[By Stephen L Richards, who was an LDS apostle and First Counselor in the First Presidency]

In substantiation of this view the writer calls attention to the well-known distinct primary divisions of the human race now on the earth, namely, the Caucasian, the Mongolian, and the Negroid; and that these branches of mankind differ not only in bodily appearance but especially in mental qualities. The black skin of the Negro is not simply an excessive sunburn; no Caucasian becomes black, however long he may reside in tropical climates; and no Negro born and bred in temperate climates ever becomes white. Intermarriage between members of these great racial divisions are possible, but the progeny are usually feeble, not long-lived, and of poor physical quality; and no permanent self-propagating, homogeneous races can be generated by such intermarriages. Hence these different classes of mankind amount in effect to a difference in species. The Caucasian branch is characterized by a very superior inventive and originative power. All the great inventions of the human race and conquest of the natural energies of nature have come to the world through them. The important tools, instruments for land cultivation and food production, the invention of the steam engine, electric motor, telegraph, telephone, railway, steamship, magnetic compass, sewing machine, and an infinity of other inventions have originated through the Caucasian race. The yellow and black races have contributed nothing to this work. They have added nothing to new scientific or philosophical ideas.

Then as regards language, there is a very important difference. The words in the Caucasian language are highly inflected or modulated to express cases, tenses, moods, genders, and sexes, and have special adaptation for conveying abstract ideas or philosophical or scientific concepts. But the Mongolians have none of these qualities. Their words are made by putting together monosyllables. Their language has no proper grammar. The Negro languages are also simple and not adapted for conveying any but the simplest ideas and thoughts.
