"Canst thou bind the sweet influence of Pleiades, or loose the bands of Orion? Canst thou bring forth Mazzaroth in his season? Or canst thou guide Arcturus with his sons? Knowest thou the ordinances of heaven?"—Job.

Phenomena that arrive with the days, months, seasons, centuries, are accompanied by events of corresponding significance in the human world, for everything is related to everything else.

In 1858 a new party came into being, headed by the prophet from the wilderness, who was as much a phenomenon in the human world as the comet of that year was in the starry heavens—an apparition first observed by the Florentine astronomer, Donati. Some scientific authorities give Donati's comet an orbit of two thousand, others three thousand years. Its advent was as unexpected as was the advent of Lincoln. Its immense orbit, the splendour of its train, its seeming close proximity to the earth, the presentiments which it inspired in millions of the people, corresponded with the sentiments and sensations inspired by the phenomenal progress of Lincoln, the avatar of democratic freedom and justice. The following description is taken from "The Valley of Shadows":—

"After a long period of cloudy weather the sky cleared, and when darkness closed in the night came with a revelation. Never had such a night been witnessed by living man, for a great comet hung suspended in the shimmering vault like an immense silver arrow dominating the world and all the constellations. An unparalleled radiance illumined the prairie, the atmosphere vibrated with a strange, mysterious glow, and as the eye looked upward it seemed as if the earth was moving slowly towards the stars.

"The sky resembled a phantasmagoria seen from the summit of some far and fabulous Eden. The Milky Way spread across the zenith like a confluence of celestial altars flecked with myriads of gleaming tapers, and countless orbs rose out of the luminous veil like fleecy spires tipped with the blaze of opal and sapphire.

"The great stellar clusters appeared as beacons on the shores of infinite worlds, and night was the window from which the soul looked out on eternity."

Such was the celestial apparition that ushered in the new party which was to support Abraham Lincoln and send him to the White House.

In all vital phenomena there is periodicity. The barometer comes to its minimum height for the day between four and five in the evening; again, it is at its maximum height between eight and ten in the morning and between eight and ten in the evening. The two first of these periods is when the electric tension is at its minimum; at its maximum during the two latter periods. The basic unit of the lunar day is twelve hours. An ordinary or solar day is two days, and an ordinary week is two weeks. This hebdomadal or heptal cycle governs, either in its multiple or submultiple, an immense number of phenomena in animal life in which the number seven has a prominent place. A Mr. Hay, of Edinburgh, writing some sixty years ago, says:

"There is harmony of numbers in all nature—in the force of gravity, in the planetary movements, in the laws of heat, light, electricity and chemical affinity, in the forms of animals and plants, in the perceptions of the mind. Indeed, the direction of natural and physical science is towards a generalisation which shall express the fundamental laws of all by one simple numerical ratio. The mysticism of Pythagoras was vague only to the unlettered. It was a system of philosophy founded on existing mathematics which comprised more of the philosophy of numbers than our present."

Philosophical students of human nature have taken note of the danger professional and business men encounter when they extend their mental activities beyond the hour of four p.m. (by the sun). Thousands fail because of their ignorance of the fundamental laws governing all things physical. The morning hours up to ten a.m. are just as dangerous for many who are highly susceptible to the electric tension which occurs up to that hour. The feeling that prevails from four to eight in the afternoon is one of mental or physical fatigue, that in the morning one of irritability.

Lincoln was not immune from natural law. On one occasion, at five p.m., he was suddenly informed of the defeat of the Northern Forces, and it was feared by those who were present that he would fall to the ground. Mr. C. C. Coffin sprang forward to assist the President, who, however, succeeded in returning to the White House unaided.

Nature creates the natural, man the unnatural. Solomon declared: "To everything there is a season, and a time to every purpose."
