Sax Francisco, June 9. - JJispatches from Boyles' Cnlnp, dated yesterday, relate tbc p&rtioulan of an atrocious massacre ot' Modoc prisoners, it ia supposed by Orogon volunteers. Saturday uiorniug James Fairobild and about a dozen otíier men left Fuirchüd's ranch on Cottonwood Creek with seventeen Modoc captives, men, women and childron, including Shaeií-Nasty Jim, Bogua Charloy, Tebee Jack, Pony, and Little John, ïhe Indians were in a wagon drawn by four nuiles. At the crossiug of Lost Kiver the party encountered the Oregon volunteers under command of Capt. Hiser. ïhe soldicrs gathered about tho wagon and quöstioned Fairchild. The latter told theni the Modocs were all HotCreeks except little John, and that there were no charges agaiust them. Fairchild undertook to push on to Boyles' Camp, and the volunteers retired to their camp noar Crawley's. On the road he noticed two men ahead, riding to Itock Point as ií' to intttrcept him. When the team approachfd one presented a uf-edle gun at Faiichild, saying "Uet down, you oíd white-headed villain." " By what authority," said Fairchild. " By mine. I am going to kill the Indians and you, too," was the reply. Thu leader canght hold of the mules, unhitched them, and cut tho hfirness. Fairchild, clinging to the linea, loaped to the ground. The poor wretches implored íor merey and begged Fairchild to save them. The warriors were unarmed, and knew that resistance was useltss. They were the coolest iu the party, though facing inev itablo death, but the women uudchildren shriekod groaued and wept piteously. Fairohild had nothing but a srnall pistol and sis inches frora his ear was the muzzle of a neodle-gun. Ha says the tears carne to nis eyes and he miugled hisvoice with those of tho Mcdocs in hoe that the massacre might be avoided. "Oh ! it was a terrible scene I shall forget. I shuüder when I think what 1 saw and heard. The tearful voioes of those vTmen and chüd'ren still ring iu ray ears. But the cowardly hounds were not to be balked. A shot and Little John laydoad in the bed of the wagon, a bullet in his brain. Tho mules dashed away with Fairchild and tangled him in the liues. Five more shots iu rapid succession, and Teohe Jack, lJony, and Mooch, the remaining warriors, were dead. Little John's squaw had a frightful wound iu her ihoalder. Awaj" ahead in the road in the direction of Boyhjs' Camp was a cloud of dust, indicating the approach of a team. The murdeiers espietl the dust and in a moment were ïidina: rapidly away. geant Murphy, of Battery G, Fourth Artillery, witb. ten meu and teamsters, came by the team. The Sergeant took charge of affaiis and remaiued with his meu on the ground. Fairchild and the teamster, the wounded squaw and her twoohildren came on, and at two o'clock this morning Fairchild reached Gen. Davis' Headquarters and rolated liis story. Teams with an escort were at once sent out after the prisoners, dead and alive. Ko steps were taken tor the apprehension of the felona who performed the bloody work. It is generally supposed the üregou volunteers are the guilty parties. Fairchild is of that opinión hiiuself. The warriors killed wero not cliarged ■with uiurder. Those who knew them best say they have only participatcd in open fights. Every ono here condemns the affair as atrocious and without c-xeusp. There is no doubt but the uturdors were oarried out upon a carried out upou a carefully ai-ranged plan, as Fairchild noticed horsemen on the road ahead and behind him when the shots were fired. Had John Fairchild instead of James been present another tuurder might have been added to the list, as the üregonians are bitter in their hatred of John, the old man, and other Caiiforniaus.
