Some leading mine-owners of Ceutral City, Dolorado, took the trouble to get up a plendid exhibition of their rich ores at Paris, last summer, which compared so fa-orably with the minerals from other counrics on exhibition there, that the French Hovernment authorized one of the Profeaors of the Evole des Mines, Simonin, to isit the Rocky Mountains, and report the esults—which have beeu looked for in the Journal des Mines, but have not yet apeared. Simonin arrived at Central City m company with J. P. Whitney, a Bostohian mining operator, who has identified himself with that section, ahont the time or oon after the close of the Exposition last “all, and was received with great distinction by the miners and capitalists there, who have heen forced to look for every assistance hat practical and scientific experts, from hatever source, can afford them in the reluction of their mixed aud difficult ores of ‘old and ailver contaiuing large percentizes of the anlphides of copper aud lead.

Spaulding’s Patent Movable Saw Teeth. It is now more than thirty years since movable teeth have been inserted into small sawa, such as are used for sawing shingles, clapboards, ete. But it is only quite recently the true principle for their proper insertion has been discovered and practiced. For many years after the employment of movable teeth was attempted in large saws, ao much difficulty was enconntered from the cracking of the plate, that their use was but very limited, and many who had cssayed to uso them were compelled to drop them and go back to the solid teeth, on account of the impossibility of making the platea stand. The plates always gave way in the augles of the sockets . SPAULDING’S PATENT made for receiving the teeth ; and when a crack was once commenced, it was sure to gradually increase, and progress toward the center of tho plate until the saw become worthless. After a while the practice grew up of drilling a small hole at the extreme end of tho crack, which often served to stay the progress of the same. From this idea, Mr. N. W. Spaulding, of this city, conceived the idea of making the sockets on circular lines, After a little experimenting, sufficieut to prove the value of that mode of setting teeth, Mr. 8. patented his new method of setting teeth. The claims npon this patent, which hears date Sept. 10th, 1861—re-issued April 21st, 1863— read as follows: What I claim as new, and desire to secure by letters patent, is:—Ist, Forming the recesses or sockets, in saws or saw-plates for detachable or movable teeth on circnlar lines, suhstautially as and for the purposes herein set forth 2d. In combination with sockets or recesses formed in saws or saw-plates, as lerein recited, I claim tecth having their base or bottom parts formed round, or on circular lines as described. The illustration herewith given clearly exhibits the form of Spaulding’s Movable Teeth, and of the socket into which they are inserted. A represents the saw-plate, B the adjustable tooth, CG C the socket, D the tooth when fastened into the plate, E the rivet for holding the same firmly in its place, F ahows a small key-seat, placed iu the bottom of the tooth for the purpose of allowing a key to be driven under to raise it out of the slot. G G ahows the flauges of the tooth and edges of the saw. These teeth are made and inserted by Mr. Spaulding as a private husiness of his own, hut carried on in counection with, aud in the Pacific Saw Com pany’s Factory, at Nos. 17 and 19 Fremont street, in this city, of which company he is amember, <A full description of these works was published on Thursday. Mr. Spanlding employs some twelve hands in Buchanan's Patent Horse Power Fastener. This newly patented device for confining horse power, for threshing machinea and other purposes, ia meeting with much success, aud saves a great deal of time and money to farmers in the hurrying aeaaon of harvestiug. *“19U9ISEY 19MK0g-03I0H yuazwg s,ususyong MOVABLE SAW TEETH. his especial business of making and inserting artificial teeth. The process is nearly all dono by machinery, and hy the most skilled workmen which the couutry can produce. The introduction of the circular socket formed a new era in the saw husiness—rendering the use of movable teeth perfectly practicable, and greatly reduced the running costs of saws. The successful introduction of these teeth, together with some other hut less important improvements, has within a few years nearly doubled the capacity of any given saw for work. A aaw once cutting 10,000 fcet of lumber per day, can now be made to cut fully 20,000 feet. The feed was then 1% inch, when it is now 3-inch. Among the advantages of movable teeth, is the fact that they cau he made to carry more feed, cut easier and with the use of The cut shows how the frame of the thresher is fasteued hy means of rods at the side, and keys at the end, to the frame that ia staked firmly to the ground by means of the four iron pins. When firmly driven into the hard, dry adobe soil of California, these pins are easily and quickly drawn without the use of any tool other than a stick of hard wood or crow-bar, as shown at the upper left hand corner of the engraving. The washer, which operates loosely on the piu, is raised sufficient to admit the end of the lever, and the upward pressure on one aide causes it to clasp and raise the pin. Upon raising tho lever again, the washer falls from its own gravity, taking afresh hold, and thus the procesa is re peated. Mr. Walter Buchanan, Solano county, is the inventor and patentee, to whom letters should be addressed for infornation. Tnmrensr Yrutp or WueEat.—The papers published in San Joaquin County aro loud in their praises of certain sectiona of that county, which have produced upwards of 40 bushels of wheat, and 85 hushela of barley to the acre. There is on exhibition at the Fair, some heads of Chili club wheat, raised in ios Augeles County this season, which yielded 80 bushels to the acre; on the same farm, the barley yield was nearly 100 bushels to the acre. While the yield in San Joaquin has been immense—extraordinary as compared to that in other countries—it is nothing extra for California. Such is the nature of the soil and climate of this highly favored State, that many fields of wheat, less power, and he kept in order at half the} prico of fixed teeth. In addition to the foregoing illustrations, ; we refer the reader to the last column of this paper, which contains further illustrations of various saws maunfactured by the . Pacific Saw Company.
