We hear the expression of a book being "worth its weight in gold." "The Bay Psalm-Book," in the Library of the American Antiquarian Society, weighs nine ounces, hence Mr. Vanderbilt paid at least seven times its weight in gold for his precious book. Lowndes's "Bibliographers' Manual" says, "This volume, which is extremely rare and would at an auction in America produce from four to six thousand dollars, is familiarly termed 'The Bay Psalm Book.'" This must have been intended to be printed four to six hundred dollars, and is about as correct as the remainder of the description in that manual. The copy which is spoken of by Mr. Stevens as being in the Bodleian Library at Oxford was once the property of Bishop Tanner, the famous antiquary. Thus it is seen that there are seven copies at least of the first edition of "The Bay Psalm-Book" now in existence in America, instead of "five or at the most six," as a recent writer in "The Magazine of American History" states. And of all the manifold later editions of the New England Psalm-Book comparatively few copies now remain. Occasionally one is discovered in an old church library or seen in the collection of an antiquary. It is usually found to bear on its titlepage the name of its early owner, and often, also, in a different handwriting, the simple record and date of his death. Tender little memorial postils are frequently written on the margins of the pages: "Sung this the day Betty was baptized"--"This Psalm was sung at Mothers Funeral" "Gods Grace help me to heed this word." Sometimes we see on the blank pages, in a fine, cramped handwriting, the record of the births and deaths of an entire family. More frequently still we find the familiar and hackneyed verses of ancient titlepage lore, such as are usually seen on the blank leaves of old Bibles. This script was written in a "Bay Psalm-Book" of the sixteenth edition, and with the characteristic indifference of our New England forefathers for tiresome repetition, or possibly with their disdain of novelty, was seen on each and every blank page of the book:-- "Israel Balch, His Book, God give him Grace theirin to look And when the Bell for him doth toal May God have mearcy on his Sole." What the diction lacked in variety is quite made up, however, in the spelling, which was painstakingly different on each page. Another Psalm-Book bore, inscribed in an elegant, minute handwriting, these lines, which were probably intended for verse, since the first word of each line commenced with a capital letter:-- "Abednego Prime His Book When he withein these pages looks May he find Grace to sing therein Seventeen hundred and forty-seven."
