Suppose that the shores of this great land were fringed, as those of tropical Australia are now, with belts of mangroves, which would extend landwards on the one side, and be buried beneath littoral deposits on the other side, as depression went on; and great beds of mangrove lignite might accumulate over the sinking land.

The production of iron ore is reduced by 19 per cent., of anthracite by 14 per cent., of lignite by 70 per cent.

It is eaten out into holes and furrows, plainly by the gnawing of the waves; and on it lie, in many places, large rolled flints out of chalk which has been destroyed, beds of shore-shingle, beds of oysters lying as they grew, fresh or brackish water-shells standing as they lived, bits of lignite (fossil wood half turned to coal), and (as in Katesgrove pits at Reading) leaves of trees.

You find gradations between them and beds of lignite, or wood coal; then gradations between lignite and common or bituminous coal; and then gradations between common coal and culm, or anthracite, such as is found in South Wales.

Now is it not plain that if such trees as that sunk, their bark would be turned into lignite, and at last into coal, while their insides would be silted up with mud and sand?

And he tells us that wood can become lignite, or wood-coal, by parting with its oxygen, in the shape of carbonic acid gas, or choke-damp; and then common or bituminous coal, by parting with its hydrogen, chiefly in the form of carburetted hydrogenthe gas with which we light our streets.

There is lignite and other coaly matter enough in the rocks to have burnt like coal, if it had once been ignited; and the cause of ignition may be, as Mr. Wall suggests, the decomposition of pyrites, of which also there is enough around.

That the heat did not come from below, as volcanic heat would have done, is proved by the fact that the lignite beds underneath the porcellanite are unburnt.

(2) It has also been considered as the result of the more or less complete decomposition of plants under the influence of heat and dampness, which has led them to pass successively through the following principal stages: peat, lignite, bituminous coal, anthracite.

Anthracite and bituminous coal would have belonged especially to primary times, lignites to secondary and tertiary times, and peat to our own epoch, without the peat ever being able to become lignites or the latter coal.

Anthracite and bituminous coal would have belonged especially to primary times, lignites to secondary and tertiary times, and peat to our own epoch, without the peat ever being able to become lignites or the latter coal.

Peat 5.63 57.03 29.67 2.09 5.58 Lignite 5.59 70.49 17.2 1.73 49.1 4.99 1.2 Bitumin.

The quantity of oxygen and hydrogen that they contain is greater, and seems to bring them near the lignites.

If, then, lignites have not become soft coal, and if the latter has not become anthracite, it is not that time was wanting, but climatic conditions and environment.

Le lignite stratiforme qu'on exploite au Mont-Yorck, a 1000 pieds au-dessus du niveau de la mer, et dont la presence ajoute aux motifs qui portent

There are outcroppings of lignite at numerous points on the island, and in the vicinity of Mt. Halcon is found the finest marble yet discovered in this part of the world.

"There was a good old lignite fire blazin' away 'n the station.

The different fuels in common use for cooking purposes are hard wood, soft wood, charcoal, anthracite coal, bituminous coal, coke, lignite, kerosene oil, gasoline, and gas.

Bituminous coal ignites readily, burns with considerable flame and smoke, and gives a much less intense heat than anthracite, Lignite, or brown coal, is much less valuable as fuel.

The sedimentary rock of sandstone, shales, and marl, not only showed veins of ignitible lignite, but it was pierced by the trap which had been shot up from earth's flaming recesses.

JET, a hard, black, bituminous lignite, capable of an excellent polish and easily carved, hence useful for trinkets and ornaments, which have been made of it from very early times; is found in France, Spain, and Saxony, but the best supplies come from Whitby, Yorkshire.

It might better be characterized as a highly carbonized lignite, likely to contain much sulphur as iron pyrites, rendering them apt to spontaneous combustion and injurious to boiler plates.

Nevertheless, he says, when pyrites seams are avoided and the lignite is properly handled, it forms a valuable fuel, especially for local consumption.

Every quarter the owners have to pay a halfpenny per ton on the output, if it be bituminous coal; and a farthing a ton, if it be lignite.
