His next extant piece of work is an almanac for 1650, his next the third edition (the second, as noted above, had been printed at London in 1647) of the Bay Psalter, "printed by Samuel Green at Cambridge in New-England, 1651." This was followed in 1652 by Richard Mather's _The Summe of Certain Sermons upon Genes_. 15. 6, a treatise on Justification by Faith, and then Green seems to have begun to busy himself with work for the Corporation in England for the Propagation of the Gospel amongst the Indians in New England, or Corporation for the Indians, as it is easier to call it. A second press was sent over to enable this work to be undertaken, and a Primer by John Eliot ("the Apostle to the Indians") was printed in 1654, and the Books of Genesis and Matthew the next year, all three in the Indian language, all three now known only from records. The same destruction has befallen an Indian version of some of the Psalms mentioned as having been printed in 1658, but of another Indian book of the same year, Abraham Peirson's _Some helps for the Indians, shewing them how to improve their natural reason to know the true God, and the true Christian Religion_, two issues have been preserved, one in the New York Public Library, the other at the British Museum. Another edition, dated the next year, is also at the Museum, though it has escaped the notice of Mr. Evans, the author of the latest "American Bibliography." By this time the Corporation for the Indians had sent over a skilled printer, Marmaduke Johnson, to aid Green in his work. Unfortunately, despite the fact that he had left a wife in England, Johnson flirted with Green's daughter, and this conduct, reprehensible anywhere, in New England brought down on him fines of L20 and a sentence of deportation, which, however, was not carried out. Johnson's initials appears in conjunction with Green's in _A Brief Catechism containing the doctrine of Godlines_, by John Norton, teacher of the Church at Boston, published in 1660, and the two men's names in full are in the Indian New Testament of 1661 and the complete Bible of 1663. Of the New Testament it is conjectured that a thousand, or perhaps fifteen hundred copies, were printed, of which five hundred were bound separately, and forty of these sent to England. How many copies were printed of the Old Testament is not known, but of the complete Bible some forty copies are still extant in no fewer than eight variant states produced by the presence or absence of the Indian and English titlepages, the dedication, etc., while of the New Testament about half as many copies may be known.
