The presenceof the sulphuric acid and sulphates is due to the large percentage offerric sulphate contained in the coal-mine effluent. Being an im-stable compound, it breaks up when acted upon by the oxygen of theair, parting with the iron which settles on the rocks in the bed, form-ing a coating of ferric hydroxide which gives to the entire stream avery rusty appearance. The Xorth Branch, between Westernport and Keyser, West Vir-ginia, has little fall. Xear the latter town it passes over an old mill-dam.

The pollutionfrom this source alone is estimated at 1,200 gallons a day. Besidesthis, a variety of chemicals are discharged into the water, togetherwith much coloring matter used in dyeing the wool. On New Creek6 miles above Keyser is situated a tannei-y o%vned by the United StatesLeather Company with a capacity of GO hides a day.

There are two smallsawmills on this stream, but the sawdust discharged by them isinsignificant in amount. The disc
