^1 bearing districts, as follows : Argo smelting works, $2,500,000; Gilpin and 

 •Clear Creek Counties, $2,000,000; Boulder County, $1,000,000 ; Park County, 

 :$i,5oo,ooo; total, $7,000,000. The above does not include lead and copper 

 bullion. In 1881, there was shipped east from the Pueblos, via the Atchison, 

 Topeka & Santa Fe Railroad, gold and silver bullion, supplied from the districts 

 as follows: Lake County, $12,000,000; Gunnison, $1,000,000; San juan, $3,- 

 000,000; total $16,000,000. This does not include the gold production of Sum- 

 mit County, which at the present time has reached $1,000,000 a month, or $12,- 

 000,000 a year, every ounce of which goes east via the Pueblos, and, should we 

 add this to the figures of last year's shipment, we have a grand total of $28,000,000 

 of bullion (gold and silver) going east via the Pueblos yearly, while Denver can 

 boast of but one-quarter of that amount. To these figures may be added also at 

 least three millions, which come to the Pueblo smelters from Southern Colorado, 

 New Mexico, and Arizona, and are there converted into bullion and shipped 

 -east. 



Grant Smelter. — The completion of the Grant Lead Smelting Works at Den- 

 ver is near at hand. The main building, 240x100 feet, is all completed. In it are 

 eight furnaces, entirely finished, and which are calculated to average a total ca- 

 pacity of 300 tons a day. Adjoining the building on the west is the engine-house, 

 50 X 100 feet, also nearly finished, and containing a 200 horse-power engine, a 

 large boiler, and three mammoth blowers, besides a full equipment of pumps, 

 machinery for generating electricity for lighting the establishment, etc. The 

 -stack connecting with the dust-chambers will have a height of 165 feet. The re- 

 ceipt of ore has already begun, and two thousand tons will be on hand by the ist 

 December, when it is expected the works will begin operations. 



LAKE COUNTY. 



The Democrat gives Leadville's bullion product for the month of August as 

 follows : Three thousand six hundred and seventy tons of lead are reported to 

 have been produced and shipped by the Leadville smelters during the month of 

 August. This shipment contained 522,266 ounces of silver and 1,600 ounces of 

 gold. The total value of this shipment was within a few thousand dollars of 

 reaching a round million. This, of course, does not include the production of 

 the stamp mills and the ores shipped by ore-buyers and the Iron Silver and Rob- 

 ert E. Lee mines to Pueblo, Golden and other points. 



Garden City Lode. — Among the new discoveries of ore in paying quan- 

 tities, made during the past week, is that of this lode. This property is situated 

 in CaUfornia Gulch, at the foot of Iron Hill. A year or two ago, a shaft was 

 sunk on this property, to a depth of about 150 feet, -without disclosing ore in any 

 quantity. Recently the property was leased and active operations were com- 

 menced. At a depth of seventy feet, a drift was run to the southward, and a 

 fair body of ore was encountered. Drifts were then run in different directions, 

 all disclosing evidently the same ore-deposit. A level now driven to the east- 

 ward shows the ore for a distance of twenty feet, having a thickness of about
