HUNGERFCRD'S IMPROVED CONCENTRATOR. Wo givo annexed a very correct pictorial illustration of “ Hungerford’s Improved Concentrator.” ‘Lhe improveineut consists inainly in an addition of a cireular trough, outsido of the periphery of the ordinary Prater Concentrator, into which the sulphurets are discharged from tho main body of the machine, and from which they are again discharged into any convenient vessel, through openings shown upon the right hand of figure 1, and which can be kept either closed or open. Both discharges are produced by the action of the machine itself. The working of the Prater concentrator is too well known to our readers, and has beer FIG.

The present improvenent by Mr. Hungerford, is quite distinctly shown in the perspeetive view of the machine, as seen in figure 1. ‘he prinFIG. 2—-SECTIONAL VIEW OF CONCENTRATOR. ciple of the action of the machine, and of tbe new improvement, may be observed in the Sectional view, us given iu figure 2, Another important feature is the tneans by which the oscillatory motion is imparted to the pan.

A emall opening will be seen through the inner wall of the pan, through which the sulphurets readily pass from the main hody ol the machine to the circular trough, 3, 3, already described, as constituting Mr. Iungerford’e principal improvement. These openings arc flaced at intervals of a few inches, entirely around the circumference of the pan. It will be observed that tho sulphurets in the trough, 3, 3, are maintained at tbe same elevation as the snlphurets and overlying sand in the body of the pan. {t will be further observed that by no possible means can tbe sand in the latter pass to tbe former in sucb quantity as to form any considerable percentage of the amount saved. The advantages of thie improved pan are continuous action, requiring ho attention except to remove the receiving vessels as fast as they are filled from tbe openings shown on the right of figure 2, simplicity in construction, and durability and cheapness of cost. ‘hese pans aro made at the Miners’ Foundry, on First street, where they may be scen in constant operation, and where the inventor, Mr. Hungerford, can also be seen and consulted.

Our exports tothe Hast consist almost entirely of articles of domestic produce, such as hides, wool, wine, barley, ores, quicksilver, etc. Tbe export of hides shows a steady gain during the time specified. Thesame remark will hold good of the yool export, up to the time we commenced manufacturing our own woolens. The increase in. tbe value of our exports to New York and Boston, has progressed quite steadily from $1,113,500 in 1856, to $6,159,100 in 1865, Over two-thirds of the whole amount of gain has been made during the past five years. . Our commerce with foreign countries has heen Tbe cause of the decline with the former hag of courso heen due to the unhappy political state of that country, which must at longest be but tempornry. The mining excitemeuts in the latter country will account for tbe fluetuatious there. The present anuual atnount of our exports to British Columbia are about $1,250,000 in value; to South America, about $500,000, and to all other places aboat $520,000 — making a grand total of nearly $8,500,000. For the present year they will be largely increased by the enorinous grnin crops, which are now almost ready for the sickle, and which, if shipping is found to take them away, will add several millions to the aggregate value of the shipments of 1866-7. <a ++ Mrnica, Torocrarny or Cairornia.— We have received a copy of Dr. Logan’e “ Report on the Medical Topography and Epidemics of Calilornia ; extracted trom the transactions of the American Medical Association.” It isa coutinuation of a previous similar report, by the same author, on the diseases aud meteorology of the Sacramento Valley, from 1849 to 1858.
