It was declared that baptism did not exempt slaves from bondage. As the reducing of negroes to slavery was justified on the ground that they were heathens, so the opinion prevailed among some that when they ceased to be heathens they were, by the very fact, released from slavery. In 1668, peace being restored, vessels were relieved from the necessity of anchoring under the forts. The war with the Dutch, unjustly commenced by the English, ended very disgracefully to them. A day of humiliation was appointed, and all persons were required to attend the parish churches, "with fasting and prayers, to implore God's mercy, and deprecate the evils justly impending over us." It was ordered that work-houses should be built in each county, for the instruction of poor children in spinning, weaving, and other useful occupations and trades. An act was passed for the "suppressing and restraint of the exhorbitant number of ordinaries and tippling houses." The Indians were required to bring in one hundred and forty-five wolves' heads annually, the reward for each head being one hundred pounds of tobacco and cask. To prevent fraud, the ears were cut off from the heads of the wolves.[268:A] The elective franchise was restricted, in 1670, to freeholders and housekeepers. Sir William Berkley sent out a company of fourteen English and as many Indians, under Captain Henry Batt, to explore the country to the west. Setting out from the Appomattox River, in seven days they reached the foot of the mountains. The first ridge was not found very high or steep, but after crossing that they encountered others that seemed to touch the clouds, and so steep that in a day's march they could not advance more than three miles. They came upon extensive valleys of luxuriant verdure, abounding with turkeys, deer, elk, and buffalo, gentle and, as yet, undisturbed by the fear of man. Grapes were seen of the size of plums. After crossing the mountains they discovered a charming level country, and a rivulet that flowed westward. Following this for some days, they reached old fields and cabins recently occupied by the natives; in these Batt left toys. Not far from the cabins, at some marshes, the Indian guides halted and refused to go any farther, saying that not far off dwelt a powerful tribe, that never suffered strangers, who discovered their towns, to escape. Batt was therefore reluctantly compelled to return. Upon receiving his report, Sir William Berkley resolved to make an exploration himself, but his intention was frustrated by the troubles that shortly after fell upon the country.[269:A] Beverley alone gives an account of Batt's explorations, leaving the date of it uncertain between 1666 and 1676. Burk dates it in 1667.
