Amidst their engrossing labours in the capital the two London 'Publishers' did not forget to send news of their work to Friends in the North. Many letters written at this time remain. Those to Margaret Fell, especially, give a vivid picture of their progress. These letters are signed sometimes by Howgill, sometimes by Burrough, sometimes by both together. But, whatever the signature, the pronouns 'I' and 'we' are used indiscriminately, as if to show that the writers were not only united in the service of Truth but were also one in heart. 'We two,' they say in one letter, 'are constrained to stay in this city; but we are not alone, for the power of our Father is with us, and it is daily made manifest through weakness, even to the stopping of the mouths of lions and to the confounding of the serpent's wisdom; eternal praises to Him for evermore. In this city, iniquity is grown to the height. We have three meetings or more every week, very large, more than any place will contain, and which we can conveniently meet in. Many of all sorts come to us and many of all sorts are convinced, yea, hundreds do believe....' Again: 'We get Friends together on the First Days to meet together out of the rude multitude; and we two go to the great meeting place which we have, which will hold a thousand people, which is always nearly filled, there to thresh among the world; and we stay till twelve or one o'clock and then pass away, the one to the one place and the other to another place where Friends are met in private; and stay till four or five o'clock.' Only a month later yet another 'great place' had to be taken for a 'threshing-floor,' or hall where public meetings could be held. To these meetings anyone might come and listen to the preachers' message, which 'threshed them like grain, and sifted the wheat from the "light chaffy minds" among the hearers.' How 'chaffy' and frivolous this gay world of London appeared to these first Publishers, consumed with the burning eagerness of their mission, the following description shows. It occurs in a letter from George Fox himself when he, too, came to the metropolis, a few months later.
