other and perhaps greater and richer ore bodies exist on the remainder of this large tract— the prospecting thus far having been confined to an area of less than 30 acres. The richness of the ore, the regularity of the formation, and the excellent management at this mine justifies the prediction that it will soon become one o. the largest producers of lead ore in the United States. The capital stock of the company is $350,000, divided into 3500 shares of $100 each, almost entirely owned in the city of St. Louis. The president is H. J. Cantwell ; sec. retary, C. S. Rogers, and the mine and works are under the charge of Arthar Thacher, a mining engineer of recognized ability, who is ably seconded by his assistant, R. D. O. Johnson.

THE DESLOGE CONSOLIDATED COMPANY, Of St. Francois county, of which Louis Fasz is president, and John M. Desloge superintendent, has its mine situated about one mile west of Desloge station, on the M. R. & B. T. R. R., from which point a switch has been laid to connect it with the works and mines.

The land on which this company is now operating was first prospected with the diamond drill by the Bogy Lead Mining Co. some years ago, but nothing of importance was done until the present company came into possessiðn. Since that time, however, the value of the property has been greatly increased by the expenditure of a large amount of money in prospecting and developing, and in the erection of the mill, furnaces and buildings with which the property is now equipped. The shaft now being worked is down to a depth of 325 feet, where a large body of ore is being stoped. Another body of ore is found in this shaft at a depth of 250 feet, which is being also quite extensively worked at that level.

The ore is the same as that found in all the large mines of this section, viz.: lead ore disseminated through the solid limestone layers. The ore taken out is crushed at the mouth of the shaft, and taken thence by railroad to the mill for concentration. Their mill has a capacity of 300 tons daily, but it is proposed to increase it to double that capacity in the near future. There are three reverberatory furnaces on the premises, which are, however, only capable of reducing to lead part of the concentrates, the balance being sold.

DOE RUN LEAD COMPANY.

The mines of this company are situated at Doe Run, St. Francois county, the southern terminus of the M. R. & B. T. R. R. The principal part of their ore is now coming from Flat river, where the company has just finished sinking a shaft 450 feet deep.

This is the deepest shaft ever sunk in St. Francois county (very probably the deepest in the State), but promises to make fine returns for the money invested, as it is said to be the richest in ore of any shaft ever sunk in the disseminated lead-ore belt.

The ground is very wet, and a great amount of time and money was expended in prosecuting the work. It was found necessary at 90 feet to make a sump by blasting away one side of the shaft and put in a pump to lift the water to the surface. At 250 feet another one had to be put in, in the same manner. These, with the sinking one, made three large pumps necessary to keep the water away from the workmen; and even since the completion of the shaft, large pumps must be used to keep the mine dry enough to operate.

This shaft is 10 or 12 miles from Doe Run, to which point the ore is taken for concentration. The concentrating plant at Doe Run is a fine one, being second only to that of the St. Joseph Lead Company in capacity and appointments, their smelting being done by the abovenamed company's furnaces at Herculaneum.

The mines produced this year 4500 tons of lead ore.

THE FLAT RIVER LEAD COMPANY.

The property of this company embraces 1295 acres of land, all in one body, and is located in the great Flat River district, St. Francois county, Missouri, 65 miles from St. Louis.

It is bounded on three sides by the following well-known proper: ties: St. Joseph Lead Company (new mines), Desloge Consolidated Lead Company, and the Doe Run Lead Company. Within the past three years a great deal of money has been expended here in prospecting and developing the property. A shaft bas been sunk to the depth of 332 feet, from which exceptionally fine ore has been taken from two different strata. Underlying the present workings, there still remains another stratum, rich in value, as has been shown by borings from the Diamond drill. It is estimated tbat these strata embrace a total of 20 feet of

very rich ore. The working plant is a complete one, embracing hoisting.engines, air compressor, air drills, boilers, shop, oil-house, powder magazine, reduction works with a capacity of 100 tons daily, smelter, saw. mill, water-pipe line, telephone line, office, boarding-house, twenty company houses, and the towns Leadville and Taylor Place.

The Mississippi River & Bonne Terre railway bisects this property, having the right of way through it for a distance of two miles, and have put in a spur, passenger and freight platform at the works.

THE LEADINGTON LEAD COMPANY, Of St. Francois county, is one of the new companies of this section, and for the first time reports a product from its mine. The mine proper is situated on part of what was formerly known as the “McKee mines,” and is about 2 miles distant (east) from Flat River station on the M. R. & B. T. R. R.

This company was first known as the “Farmington Prospecting and Mining Company," but in January, 1894, changed its name to that shown above. The company has a paid-up capital stock of $150,000, with F. Rodach president, and S. P. Reynolds superintendent.

The one shaft on the property is down to a depth of 350 feet, with cage and ladder ways. They have also a mill of 100 tons capacity, which has been running steadily since last May, and turning out a very fair quantity of lead ore, their report of only one month's work showing 187 tons of clean lead ore ready for market.

ST. JOSEPH LEAD COMPANY.

The St. Joseph Lead company, whose property is situated in and around Bonne Terre, St. Francois county, Mo., is by far the largest producer of lead in the State, and very probably the largest in the world. Its product this year is over 18,000 tons of lead ore, all of which was smelted at their works, and which realized more than three quarters of a million dollars.

The ore obtained is known as disseminated lead ore, and occurs in this mine about 225 feet below the surface. In some places in the mine immense bodies of this ore are found; one, in particular, is considerably over 100 feet thick, and of unknown extent laterally, several hundred feet of it having been explored in different directions.

Beside the mines immediately around the mill, the company is. working two other shafts, known as Nos. 7 and 8 respectively, the first being about one mile southwest of the mill; the other on what is known as the Crawley tract, situated on Flat river, about one mile east of the railroad station of that name, to which point it is connected by a switch. Both of these shafts promise rich returns.

The concentrating plant is one of the largest in the country, and all of the machinery used in driving its jigs, crushers, dynamos, etc., is of the best. Ten large Blake crushers, with an estimated capacity of 1000 tons of rock daily, are kept constantly working, to supply the jigs and tables by which the ore is separated from the rock. For a plant of this size very few workmen are to be seen, as from the time

the rock is put into the crushers to the time it is thrown over the dump, it is handled entirely by machinery.

The product of the concentrating plant is carried by the M. R. & B. T. railroad to the company's smelting works, which have recently been moved to Herculaneum, Mo.

MADISON COUNTY.

MINE LA MOTTE.

The mines of this company are situated in Madison county, on an old Spanish claim covering some 20,000 acres, and are at present owned by Mr. Rowland Hazard. These mines are by far the oldest in the State, having been worked continuously for more than 100 years, but continue to be one of its largest producers. It is the only one at present operated in Madison county, and seems to be the southern end of the great disseminated lead ore basin of St. Francois county.

The mine is very dry, and almost all its work done by hand, thus giving employment to about 180 miners. A new shaft has been sunk on the property this year, and about a mile of track built to connect it with the mill and furnaces.

All the ore is reduced to pig-lead, on the premises, and transported to market over the St. L., I. M. & S. Ry. Their product this year was 6,985,985 pounds of lead ore.

JEFFERSON COUNTY.

VALLE MINING COMPANY.

The Valle Mining Company's mines are situated on a line between St. Francois and Jefferson counties, and work is prosecuted in both, the company owning a large quantity of land.

This is the only mine in Southeast Missouri in which zinc is found in paying quantities, and their product of this ore is generally sold to the zinc smelters of Carondelet. Their lead ore is principally found in caves and in the clay near the surface, being, however, of very fine quality, and large masses of it are often found without a particle of gangue or rock attached. This product is smelted in Scotch hearth furnaces, and sent to market over the M. R. & B. T. R. R., which passes over the property. This year's output is 921 tons of zinc and 424 tons of lead ore.

ST. FRANCOIS COUNTY.

IRON.

As indicated in my last report, the iron mines of the State have suspended operation. Only one (the Iron Mountain) has reported this year, and that has since closed down; so that our iron-mining interests, which were once so large, are now at a stand-still. This is not on account of the exhaustion of the ore-bodies, but must be attri. buted to the low price of the metal and the great competition from other states.

FIRE-CLAY AND BUILDING-STONE.

In addition to the matter heretofore covered by reports from this office, I have this year given the results of some investigations regarding articles mined in the State, but not classed as minerals. These are the fire-clays and building-stones of our State, and also a very interestring article on tripoli, extracted from the “ Scientific American.”

The fire-clays form quite a product of Missouri. I have endeavored to collect as much information as possible regarding them, and the result is shown in a table appended with the others. This table I do not claim to be a full statement of the extent of that industry, but it is, at least, a beginning to a report which may be of value hereafter, The table shows that a product valued at $193,000 was taken out this year, and from this, I think it evident that the industry is worthy of some attention.

The result of investigations in building-stone quarries is also shown in a table. This table, like the one mentioned above, is the first of its kind published by this office, and like it, may not, and no doubt does not, include the full information that future reports may be made to show. This, however, is a great industry, and as our State can be made to produce enormously in this line, it should not be overlooked. The State abounds in all kinds of building-stone. The granite formations in the southeast cover an indefinite amount of territory; sandstone is found in various parts of the State ; and these, with the limestone with which the State is almost entirely underlaid, are all good building material. As the table shows, this branch of industry gave employment this year to 916 men, and shows also an output valued at nearly one-half million dollars.

Immediately following this will be found an article on "American Tripoli," by Mr. E. O. Hovey, published in a recent issue of the "Scientific American.” This industry has heretofore been comparatively
