In 16GG, when Cakobau conquered the tribes in that district, some men of the town of Quali were killed by people from a neigh bouring place. Tn 1873 their friends°of other towns saw their chance, and sud denly attacked the unsuspecting people, killing 57, and sending their bodies to be eaten, and as a token of their triumph, to all the towns with whom they were in alliance. These people are the Kai Colos or mountaineers, who inhabit the hills of the Upper Jttewa, and are still heathens. Cakobau, with 1200 men, has himself gone to punish them. By the time he gets into the hills his force will number 4000 to 5000, and ought to be successful. But a force equally large was defeated by these mountaineers in IS6S, and the settlers of he Upper Rewa are anxious lest there should be a similar mishap, which would place them temporarily in peril. Cako bau's men are, however, so much better supplied with arms and ammunition than thuy wore eight years ago that defeat is unlikely. Success would be attended with groat results, and kad to the final suppression of the mountaineers, and the security of the whole of the island, which is the largest, the most important, and the most populous in the group. The massacre at Ivorowaiwai, reported by the last mail was, it seems, not exag gerated. There were about 160 killed, and the details of the massacre are given with horrible minuteness in the papers, which express the disgust felt by the set tlers. The white officers who were in command did their best to stop it, and were in some instances successful, but the savages chcy led had become unmanage able. Such .scenes are inevitable where native is pitted against native, and nothing but the sternest need is likely to cause their employment by the Government again. The remedy will l»e sought in the employment of a small drilled force under control from habits of discipline, and un attended by the hordes of irregulars who committed the barbarities on the present occasion. Mr Renn'e, formerly of Dunedin, and a Mr Vaughan have had a dispute with the natives in the neighbourhood of the former's plantation. They had settled on a piece of land belonging to Mr Rennie, who went with Mr Vaughan to order them away.
