It is reasonable to suppose that the mind that constructed man was fully competent to undertake and complete the being to suit the purpose for which he was designed. After giving him physical perfection in every limb, organ, or part of his body, it is reasonable to suppose, that at that time, he gave him all the mental powers needed for all purposes during the life of his race, and with that perfection in the physical, it is supposable he approached very nearly to intellectual perfection. He was a mathematician, not by collegiate process, but by native ability. He did not have to take a course in a university to study chemistry, because of the fact that he was a chemist when he was born. Possibly he could speak or understand all languages spoken by the human tongue, from the powers of his mind, which occupied a pure and healthy physique. In a word he was well made and fully endowed with all the physical and mental forces necessary to the whole journey of his life. Now a question arises: "When did he begin to degenerate physically and mentally?" Let us reason some on this line, which seems to be a rather solid foundation, and as history is young itself, and has imperfectly recorded only such events as have transpired during a few centuries, with records imperfectly preserved. EVIDENCES OF PREHISTORIC MAN. We see evidences all along the journey of prehistoric man's life, though the being and his bones have been mostly obliterated; we see close to his bony remains the stone axe, the flint-dart. We find acres of ground in many places close to mounds and caves, with countless millions of slivers that have been scaled from flints and formed to suit war purposes; while the many bones that are found in caves, heaps and piles, indicate that many thousands fell in mortal combat then and there. Possibly they were old in the skilled arts of war at that day. Their great and powerful men, who should have been parents of the coming generations, were slain and destroyed and the conquered became the captives and slaves of the more powerful, with all opportunities for mental development suppressed. Other nations and tribes willingly entered the bloody fields of battle, with nothing to report but the death of the best physically formed men, and leaving the propagation of the race or races to be kept up by those who were left behind as unqualified to go into battle, for lack of strength of either body or mind. This process of destroying the mentally and physically great has been kept up to the limits of our history's record. We have to go to schools about one-half of our time in order to cultivate and stimulate our mental energies sufficiently well, that we may follow the ordinary business pursuits of life. MENTAL DWARFAGE.
