When such fine vegetable sediment is mixed, as is often the case, with clay, it becomes similar to the bituminous limestone and calcareo-bituminous shales of the coal-measures.
The place occupied by peats, lignites, and bituminous and anthracite coal in sedimentary grounds, and the organic structure that we find less and less distinct in measure as we pass from one of these combustibles to one more ancient, have given rise to the theory mentioned above, viz., that vegetable matter having, under the prolonged action of heat and moisture, experienced a greater and greater alteration, passed successively through the different states whose composition is indicated in the following table: H. C. O. N. Coke.
Dousterswivel accordingly set fire to a little pile of chips, touched and prepared with some bituminous substance to make them burn fiercely; and when the flame was at the highest, and lightened, with its shortlived glare, all the ruins around, the German flung in a handful of perfumes which produced a strong and pungent odour.
Thus it will appear, that it is no proper explanation of the formation of coal strata, to say that vegetable matter is the basis of those strata; for though, in vegetation, a substance proper for the formation of bituminous matter is produced, it remains to know by what means, from a vegetable body, this bituminous matter is produced, and how it comes to be diffused in that subtile state by which it may be uniformly mixed with the most impalpable earth in water.
At Porton, east of Truxillo, the same metamorphism which has changed the ridge of sandstone to a hard quartzite has also changed the ordinary bituminous coal into an anthracite, which is here vertical in position. The coals of Peru usually rise to more than 10,000 feet above the sea, and they are practically inaccessible.
But what I may term the "saccular matter" of the coal, which, either in its primary or in its degraded form, constitutes by far the greater part of all the bituminous coals I have examined, is certainly not mineral charcoal; nor is its structure that of any stem or leaf. Hence its real nature is, at first, by no means apparent, and has been the subject of much discussion.
The Indians have brought in specimens of bituminous coal said to have been obtained upon a stream discharging into Cumshewa Inlet, and they also report having seen a seam near Ninstints. Messrs Knight, Williams and Allen, practical coal miners of Nanaimo, prospected the islands for coal during the past summer, but made no locations. Copper.
The Clearfield Corporation, the Pennsylvania Coal and Coke Co., and the West Branch Coal Company are some of these. By their great holdings in other railroads traversing the soft coal regions, the Vanderbilts control about one-half of the bituminous coal supply in the Eastern, and most of the Middle-Western, States.
Now the currents of the ocean, however regular they may be for a certain period of time, and however long this period may be protracted, naturally change; and then the currents, which had given birth to one species of stratum in one place, will carry it to another; and the sediment which the moment before had formed a coal stratum, or a bed of that bituminous matter, may be succeeded either with the sediment of an argillaceous stratum, or covered over with a bed of sand, brought by the changed current of the sea.
It does not appear that the islands are much affected by earthquakes, although some have occasionally occurred that have done damage to the churches at Manila. The coal found in the Philippines is deemed of value; it has a strong resemblance to the bituminous coal of our own country, possesses a bright lustre, and appears very free from all woody texture when fractured.
