There are two kinds of pitch: one, pure pitch, dead black, was loaded in the small cars, and the other, of a light brown colour, was carried off in dump-carts, drawn by mules. This black pitch forms the basis of all our asphalt pavements, and such a deposit must be worth millions to the concessionaires.
Now, when did this mighty process begin, and what internal force is at work producing this continual outpouring upon the earth’s surface?
At the farther end of the lake, women and young girls were busy gathering pieces of wood which were thrown up out of the pitch. I do not claim to understand this marvellous phenomenon. I would rather put the question to those of you who have access to the wisdom of libraries, and give you the privilege of bringing some light upon these strange manifestations of God’s unknowable. As I understand it, pitch is obtained from tar, boiled down, and tar is a black, viscous liquid obtained by the distillation of wood and coal, so this residuum which we see is the third step in one of Nature’s great caldrons; a process millions of years in forming, a process still in operation.
Is this wood which is continually coming to the surface of the lake an unused part of that vast primeval forest which was when time did not exist; when chaos was revolving into form? How long has it been wandering, and what force is it which sends it thus unharmed, save for the loss of bark, out again into the light?
Some very strange implements and tools, recognised as South American workmanship of a remote day, have come to the surface of this lake, and one theory for their appearance is, that they have been drawn under the Gulf of Paria, and up through the lake of La Brea by some unseen, but mighty power from the lake of pitch in Venezuela, of which this is supposed by some to be the outlet.
The wood, gathered by the women, is not petrified, but merely impregnated with the pitch, and has all its original qualities as when it first left the parent stem, with, however, the additional affinity for fire which its pitchy bath would naturally give.
