The Nephites in the land of Zarahemla early appreciated the strategic importance of holding possession of the narrow neck of land--the isthmus which connected the southland with the northland. They perceived that if hard-pressed by their Lamanite enemies, who out-numbered them to the extent of two for one, [10] the narrow neck of land afforded them a means of escape into the great land northward, while by fortifying the narrow passage their enemies, however numerous, could be held in check, while they themselves would have a whole continent behind them in which to expand. The Lamanites also saw the strategic importance of this isthmus, and in some of the great wars in the last half of the century immediately preceding the coming of the Messiah, they sought to possess it, and the Nephites as strenuously sought to prevent them from taking possession of it. [11] The first extensive migration of Nephites into the north continent occurred in the thirty-seventh and thirty-eighth year of the reign of the Nephite judges, a period which corresponds to fifty-five B. C. That year five thousand four hundred men, together with their wives and children, left the land of Zarahemla for the northland. That same year one Hagoth, spoken of in Nephite annals as a "curious man," established ship-building yards on the borders of the land Bountiful, on the west side of the isthmus connecting the two continents. Here he constructed a number of large vessels, in which great bodies of immigrants were carried northward, to found new homes. Two of Hagoth's vessels that started northward never returned, nor was anything ever afterwards heard of them. The Nephites believed them to have been wrecked at sea. It is supposed by some that these Nephite vessels may have drifted westward and that their occupants may have peopled some of the islands of the Pacific. About ten years after this first great migration northward the movement of population in that direction received a fresh impetus; for great numbers went from Zarahemla and extended their journey farther northward than heretofore. Contentions in the land of Zarahemla--contentions born of pride, seem to have been responsible in some way for this movement. Doubtless in the old centers of Nephite civilization the possession of large wealth led to class distinctions, and inequalities, most distasteful to a people who from the first arrival of their fathers on the promised land had been taught to look upon each other as equals. Migration from the land where distinctions based upon the possession of wealth, and the pride it fosters, presented itself perhaps as the easiest solution of the difficulty, and hence the impetus to the northward movement in this year 46 B. C. [12] The Nephite historian, Mormon, in speaking of conditions that obtained about this time, gives one of those rare glimpses of Nephite civilization that I consider of sufficient importance to quote at length:
