Notices to Gorrespondcuts, Puvrontc Inruvences have been in the ascendant in the minds of our townsfolk for a few days past. The high spring tide of Thursday was pronounced an earthquake, wave heralding dreadful occurrences elsewhere, and the smoke from the burning redwoods on the northerly and seaward side of Tamelpais, which has heen rolling calmly over the ocean and bay, owing to an nousually light atmosphere, was associated with Kilauea, and with the fires which are reported hy telegraph to he devastating the forests of Oregon and Washington. Between Cowlitzand the junction of the Willamette, an area of 200 square miles is reported burning. The dreadful earthquake of the 13th of Augustin South America no doubt laid the foundation for the many surmises which were credulously circulated. It is stated that no earthquake has occurred during the present century whose effects have been so disastrous in that country. The earthquake wave seemed to originate near the equator and to travel southward, so faras South Amcrica was concerned. In Ecuador and Peru there were two waves discernahle, which crossed each other. Transit instruments were thrown out of level at the same time at the Sandwich Islands. Itis surmised that the sources of disturbance are probably connected with the volcanoes of Agualougo and Cayambes. On the 14th of August an earthquake wave was observed at Los Angeles. Minine In Ex Dorapo anp AMADOR Countres.—We have received additional communications from our traveling correspondent, describing the mines and mining operations at Diamond Springs, Sugar Loaf, Nashville, Placerville and Pleasant Valley, in El Dorado County, and at Amador City, Spring Hill, Sutter Creek, Jackson and Pine Grove, etc., in Amador County; all of which will appear in due scason. see Ice Maxinc.—A gentleman wishes to know if any parties in San Francisco are prepared to furnish machinery for produciug ice economically in quantity—say 1,000 poundsin twelve hours. Any person who will give written information to this office on this subject, stating cost of machinery, amount of power and other necessary expenses required, will confer a favor. Information from manufacturers ahout it are solicited. Pracy’s New Engine Regulator. With great pleasuro we chroniclo suhstantial improvements wrought out from time to time, by the steady working, practical mechanics, who seem more deserving of success than inventors who stumble into good fortunes by making accideutal improvements entirely out of the line of their practice. It is with these feelings that we herewith present an illustration of a recent inveution by Geo. T. Pracy, of No. 109 Mission street, in this city, of an improved governor for steam engines. ho engraviug shows the regulator with the arms extended, as if in rapid revolution. The balls are confined by jointed arms, hinged at the top and bottom, and having = knuckle-joint in the center. The slack is taken up and the valve of the regulator opened by theaction of gutta percha springs, situated in the cylinders or pots on the right and left—operating by the plungers which are connected hy lugs to the lower portion of the arms. This regulator assumes somewhat the appearance of the Pickering Governor, but it is much simpler, having no spring bands to he nicely tempered aud adjusted, and liable to hreakage and repair. It is suited to any rate of revolutiou. The speed of an engine can be quickly adjusted by turning set-screws on the hottom of the cylinders which operate on the rubher springs. While this regulator can he made as cheaply as the ordinary governor, the inventor, one of our hest mechanics, who has had one in operation for sometime, confidently claims it to be the best regulator in use. An ordinary mechanic with a common blacksmith forge could repair any of its parts in case of damage hy accident. The force of the spriugs produce constant hearing on thé various joiuts, preventing any loose motion of the same. It is more neat and cleanly than the common regulator. Mr. Pracy has applied for letters patent, and already sold several of his governors. He invites the examination of the one in operation at his shop, hy all parties interested. We regret that this California invention was not iu season for exhihition at the Fair. Patent Cigarette Rollers. Although an experienced hand is supposed to make a handsome cigarette in comparatively quick time yet when we come to apply the little piece of mechanism here represented, the old seems like a slow process of manufactnre. The Hazman Excelsior Cigaretto Roller is being introduced with favor in the Eastern States, and is certainly a novel instrument. The rollers are about *<-inch in diameter, and 3%4 inches in length. Its principles of operation are well illustrated by the following directions for use: Hold the machine in a horizontal position, the hinge-bar below, the rollers above, resting on the palms of the forefingers, and the thumbs heing applied on the inner, the forefingers on the outer roller. Open the frame, soas to form of the india rmbber hand a trough, or receiver, upon which: the requisite quantity of tobacco—about three pinches—is equally spread and slightly pressed, so as not to prevent the rollers from joining. Close the machine and turn the rollers a few times; the thumbs on theinner roller geutly operating downward, and the forefingers on the outer roller upward, assisting the motion evenly. Then insert one of Hazman’s Patent Cigarette Wrappers into the gap hetween the upper roller and tohacco, having the prepared or adhesive surface next the tobacco; close and rotate, slightly pressing the rollers together, hut using uo force, during the process. The wrapper having nearly disappeared, wet its margin—a few more rotations will complete the cigarette. The wrappers used with these rollers are of the natural color of tobacco, and are so prepared as to destroy the bad taste and influence possessed by paper commonly used for wrappers. For further information in regard to this invention, address A. H. Hale, box 17, San Francisco P. O. + Tum BEnerits that were given during the last week of the Mechanics’ Fair, resulted in substantial aid, as follows: Yor the Roman Catholic Orphan Asylum on Monday, $648.50; for the Ladies’ Protection and Relief Society on Tuesday, $631; for the Protestant Orphan Asylum on Wednesday, $1242.75 ; for the Female Hospital and 8. F. Benevolent Asylum joiutly on Thursday, $700 ; and for the Mechanics’ Institute Library on Friday, $690.25. Se Centra Canirornra.—Mr. Doolittle has published a new map of Central California, embracing the counties of Butte, Yuba, Sierra, Nevada, Placer, El Dorado, and Sacramento. Royat Guocraruican Socrety.—Bishop Staley, of Honolulu, read a paper before the Royal Geographical Society, recently, on the ‘‘ Geography of Hawaii, and the Reecnt Volcanic Eruptions,” in which he stated that according to the census of 1867, the native populatiou had continued to decrease as much as 8,300 during tho past seven years, the total being now 58,765, while the whites had increased 400, uumhering at present 4,194. Industriul girls’ hoarding schools were heing established, to check the evil at its source. The whole archipelago had heen lifted out of the ocean by voleanic agency, which began in the northwest islands, and gradually extended to its present seat of activity on the southeastern island of Hawaii, dying out hehind. Coral heds were found at an elevation of 4,000 feet ahove the sea. At the recent eruption, mud streams hurst up through the soil, and buried villages and ranches, The column of vapor which issued from Kilauea was visible at a distance of 120 miles, and computed to be eight miles in hight. Enguish TEACHERS AT Panris,—Pecuniary encouragement was offered hy the Science and Art Department of the Committee of Council on Education in Great Britain, to all government instructors who would visit the Paris Exposition, and write reports upon their own technological specialties. very hranch of the useful arts and sciences has heen trented upon by persons whose husiness it is to communicate their information to others. Amongst the teachers named in the Science Directory, Mr. Gihsone is mentioned as writing to the Chemical News on the chemistry of the exhihition; Mr. Mayer, to the Glasgow Jownal, on Metallurgical and Chemical Processes and Products; Mr. Bolam, on Navigation; Mr. Davidson, to the Journal of the Society of Arts, etc. en Tur “Roran Furnace” has commenced operations at Jefferson City, Montana, upon ores from the Alta Montana lead. It was run continuously for fifteen hours, at the end of which time 500 pounds of rich metal or crude silver bullion was taken from it. An assay of this metal shows it to contain silver to the value of $474 in coin per ton, or at the rate of ahout $100 to the ton of ore. The first run was made upon selected rock, hut it was made under some disadvantages. The operations are superintended by Mr. Fred. Holaus, the same gentleman who was connected with the Essler furnace at Argenta last winter. Government CHarces oN TELEGRAPHY. The ‘Electric Telegraphic Bill” which has just been passed hy the British Parliament practically abolishes all private telegraphy enterprise in the United Kingdom, and places the business into the hands of the Post-office Department. Cheapness, universality, and uniformity of telegraphing, are the advantages promised. The goyernmeut having come to an understanding with the telegraphic companies, no opposition was made to the bill. Douhts of want of efficiency are raised against the plan.
