to his book: _The Bloody Tenet washed and made white in the Blood of the Lamb_. Cotton’s book quickly found Roger Williams, at his home in Rhode Island, and of course aroused him to write a rejoinder. Its title is a reiteration of that given to his former work, and is likewise a characteristic retort upon the modification made of it by his antagonist: _The Bloody Tenet yet more Bloody, by Mr. Cotton’s Endeavour to wash it white in the Blood of the Lamb_. This book is the most powerful of the writings of Roger Williams. There are three principal matters argued in it,--the nature of persecution, the limits of the power of the civil sword, and the tolerance already granted by Parliament. With Roger Williams, the mood for composition seems to have come in gusts. His writings are numerous; but they were produced spasmodically and in clusters, amid long spaces of silence. He is known to have written two or three works which were never printed at all, and which are now lost. In 1652, he published, in addition to his rejoinder to John Cotton, two small treatises. From that time, no book of his was given to the press until the year 1676, when he published at Boston a quarto volume of nearly 350 pages, embodying his own report of a series of stormy public debates, which he had held in Rhode Island, not long before, with certain robust advocates of Quakerism. This book bears a punning title, _George Fox Digged out of his Burrows_. Besides those of his writings that were intended for books, there are many in the form of letters, some addressed to the public, most of them to his personal friends. In these letters, which cover his whole life from youth to old age, we seem to get very near to the man himself.
