consist of a tube or tubes, or wire encased in wood or iron pipes, through which signals shall be communicated by electricity, compressed air or other pneumatic devices, or by ringing a bell. When compressed air or other pneumatic devices are used for signaling, provision must be made to prevent signal from repeating or reversing. The following signals shall be used at mines where signals are required:

From the bottom to the top: One ring or whistle shall signify to hoist coal or the empty cage, and also to stop either when in motion. Two rings or whistles shall signify to lower cage.

Three rings or whistles shall signify that men are coming up or going down; when return signal is received from the engineer the men shall get on the cage and the proper signal to hoist or lower shall be given.

Four rings or whistles shall signify to hoist slowly, implying danger.

Five rings or whistles shall signify accident in the mine and a call for a stretcher.

Six rings or whistles shall signify hold cage perfectly still until signaled otherwise.

From top to bottom, one ring or whistle shall signify: All ready, get on cage.

Two rings or whistles shall signify: Send away empty cage.

Provided, that the operator of any mine may, with the consent of the inspector, add to this code of signals in his discretion. The code of signals in use at any mine shall be conspicuously posted at the top and at the bottom of the shaft, and the engine room at some point in front of the engineer when standing at his post.

GAUGE.] (f) Every boiler shall be provided with a glass water gauge and not less than three try cocks and also a steam gauge, except that where two or more boilers are equipped with a steam drum properly connected with the boilers to indicate the steam pressure and without any valves between said boilers and the steam drum, the steam gauge may be placed in said steam drum; and other steam gauge shall be attached to the steam pipe in the engine house, each to be placed in such a position that the engineer and the fireman can readily see what pressure is being carried. Such steam gauges shall be kept in good order, and adjusted and be tested as often, at least, as every six months.

SAFETY VALVES.] (g) Every boiler shall be provided with a safety valve with weights or springs properly adjusted, except that where two or more boilers are equipped with a steam drum properly connected with the boilers to indicate the steam pressure and without any valves between said boilers and the steam drum, the safety valves may be placed in said steam drum.

INSPECTION OF BOILERS.] (h) All boilers used in generating steam in and about coal mines or sinking shafts shall be kept in good order, and the operator of every coal mine where steam boilers are in use shall have said boilers thoroughly examined and inspected by a competent boilermaker or other qualified person, not an employee of said operator, as often as once in every six months, and oftener if the mine inspector shall so require in writing, and the result of every such inspection shall be reported on suitable blanks to said mine inspector.

RUN-AROUND AT BOTTOM.] (i) At every underground landing where men enter or leave the cage and where men must pass from one side of the cage to the other there shall be a safe passageway, free from obstruction and dry as possible, around the shaft not less than three feet wide for the use of men only; and animals or cars shall not be taken through such passageway while men are passing or desirous of passing through such passageway.

REFUGE PLACE ON SHAFT BOTTOM.] (j) A refuge place or places for men coming out at the close of the day's work shall be provided off the main bottom of cageroom in shaft mines, at a place or places and of such size as shall be approved by the State mine inspector. Such place or places shall be not more than 400 feet from the shaft where men are hoisted, and shall be kept free from loose material. When leaving such refuge places to be hoisted out, the men shall be governed by the rules of the mine.

OBSTRUCTION IN SHAFT.] (k) No accumulation of ice or obstructions of any kind shall be permitted in any shaft in which men are hoisted or lowered; nor shall any dangerous gases or steam be discharged into said shaft in such quantities or at such times as to interfere with the safe passage of men. All surface or other water which flows therein shall be conducted by rings or otherwise to receptacles provided for the same in such manner as to prevent water from falling upon men while passing into or out of the mine or while in the discharge of their duties about the shaft bottom.

INSPECTION.] (1) All shafts by which men enter or leave the mine, and the passageways leading thereto, or to the works of a contiguous mine used as an escapement shaft shall be carefully examined throughout at least once each week that the mine is operating and the date and findings of such an examination entered promptly in the books kept at the mine for that purpose. A daily visit to the bottom of all such escapement shafts shall be made by the mine examiner, and if obstructions to the free passage of men are found, their location and nature shall be stated in such report. Such obstructions shall be promptly removed.

§ 15. REFUGE PLACES-POWER HAULAGE ROADS.] (a) On all singletrack haulage roads, where hauling is done by machinery, which roads. the persons employed in the mine must use while performing their work or travel on foot to and from their work, there shall be places of refuge on one side not less than 3 feet in depth from the side of the car, and not less than 4 feet long and 5 feet in height and not more than 60 feet apart. On all such roads constructed after the passage of this Act, the refuge places shall be placed on the opposite side from the electric power wire. On rope-haulage roads, means of signaling shall be established between the haulage engineer and all points on the road. A conspicuous light shall be carried on the front, and a gong, conspicuous red light or white signal board on the rear of every trip or train of pit cars moved by machinery.

REFUGE PLACES-MULE ROADS.] (b) On all haulage roads on which the haulage is done by draft animals, whereon men are obliged to be in the performance of their duties or have to pass to and from their work, there shall be places of refuge not less than 21/2 feet in width from the

side of the car, and not less than 4 feet long and 5 feet in height and not more than 60 feet apart.

ROOM-NECKS AS REFUGE PLACES.] (c) Refuge places shall not be required in entries on which room-necks at regular intervals not exceeding 60 feet furnish the required refuge places.

Keeping refugE PLACES CLEAR.] (d) All places of refuge must be kept clear of obstructions and no material shall be stored nor allowed to accumulate therein. They shall also be whitewashed not less than once in six months.

GOB ON HAULAGE ROADS.] (e) One side of all haulage roads shall be kept clear of refuse or materials, except timbering, unless the rib or timbering on such side shall be 22 feet or more from the rail. But in such case materials or refuse shall not be permitted within 21% feet of the rail.

§ 21. CERTIFICATED MINE EXAMINERS.] (a) A certificated mine examiner shall be required at all coal mines. There shall be one or more additional certificated mine examiners whenever required in writing by the State mine inspectors when the conditions are such as to make the employment of such additional mine examiners necessary.

(b) It shall be the duty of the mine examiner:

1. To examine the underground workings of the mine within eight hours preceding the time the day shift goes on duty, every day upon which the mine is to be operated, excepting that when in the judgment of the State mine inspector expressed in writing to the coal operator, a mine generates explosive gas in dangerous quantities, a State mine inspector shall require the mine to be examined for gas in such manner and at such shorter intervals than eight hours before the time the day shift goes on duty every day upon which the mine is to be operated, as may be necessary to ensure the safety of the men working in such mine. 2. When in the performance of his duties, to carry with him a safety lamp in proper order and condition and a rod or bar for sounding

the roof.

3. To see that the air current is traveling in its proper course and in proper quantity; and to measure with an anemometer the amount of air passing in the last cross-cut or break-through of each pair of entries, or in the last room of each division in long-wall mines, and at all other points where he may deem it necessary; and to note the result of such measurements in the mine examiner's book kept for that purpose.

4. To inspect all places where men are required in the performance of their duties to pass or to work, and to observe whether there are any recent falls or dangerous roof or accumulations of gas or dangerous conditions in rooms or roadways; and to examine especially all roadways leading to escapement shafts or other openings for the safe exit of men to the surface, the edges and accessible parts of recent falls and old. gobs and air-courses.

5. As evidence of his examination of said rooms and roadways, to inscribe in some suitable place on the walls of each, not on the face of the coal, with chalk, the month and the day of the month of his visit.

6. When working places are discovered in which there are recent falls or dangerous roof or dangerous conditions, to place a conspicuous mark or sign thereat as notice to all men to keep out; and in case of

accumulation of gas, to place at least two conspicuous obstructions across the roadway not less than twenty feet apart, one of which shall be outside the last open cross-cut.

7. Upon completing his examination, to make a daily record of the same in a book kept for that purpose, for the information of the company, the inspector and all other persons interested; and this record shall be made each morning before the miners are permitted to enter the mine.

8. To take into his possession the entrance checks of all men whose working places have been shown by his examination and record to be dangerous, and to give such entrance checks to the mine manager before the men are permitted to enter the mine in the morning.

§ 25. DUTY OF INSPECTOR.] (a) Any loss of life or personal injury in or about any coal mine shall be reported without delay by the person having charge of said mine to the State mine inspector of the district in which the mine is located, and the said inspector, in case of injury, if he deem necessary from the facts reported, and in all cases of loss of life, shall go immediately to the scene of said accident and render every possible assistance to those in need.

Every operator of a coal mine shall make or cause to be made and preserve for the information of the State mine inspector, upon uniform blanks furnished by said inspector, a record of all deaths and all injuries sustained by any of his employees in the pursuance of their regular occupations.

CORONER'S INQUEST.] (b) If any person is killed in or about a mine, the operator shall also notify the coroner of the county, or in his absence or inability to act, any justice of the peace of said county, who shall hold an inquest concerning the cause of such death. The State mine inspector may question or cross-question any witness testifying at the inquest.

INVESTIGATION BY INSPECTOR.] (c) The State mine inspector shall make a personal investigation as to the nature and cause of all serious accidents in mines under his supervision. He shall make a record of the circumstances attending the same, as developed by the coroner's inquest, and by his own personal investigation, which record shall be preserved in the files of his office, and a copy thereof filed with the State Mining Board within thirty days from the conclusion of such investigation, and such report shall thereupon become part of the records of such board. To enable him to make such investigation he shall have power to compel the attendance of witnesses and to administer oaths or affirmations to them, and the cost of such investigations shall be paid by the county in which such accident has occurred.

Any person having charge or custody of the records, files, documents, reports and proceedings of the State Mining Board provided to be made, filed or kept under the provisions of the laws of Illinois, in case of serious accident shall furnish to any person or persons interested, a certified copy thereof upon application, and upon the payment or tender of fees at such rates as are now paid in this State to the clerks of circuit courts in counties of the second class for certified copies of records, and refusal to furnish such copies shall constitute a misdemeanor.
