At that time, the colliers of Kingswood, near the city of Bristol, were a most depraved and reckless class of men. Inconceivably barbarous and ignorant, they trampled on all laws, human and divine, and hesitated not to set the magistrates at defiance. It was dangerous to pass near the scene of their labors, even in open day, for robberies and murders were of frequent occurrence; in a word, it was truly "a seat of Satan." When Whitefield was at Bristol, making collections for his projected orphan institution in Georgia, not a few persons had said to him, "Why go abroad; have we not Indians enough at home? If you have a mind to convert Indians, there are colliers enough in Kingswood." "I thought," says he, "it might be doing the service of my Creator, who had a mountain for his pulpit, and the heavens for his sounding-board, and who, when his gospel was refused by the Jews, sent his servants into the highways and hedges." After much prayer and many inward struggles, he went one day to a gentle elevation on the south side of Kingswood, called Hanham Mount, and there, under an old sycamore-tree, he preached his first sermon in the open air to about a hundred colliers. The scene must have been very impressive. Before him stretched the rich and beautiful valley of the Avon, through which the river was gently winding, bordered in the distance by the undulating hills; while on his right and left the cities of Bath and Bristol were within sight. The fact of his preaching here soon and extensively spread, and at meeting after meeting his audience increased, till he found himself addressing _nearly twenty thousand persons_. His own account of the effects produced is very striking. He says, "The first discovery of their being affected, was in the white gutters made by their tears, which plentifully fell down their black cheeks, as they came out of their coal pits. Hundreds and hundreds of them were soon brought under deep convictions, which happily ended in sound and thorough conversion. As the scene was quite new, and I had just begun to be an extempore preacher, I had often many inward conflicts. Sometimes, when twenty thousand people were before me, I had not, as I thought, a word to say; but I was never deserted; and I was often so assisted as to understand what that meaneth, 'Out of his belly shall flow rivers of living water.' The open firmament above; the prospect of the adjacent fields; with the sight of thousands and thousands, some in coaches, some on horseback, and some in the trees, and all so affected as to be drenched in tears together, to which sometimes was added the solemnity of the approaching night, were almost too much for me; I was occasionally all but overcome." Writing to Mr. Wesley a few weeks afterwards, he says, "Yesterday I began to play the madman in Gloucestershire, by preaching on a table in Thornbury-street. To-day I have exhorted twice, and by and by I shall begin a third time; nothing like doing good by the way. I
