character of the lower coal seam, have been kept reasonably well up to the requirements of the mining law.

I measured a total quantity of air, of 41,000 cubic feet per minute, in circulation which was being well distributed to the face of the workings in both mines. The drainage of the lower mine was excellent, and of the upper one reasonably good.

Some improvements have been made in these mines during the year, such as shortening, grading and draining the hauling roads, especially has this been the case in the Upper or No. 3 mine.

Star Xos. 5 and 6.-These two mines are in splendid condition both in regard to ventilation and drainage. No. 5 mine is opened on the Lower Freeport coal seam, and No. 6 on the Upper Freeport coal

A Clark ventilating fan six feet in diameter has been erected at No. 5 mine, and a ventilating furnace seven feet wide and six feet high has been built during the year. The total volume of air per minute produced from both of these fans was 37,000 cubic feet, which . Was being well distributed to the face of the workings.

I new haulage system has been arranged for bringing forward the coal from these two mines to the top of the old inclined plane. The mines are situated a distance of 3,800 feet apart with a ridge or hill midway between the mouth of the mines and the top of the plane, consequently, the haulage plant proper is placed on the top of the ridge. The empty mine wagons are brought up to the top of the hill from the top of the plane by the rope and engine, and are dropped from the top of the ridge to the mines by gravity, the train of cars taking the hauling rope with it. Then the loaded cars are hauled from the mines in the valley to top of the ridge and the trip of wagons dropped over the hill to the top of the inclined plane by gravity, the trip taking the rope with it. This haulage system works admirably.

Mines Situated at Reynoldsville, Jefferson County. There are five mines situated in this region, one of which (Big Soldier Run) is the largest in Western Pennsylvania. These mines have not been operated nearly to their full capacity and have experienced much broken time from dull trade during the year.

Hamilton and Sherwood. These mines were not in operation at the time of my last visit to this region, but it it previous visit IIamilton was in a very good condition both as regards ventilation and drainage, while Sherwood at that time could not be so favorably reported as far as the ventilation was concerned. A large "fault” had been encountered in this mine cutting off most of the coal seam in nearly all directions, thereby disarranging the plan of working. and owing to the uncertainty of advancing the workings any farther,

the air current had not been conveyed as near to the face of the entries as it should have been; but the officials promised to have this defect remedied at once.

Big Soldier Run.—This is a very extensive mine having about 750 men employed therein. A large tonnage (3,000 tons) is produced daily. One-half of it is produced by mining machines and the other half by pick miners.

The mine is in splendid condition both in regard to ventilation and drainage. I measured a volume of air in circulation of about 98,000 cubic feet per minute which was being well conveyed to all parts of the mine.

Sprague Mine.--I measured 26,000 cubic feet of air per minute in circulation in the workings of the "new" mine and 26,000 in the "old" mine, making a total volume in both places of 52,000 cubic feet. This volume was conveyed well up to the head of all the entries in three or four separate “splits.” The drainage was reasonably good, consequently the general condition of the mine was well up to the requirements of the law.

Henry Bros. Mine.-I measured 10,000 cubic feet of air in circulation which was conveyed to the face of all the workings of the mine. This mine is about up to the requirements of the law in every particular, it is therefore in splendid condition.

Mines Situated in Lawrence and Beaver Counties.

There are sixteen mines situated in this division of the district, and they have been operated reasonably steadily during the year with one exception, the Darlington, a new mine which was in operation forty-two days only. Ten of these mines averaged a run of 236 days each, four of them averaged 183 days and the Rock Point mine which supplies the locomotives, on the Pittsburgh and Western railroad with coal had a run of 310 days. This is a better average time for these mines than they have experienced for the few previous years.

Cannelton Mine, which is a small concern, was not found in very good condition. The coal property upon which this mine has been opened is an old abandoned one which had been worked over many Vears ago, and it had in a sense been honeycombed leaving nothing for the present company to work but small blocks of coal and the pillars remaining from the old works. Under such conditions it is almost impossible to carry out a regular plan of work, however the ventilation and drainage has been considerably improved since my visit.

Butts Cannel Shaft.—This mine was in splendid condition in every particular and up to the requirements of the mining law. I measured about 20,600 cubic feet of air per minute in circulation well carried to the face of the works.

Sterling Mine was in very good condition both in regard to ventilation and drainage. I measured 21,000 cubic feet of air in circulation fairly well distributed throughout all of the workings.

State Line Mine was in splendid condition. All the requirements of the mining law were being complied with. I measured 16,500 cubic feet of air in circulation which was well distributed throughout the entire workings.

Beaver Falls and Clayton Mines were not in operation during my last visit to that region, but I found them in fair condition at one of my previous visits.

Baker.-There are two main openings to this mine. In what is known as the "old" mine there are only a few miners working in drawing the entry pillars. This part of the workings was in very fair condition. The greater number of the miners are working in the "new" opening. While this "new" opening was fairly well ventilated, yet the total volume of air was not quite sufficient. The workings as a whole were in reasonably good condition. I measured a total volume of air for both mines of 9,500 cubic feet per minute.

Beaver Mine when last examined was in splendid condition both in regard to ventilation and drainage.

Mining machines have been introduced into this mine during the year to do part of the mining. Whether they will prove a financial success or not has not yet been fully determined, although the manager has faith that they will prove satisfactory.

The Clinton Mine when last examined was in very good condition both in regard to ventilation and drainage. I measured about 7,700 cubic feet of air in circulation which was being well conveyed to the face of the workings.

In the Excelsior Mine I measured 12,600 cubic feet of air which was being well distributed throughout all of the workings. The mine is in good condition generally.

Mehard Mine.- This is a comparatively new mine and at the time of my last visit the company was making preparations to put in a new furnace with which to ventilate it properly. The ventilating shaft had already been sunk. The mine was not sufficiently venti lated at time of my visit, but since then this defect I am informed has been remedied.

Rock Point Mine is in very good condition both in regard to ventilation and drainage. I measured 10,800 cubic feet of air in circulation which was being well conducted to the face of the workings.

The Thompson Run Mine was well ventilated and reasonably well drained. I found 9,900 cubic feet of air in circulation which was well distributed throughout the different parts of the mine.

The Penn Mine was not in operation at time of my last visit, but at a previous examination it was not in as good a condition as it might have been had the small details been carefully attended to.

Connessing Mine, is a new operation situated on the Pittsburgh and Western railroad and operated by the Connessing Coal Company with J. Wylie, superintendent, and J. E. Brown, mine foreman. It is a drift opening and was found to be in very good condition. Since my visit a “second” opening has been provided.

Alines Situated Along the West Pennsylvania Railroad in West

moreland and Armstrong Counties. There were eleven mines in operation in this division of the district during the year. The average time worked at these was from one-half to three-fourths. The Apollo, Foster and Fairbank mines have remained idle since last year.

Gilpin and Haddon mines were in splendid condition in every particular at date of last examination and the requirements of the mining law were well complied with.

I measured in the Gilpin mine about 25,000 cubic feet of air in circulation with a sufficient volume of it conveyed to the face of the workings. Eight thousand one hundred cubic feet of air was being produced in the Haddon mine which was well distributed throughout the whole workings.

Avonmore mine at time of last visit was in splendid condition. There was a sufficient quantity of air in circulation throughout all parts of the mine, as I measured about 37,800 cubic feet per minute. A new ventilating furnace has been built in what is known as the "dip” workings, the dimensions of which is 7 feet wide, 7. feet high, and the arch is 18 feet long. The workings of this mine are separated into two divisions and for each division there is a separate ventilating furnace.

At Pine Run mine I found 14,300 cubic feet of air in circulation which was being well conducted to all parts of the mine. The mine was in very good condition both in regard to ventilation and drainage.

Bagdad No. 3.—This mine will soon be finished. One division of the works where the greater number of the miners were working was in splendid condition while the old part of the workings were not in very good order. I measured 6,000 cubic feet of air in circulation.

Leechburg mine No. 4 has been in operation reasonably steadily during the year. At the time of my last visit I found it in excellent

23--10--95

condition both in regard to ventilation and drainage. I found in circulation in all parts of the mine 21,940 cubic feet of air per minute.

In the Beal mine I found an ample volume of air at the outlet but the distribution of it was somewhat defective. The drainage was Very good. The total volume of air produced was about 10,800 cubic feet per minute.

The Kirkpatrick mine at the date of my last visit was found to be in very good condition generally. Volume of air in circulation, 9,400 cubic feet.

At the West Penn mine although there was a sufficient quantity of air being produced, it was nearly all lost before it reached the face of the entries through excessive leakage at the brattice cloth doors which had been hung at the mouth of the various rooms. Where such material is used for doors and where the mine is being worked by the single entry plan it is an impossibility to maintain efficient ventilation.

Bagdad mine No. 2 was in splendid condition. The ventilation was sufficient and the drainage very good. A small ventilating furnace has been built at this inine during the year.

Blackstone mine was in excellent condition and well up to the requirements of the mining law. The ventilation and drainage were very good. The quantity of air circulating throughout all parts of the mine was 13,900 cubic feet per minute.

Mines in Mercer and Butler Counties Situated on the Pittsburgh,

Shenango and Lake Erie Railroad. There are seventeen mines located in this division of the district, ten of which worked over one-half time, and the others from onefourth to one-half time. This shortage in working time at these mines was caused by lack of trade. No labor troubles occurred here during the year.

Enterprise mine was in excellent condition at time of last visit. The ventilation and drainage were good.

ITallville mine has not been in operation for the last few months, but was in fair condition when last examined.

Keister mine was in operation about 5.3 days during the year, but when last examined it was found in good condition.

The Spears mine has not been in operation much more than onefourth time during the year. This mine was not in very good condition at the time of my last examination. The air current was weak at the face of the works and the hauling roads were not in very good condition. These conditions seem to be the natural result where mines are operated a few days one month and remain idle the next.
