As has been said, Arus was a practical man. He dwelt among the Picts and found much that an intelligent man could do to aid humanity, even when that humanity was cloaked in tiger-skins and wore necklaces of human teeth. Like all priests of Mitra, he was instructed in many things. He found that there were vast deposits of iron ore in the Pictish hills, and he taught the natives to mine, smelt and work it into implements--agricultural implements, as he fondly believed. He instituted other reforms, but these were the most important things he did: he instilled in Gorm a desire to see the civilized lands of the world; he taught the Picts how to work in iron; and he established contact between them and the civilized world. At the chiefs request he conducted him and some of his warriors through the Bossonian marches, where the honest villagers stared in amazement, into the glittering outer world. Arus no doubt thought that he was making converts right and left, because the Picts listened to him, and refrained from smiting him with their copper axes. But the Pict was little calculated to seriously regard teachings which bade him forgive his enemy and abandon the warpath for the ways of honest drudgery. It has been said that he lacked artistic sense; his whole nature led to war and slaughter. When the priest talked of the glories of the civilized nations, his dark-skinned listeners were intent, not on the ideals of his religion, but on the loot which he unconsciously described in the narration of rich cities and shining lands. When he told how Mitra aided certain kings to overcome their enemies, they paid scant heed to the miracles of Mitra, but they hung on the description of battle-lines, mounted knights, and maneuvers of archers and spearmen. They harkened with keen dark eyes and inscrutable countenances, and they went their ways without comment, and heeded with flattering intentness his instructions as to the working of iron, and kindred arts. Before his coming they had filched steel weapons and armor from the Bossonians and Zingarans, or had hammered out their own crude arms from copper and bronze. Now a new world opened to them, and the clang of sledges re-echoed throughout the land. And Gorm, by virtue of this new craft, began to assert his dominance over other clans, partly by war, partly by craft and diplomacy, in which latter art he excelled all other barbarians.
