In the Library is a perfect copy of Eliot's Indian Bible, published in Cambridge in 1661, the last copy of which brought $1,000. Here, too, may be found the works of Cotton and Increase Mather (1671 to 1735), and leading journals, all publications of our country from 1735 to 1800. Bound volumes of many of them can also be found here. The first edition of the Mormon Bible, published in 1830, and printed at Palmyra, New York; Archbishop Cramer's version of the Bible, 1553; Martin Luther's Bible; and the Catholic version of the New Testament, 1582, are among the rare volumes in the Library. An extract from a copy of the Washington _Post_ of 1897 well describes the official test of the device for sending books to and from the Capitol: An official test of the device for transporting books between the Capitol and the new Congressional Library was made yesterday afternoon. Mr. John Russell Young, the Librarian; Chief Assistant Librarian Spofford, and Superintendent Bernard R. Green assembled in the small receiving-room, just off Statuary Hall, about 2 o'clock. Mr. Young had prepared for the test a list of books known only to himself until they were ordered from the Library. The first volume sent for was William Winter's poems. Mr. Young gave out the name and Mr. Green wrote it on a slip of paper. This was placed in the pneumatic tube, which flashed it to Mr. David Hutcheson, who is in charge of the reading-room of the new Library. The book was ordered by Mr. Hutcheson from the shelf-clerk and sent to the desk in the center of the reading-room by the Library carrier. It was then taken to the big carrier in the basement and started on its journey to the Capitol. The time consumed from the moment of sending the order by pneumatic tube until the leather case containing the desired volume deposited its cargo before Mr. Young was exactly ten minutes. Mr. Young then sent for a copy of "Faust" in German, Hugo's "Les Châtiments," and Hildreth's "History of the United States," vol. i., all on one order, and for the London _Times_ of 1815, the year of the battle of Waterloo, on a separate order. The "Faust" and the history arrived in eight minutes and "Les Châtiments" on the next carrier. The order for the London _Times_ was an extreme test, as the volume is so large that the carriers in the Library connecting with the shelves would not accommodate it, and a messenger had to be sent from the main desk to the top deck of the south stack, where the newspaper files are shelved. When the messenger returned he just missed the carrier, which had been sent off with one of the other volumes ordered, and he had to wait the four minutes consumed by the transit of the carriers before he could start the _Times_ on its journey. It arrived at the Capitol just thirteen minutes after the order for it was sent.
