Moorfields, just without the limits of the old north city wall of London, was, a few years before Whitefield first knew it, a marsh, and during the greater part of the year, was absolutely impassable. Having been partially drained, a brick kiln was erected, and the first bricks used in London are said to have been manufactured there. Afterwards it was a field for the practice of archery, when it was laid out in walks, and called the City Mall. Though improved in name and appearance, it became the rallying ground for the rabble of London; wrestlers, boxers, and mountebanks, the idle, the dissolute, and the profane, held here their daily and nightly revels. It appeared, in fact, to be one of the strong-holds of Satan, and therefore became a most tempting and important point of attack for the daring eloquence of Whitefield. All London rang one day with the announcement that Whitefield would preach the day following at Moorfields. This was in January, 1739. Gillies says, "The thing being strange and new, he found, on coming out of the coach, an incredible number of people assembled. Many told him that he would never come out of that place alive. He went in, however, between two friends, who by the pressure of the crowd were soon parted from him entirely, and obliged to leave him to the mercy of the rabble. But these, instead of hurting him, formed a lane for him, and carried him along to the middle of the fields, where a table had been placed. This, however, having been broken by the crowd, he mounted a wall, and preached to an exceeding great multitude in tones so melting, that his words drew tears and groans from the most abandoned of his hearers. Moorfields became henceforth one of the principal scenes of his triumphs. Thirty thousand people sometimes gathered together to hear him, and generous contributions here poured in for his orphan-house at Bethesda. On one occasion twenty pounds--about one hundred dollars--were received in half-pennies, more than one person was able to carry away, and enough to put one out of conceit with a specie currency."
