NTew York, May fi.- The Board of Indian Commissioners unaniraously adopten a report ye8terday on the Freaidenl's Inilinn policy. After spcaking of the causes which led to the revolt of tho Modocsand the assassination of Üearal C.-mby and Peace Commiasionar Thomai, thuysay: "A treaehery so base admita of no palliation, nor can any punishment meted out to tho pprpetrators of this crime be too SHvere." The Módoo war.it is held, howevor, eannot becharged against. tha President's poaoo policy, and it is ilso iitinned tliat the misdeeds' of individual Indiana or bapda should not bo charged againet the innocent or upon the whole race. The red man has no frienda to take hi :ude of the story, and no degree of exaggeration or falsehood ia too gross to be unhesitatiiifíly áfccepted by the public miud against hiin. The report aleo saya tliat it hns never been tlio oxpeotation of the friends of the present Indian policy that it would in the short period of a few years civilizo tho savage tribes, nor could it be expected to bring the red man in three years to beoome as free froni crime as the white. It is the opponents of this policy whu exject the Indian to be more freo trom criiuinality than jjooplo of our most civilized communities. Four years of tria! have proved tho peace poliey a sueeess, and with the exceplion of a contest with a few bands of Apaches and the present sfrugle with a handful of Modoc brave?, the country has been saved froni Indian wars. Christian denominations are invited to oo-operate in this work.
