No race has stronger characteristics, bodily or mental, than that powerful, obstinate, fiery, pious, humorous, honest, industrious, hard-headed, intelligent, thoughtful and reasoning people, the Scotch-Irish. The vigorous qualities of the Scotch-Irish have left broad and deep traces upon the history of the United States. As if with some hereditary instinct, they settled along the great Allegheny ridge, principally from Pennsylvania to Georgia, in the fertile valleys and broader expanses of level land on either side, especially to the westward. In the healthy and genial air of these regions, renowned for the handsomest breed of men and women in the world, the Scotch-Irish acted out with thorough freedom, all the vigorous and often violent impulses of their nature. They were pioneers, Indian-fighters, politicians, theologians; and they were as polemic in everything else as in theology. Jackson and Calhoun were of this blood. An observant traveller in Tennessee described to the writer the interest with which he found in that state literally hundreds of forms and faces with traits so like the lean erect figure, high narrow head, stiff black hair, and stern features of the fighting old President, that they might have been his brothers. Many of our eminent Presbyterian theologians like the late Dr. Wilson, of Cincinnati, have been Scotch-Irish too, and with their spiritual weapons they have waged many a controversy as unyielding, as stern and as unsparing as the battle in which Jackson beat down Calhoun by showing him a halter, or as that brutal knife fight in which he and Thomas H. Benton nearly cut each other's lives out. Horace Greeley is of this Scotch-Irish race, and after a rule which physiologists well know to be not very uncommon, he presents a direct reverse of many of its traits, more especially its physical ones. Instead of a lean, erect person, dry hard muscles, a high narrow head, coarse stiff black hair, and a stern look, he tends to be fat, is shambling and bowed over in carrying himself, thinskinned and smooth and fair as a baby, with a wide, long, yet rounded head, silky-fine almost white hair, and a habitually meek sort of smile, which however must not be trusted to as an index of the mind within. Meek as he looks, no man living is readier with a strong sharp answer. Non-resistant as he is physically, there is not a more uncompromising an opponent and intense combatant in these United States. Mentally, he shows a predominance of Scotch-Irish blood modified by certain traits which reveal themselves in his readiness to receive new theories of life.
