 ORE SHIPPING.
 But little ore has been shipped from the Mansfield property and that only for testing purposes. The only figures available are on a shipment of about 1000 pounds to the Copper Queen smelter at Douglas. The sulphide character of the ore is such that no smelting charges were made; but after deducting freight and other incident als the net return on the, shipment was $2s6.44, for which the proofs may be seen by anyone interested. It is only fair to say that this was selected ore. Other shipments will be ma ie as soon as possible, also for testing purposes in tonnage quantity. It cannot be conceived. however, that it is the purpose of the company to ship ores in large quantity unless some un- expectedly large and rich deposits should be encountered. Unless th ores are of exceptionally high grade the haul a short one and the railroad almost at the mine dump. the busi- ness of copper producing is rarely a shipping proposition. Rich shipping ores that will stand expensive hand ling are generally in small quantity and the Mansfield has planned for large operations which will necessi:ate reduction plant nearby. For ton of Mansfield ore that vii. warrant shipment there are available a hun dred tons that could be handled to a splendid profit with a large plant close at hand. The Mansfield, aside from the rich spots here and there, found in most mines, is a large low-grade proposition one that augurs we'll for big profits with the handling of a large tonnage. Thsre is no doubt of the availability of this tonnage ilj but little doubt of its constantly in- creasing av rage value as development proceeds. as we'll as the increasing of the available tonnage.
 REDUCTION WORKS.
 A reduction plant 5s therefore a question for early conside, ation. The various workings are not vet suffi- ciently opened up for economical stoping. but with the presen. rate of progress they soon will be and it is likely some further tests will bc re- |quired to fully determine the charac- ter of the plant needed. A concenira- tor however will be a necessity wher- h. rnIa l.. To-. project of constructing T plant at the mine involves a fuel haul from the railroad as well as the return hlri of the product and other necessary freighting. There is an ample supply of wood on the property for mining purposes, the wood being secured Of Mexican contra ctors at s3.50 per cord, but that is a matte enurely separate from shelter fuel.
 It would seem to be most feasible to construct smel.ing and concen- trating plant a= Crittenden, three miles above Patagonia, on :he rail road. and the company acting on this idea has secured recently ar ample tract of land at Critten,len including an ideal smelter site. It has been estimated that the expense of a tram way from the mine for trar sporting the ores to Critt andsh. a distance of six miles, will cost about S30,00O or S5,000 a mile. That would settle al transportation difficulties and the pro- posed line of the tramway offers TO endorsements in construction. A double cable trarway could he easily operated by a stationary engine. II might be advisable to build the con lcentrator at the mine. hut quite likely both plants would be better at the railroad. By the time a 200 ton con centrator and 1GD-ton shelter caIl be built, it is a reasonable expectation that the mine would be fully able "a furnish sufficient ores to keep :he.n busy.

 DOING THINGS.
 If the reader has carefully followed the foregoing description of camp construction, equipment. developmen, of the claims. road building. installa- tion of machinery. etc. he must have realized by this time that a vast amount of work has been accomplish ed on the Mansfield property. and that it's development is in a well-advanced stage. With all the preliminaries ac- complished. the Sweet workings ap- preaching the stoping stage and vari- ous other workings not far behind in development, few more months should make available a large tonnage of ore And all this has been accom- plished since the 22nd day of last Au- gust. when the first tap of work was done on the property. That a wonder full amount of work has been dore in a brief space of time is evident to any one who makes an inspection of the property. That the work has been well done is also apparent and go far as can be seen every stroke has been put in to good advantage. The criticism might be offered by some that the
