In addition to, but closely associated with, the economic causes of Anglo-Saxon expansion was the realization in England of the need for prompt action in putting a limit to the growing domains of the King of Spain. In the century which had elapsed since Columbus opened a new world to the peoples of Europe, this monarch had seized the richest part of the great prize, and was still reaching forward to the north and to the south. Unless England took advantage of the present opportunity, the vast American continents might be closed to her forever. Anglo-Saxon civilization in that case might well remain permanently cooped up in the little island that had seen its inception, while the Spanish language and Spanish institutions expanded to embrace the garden spots of the world.[1-10] There were still other motives for this great movement. The English felt the prime necessity of discovering and controlling a new route to the East, they wished to expand the influence of the Anglican church and convert the Indians, they hoped to seize and fortify strategic points in America which would aid them in their struggles with the Spaniards. But these things, important as they were, paled beside the pressing necessity of national expansion, of rehabilitating English industrial life, restoring the merchant marine and securing economic independence. Thus, when Captain Newport returned in 1607 to report that the colony of Virginia had been safely launched, many Englishmen were aroused to a high pitch of hope and expectation. Now at last a province had been secured which could supply the raw materials which England so greatly needed. The active supporters of the undertaking were lavish in their promises. Virginia would yield better and cheaper timber for shipping than Prussia or Poland, she would furnish potash in abundance, and since wood could there be had for the cutting, her copper and iron ore could be smelted on the spot. Wine could be made there, as excellent as that of the Canaries, they boasted, while it was hoped soon to manufacture silk rivalling in fineness that of Persia or of Turkey. The waters of the colony were full of "Sturgion, Caviare and new land fish of the best," her fields could produce hemp for cordage and flax for linen. As for pitch, tar, turpentine and boards, there was a certainty of a rich return.[1-11] In February 1608, the Council of Virginia wrote to the corporation of Plymouth: "The staple and certain Comodities we have are Soap-ashes, pitch, tar, dyes of sundry sorts and rich values, timber for all uses, fishing for sturgeon and divers other sorts ... making of Glass and Iron, and no improbable hope of richer mines."[1-12]
