Swamp whortleberry, vaccinium corymbosum ral charcoal or coke. Peat, which is found in great abundance and easily procured in many of the European countries, where other fuels are scarce, is there much more highly appreciated than it is in the United States. Its qualities have there been thoroughly investigated, and various methods have been contrived for im- E roving its adaptation to the uses for which it fitted. (See PEAT.) As a fuel, this mate- rial is much used for domestic purposes in the countries where it abounds, and it is applied both in the raw state and charred to manu- facturing operations. In the neighborhood of Oarolinen-Htitte, near Aichthal, in Styria, suc- cessful attempts have been made to smelt iron with it in its raw state, mixed with wood ; while the charcoal obtained by charring it has long been successfully applied to the same pur- pose in Bohemia, Bavaria, France, Russia, and other countries. When freshly cut, peat con- tains from 80 to 90 per cent, of water, which by drying is commonly reduced to about 25 per cent. When well dried, the heating power of good peat is about the same as that of wood, and about half that of bituminous coal. The following analyses by Sir Robert Kane and Dr. W. K. Sullivan are of peat dried at 220 F. The proportions are calculated after deducting the ash. The percentage of the mineral ingre- dients varies in good peat from 1 to 5 ; some qualities contain much more, even 33 per cent., but such are worthless for fuel. VARIETIES. Carbon. Hydro- gen.

The methods introduced in western Europe of utilizing the dust of min- eral coals and of charcoal are nearly all based upon the principle of making these substance cohere by thoroughly incorporating them with tar or pitch, and then exposing the compound, when moulded into blocks, in some cases to a current of air to dry them, and in others high temperature in vessels serving the pui
