The colonies attempted by Frobisher and Gilbert were to serve as relays in the work of exploration for a sea passage to the Pacific and the search for mines, but they mark strongly the influence of the Spanish example on English projects. Ralegh was a lifelong opponent in peace and war of Spanish intrigue and aggression, and his efforts to plant colonies in the virgin land were suggested by a knowledge of the almost exhaustless treasure that flowed into Spanish coffers from America. The opportune capture of a Spanish carack bound homeward from Mexico with letters describing the wealth of Mexican mines brought the support of English merchants to Ralegh's undertaking. Imbued with the same spirit, Ralegh's governor wrote from Roanoke Island in 1585 that his colony would be a means of deliverance from the domination of Spain, "whose strength doth altogether grow from the mines of her treasure." In the perilous isolation of the little company on Roanoke Island, Lane assures himself that God will feed his men by means of ravens rather than suffer their "enemies the papists" "to triumph at the overthrow of this most Christian action." The home-staying English of that age were spurred to colony-planting by three main motives--cupidity, patriotic feeling, and religious zeal--and all of these were provoked by emulation and jealousy of Spain. II. [Sidenote: Delusions in colony-planting.] The prolonged movement for a colonial establishment, which extended over the latter half of the reign of Elizabeth and almost the whole of the reign of James I, was kept alive by delusions. The ultimate ends for which colonies were proposed and planted in the last quarter of the sixteenth and the first quarter of the seventeenth century were none of them attained. The movable passage through North America to the Pacific was still leading explorers a merry dance when the first Jamestown emigrants sailed in 1606, and gold mines of comminuted mica, of iron pyrites, of Indian mineral paints, and of pure fable were potent attractions for some time after. The gradual increase of geographical knowledge caused the "South Sea" to take shelter in the unknown region behind the mountains, and the gold mines reported by Indians and discovered by sanguine prospectors were somehow lost in the interminable forests. In this exigency the first colony must have perished for want of support if new hopes as illusive as the old had not moved the English people to avert such a calamity.
