From CALIFORNIA there have been three arrivals since our last, bringing an aggregate of $1,700,000 in gold, and between 700 and 800 passengers. Our dates are up to the 1st of February. The intelligence of most importance is that of desperate hostilities between the Indians and the whites. The former seem to have determined upon a war of extermination, which of course meets with prompt retaliation; and the ultimate issue can be no matter of uncertainty. Seventy-two miners were attacked by surprise in a gulch near Rattlesnake Creek, and massacred to a man. A petition for aid was dispatched to the Executive of the State, and a force of 200 men ordered out. In the instructions to the commander, directions are given studiously to avoid any act calculated unnecessarily to exasperate the Indians. A daring attack was made on the 9th of January, by a company of 40 or 50 Americans, upon an intrenched camp, manned by 400 or 500 Indians. The position was so strong that a dozen whites might have defended it against thousands. Of the Indians 44 were killed, and the _rancheria_ fired. Many of the aged and children were burned to death. Of the Americans two were killed, and five or six wounded. It is reported that all the Indians from Oregon to the Colorado are leagued together, and have sworn eternal hostility to the white race. The product of gold continues to be great. The report of the new gold bluffs, mentioned in our last Number, is confirmed; but the access to them is so difficult that they will not probably be soon available. They are situated near the mouth of the Klamath River, about thirty miles north of Trinidad. The approach to them by land is over a plain of sand, into which the traveler sinks ankle-deep at every step. The bluffs stretch along some five or six miles, and present a perpendicular front to the ocean of from 100 to 400 feet in height. In ordinary weather the beach at the foot is from 20 to 50 feet in width, composed of a mixture of gray and black sand, the latter containing the gold in scales so fine that they can not be separated by the ordinary process of washing; so that resort must be had to chemical means. The beach changes with every tide, and sometimes no black, auriferous sand is to be seen on the surface. By digging down, it is found mixed with a gray sand, which largely predominates. The violence of the surf renders landing in boats impracticable. Several tons of goods were landed from a steamer dispatched thither, by means of lines from the vessel to the shore. The Pacific Mining Company claim a large portion of the beach, and have made preparations for working the bluffs, and are sanguine of an extremely profitable result. Specimens of gold in quartz have been submitted to assay, which have proved very rich. Operations in the "dry diggings" have been much retarded by the absence of rain. Large quantities of sand have been thrown up, ready to take advantage of the earliest showers to wash it out.
