Página 3 - My fire now burns with fuel, and my lamp is shining with the light of gas, derived from coal that has been buried for countless ages in the deep and dark recesses of the earth. We prepare our food, and maintain our forges and furnaces, and the power of our steam-engines, with the remains of plants of ancient forms and extinct species, which were swept from the earth ere the formation of the transition strata was completed. Our instruments of cutlery, the tools of our mechanics, and the countless...

Thus from the wreck of forests that waved upon the surface of the primeval lands, and from ferruginous mud that was lodged at the bottom of the primeval waters, we derive our chief supplies of coal and iron; those...

The trees of the primeval forests have not, like modern trees, undergone decay, yielding back their elements to the soil and atmosphere by which they had been nourished ; but, treasured up in subterranean storehouses, have been transformed into enduring beds of coal, which in these later ages have become to man the sources of heat, and light, and wealth. My fire now burns with fuel, and my lamp is shining with the light of gas, derived from coal that has been buried for countless ages...

Página 40 - ... bursting of them by the great expansion of the liquid oil which is caused by heat. These liquids expand in volume so much as one upon thirty by a rise of not more than 60° of temperature, or by such a change as from the ordinary low temperature of 40° to a blood heat ; the latter temperature may easily be exceeded in an engine-room.
Página 40 - A parcel of twenty-five newly-tarred coalsacks, which had been thrown upon the boiler, also obtained, it is supposed, some of the same oil. This oil appears to be the matter most liable to the possibility of spontaneous ignition, which was noticed near the spot where the fire commenced. But the sudden and powerful burst of flame from the store-room, which occurred at the very outset of the conflagration, suggests strongly the intervention of a volatile combustible, such as turpentine, although the...
Página 12 - No. 10, but from a different seam, remarkable for its great self-inflammability. Atmospheric oxidation of iron-pyrites is always a comparatively slow process, and consequently there must be much loss of heat. It is not, however, asserted that ironpyrites may not, when present in coal in considerable quantity, develop sufficient heat during its oxidation by atmospheric air to set the coal on fire. The coking qualities of some kinds of coal are completely destroyed by weathering. Some coals which when...
Página 27 - That the breakage of coal in its transport from the pit to the ship's hold, the shipment of pyritic coal in a wet condition, and, especially ventilation through the body of coal caryoes, conduce to spontaneous combustion, even though the coal may not be unfit for conveyance on long voyages.
Página 27 - That with a view to guard against explosion, free and continuous egress to the open air, independently of the hatchways, should be provided for the explosive gases by means of a system of surfave ventilation, which would be effective in all circumstances of weather.

The people of the latter island being roused from their slumbers, were greatly alarmed — and well they might be — at this unseasonable and extraordinary noise. Having repaired to the place where his head lay, and discovering that it was a gigantic being fast asleep, they held a consultation as to what was best to be done, and came at length to the resolution of killing him, if possible, before he awoke, lest he might eat them all up. With this intention, every man armed...
