therefore, it is very undesirable that any extraneous agitation should arise, the benefits asked for by the memorialists’ impressively on behalf of the Kols could be conceded in full only by depriving other classes-Hindu and Mohamedan-of something which they now enjoy."
