No. 11. SIXTH BITUMINOUS DISTRICT. 423Barnesboi'o.—lu and about this place there are ehneu mines, theSevenhirgest number clustered about any one point in the district.tf them are machine mines, four using compressed air and theother three elec(rici(y. In only one is the coal hauled by machinery,an electric motor. Two are ventilated by fans, the othersby furnaces. It is certainly a great mistake to use furnaces wherethe power for machine ventilation is available, as 500 ])ounds ofcoal additional burned under the boilers would jModuce more air witha fan than two tons of coal consumed in a fuinace. Thus there wouldbe a very considerable saving in a year, without taking into accountthe labor necessary to attend the furnace. The sanitary conditionof the above mentioned mines is quite satisfactory, exce])t in the''Delta'' mine, which has grown bej'ond the capacity of the furnaceand should now have a fan.Amsbry.—There is one mine at this place, and another on the samebranch of the railroad, at Dysart. Tlie latter is not a very largeworking. It is ventilated by a furnace, and wlien examined lastwas not in very satisfactory condition eithei- as to ventilation ordrainage. The former is ventilated by a fan and when last visitedwas found to be in good condition.Spangler Mines.—All of the three mines located here are ventilatedby furnaces, which, being large, give satisfaction, as the mines arecomparatively small. In the largest of the three workings not morethan 00 men are employed. Ventilation and drainage are good inboth.Elmora.—One of the two mines here opens on the P>, or Miller vein,and the other on the 1), or Moshannon bed, both being operated by thesame linn. A\mtilation and diainage are in fair condition, bothmines using furnaces.Hastings.—Two of the six operations are ventilated by fans andfour by furnaces. The latter are comparativel}^ snuill workings,none of them employing more than 50 men; cousequeatly furnace ventilationis adequate. All are i)ick mines except one, where the coalis dug by machines driven by compressed air. The condition of themines is very satisfactory on the whole, as those in charge lookafter them well and take particular care that each one shall havegood drainage.Frugality.—Two mines are operated at this place. One is ventilatedby both fan and furnace the mining being done by compressedair. The other is a pick mine and is ventilated by a furnace only. Inboth the sanitary condition is satisfactory in every respect.Vintondale.—Fans ventilate the two collieries in Ihis place and inboth, the hauling is done by machinery, electric; motor being used inone and rope haulage in the other. Electiicity is the power used
