As a result of this interview a contract was drawn up between Gutenberg and his apprentices, according to the terms of which each apprentice was to pay the inventor two hundred and fifty florins. The work was to be kept absolutely secret, and in case any of the partners should die during the term of the agreement the survivors should keep the business entirely to themselves, on payment of one hundred florins to the heirs of the deceased partner. Riffe, the third apprentice, was admitted to the business, and after that the four took turns looking after the jewelry shop and working over the blocks for the History.

But the pupils were not so well educated as the master. They could not read, and had to be taught how to draw the different letters. They were clumsy in cutting the lines, and spoiled block after block. Gutenberg was very patient with them. Again and again he would throw away a spoiled block and show them how the letters should be cut properly.

In time the blocks were all finished. “Now I can help,” said Anna. “Thou must let me take the impressions.”

“So thou shalt,” her husband answered. “To-night we will fold and cut the paper into the right size for the pages, and grind the umber for ink. To-morrow we will begin to print the leaves.”

The following day they all took turns making the impressions. Page after page came out clear and true. Then Anna started to paste the blank sides of the sheets together, for the pages were only printed on one side. In a week a pile of the Histories was printed and bound, and ready to be sold.

The jewelers had little time to offer the books to the wealthy people of the city, and so Gutenberg engaged a young student at the Cathedral, Peter Schœffer by name, to work for him. The first week he sold two copies, and one other was sold from the shop. That made a good beginning, but after that it was more difficult to find buyers, and the firm began to grow doubtful of their venture.

The poor people of Strasburg could not read, and could not have afforded to buy the books in any event, the nobility were hard to reach, and the clergy, who made up the reading class of the age, were used to copying such manuscripts as they needed. But this situation did not prevent Gutenberg from continuing with his work. He knew that the young men who were studying at the Cathedral had to copy out word for word the “Donatus,” or manual of grammar they were required to learn. So the firm set to work to cut blocks and print copies of this book. When they were finished they sold more readily than the History had done, and the edition of fifty copies was soon disposed of. But by that time all the scholars of the city were supplied, and it was very difficult to send the books to other cities. There were no newspapers, and no means of advertising, and the only practical method of sale was to show the book to possible purchasers, and point out its merits to them. So Gutenberg turned to two other books that were used by the monks, and printed them. One was called the “Ars Memorandi,” or “Art of Remembering,” and the other the “Ars Moriendi,” or “Art of Knowing How to Die.”

Whenever he printed a new book Gutenberg took it to the Cathedral to show the priests. He carried the “Ars Moriendi” there, and found the Abbot in the library, looking over the manuscripts of several monks.

“Good-morning, my son,” said the Abbot. “Hast thou brought us more of thy magical books?”

“It is not magic, Father; it is simply patience that has done it,” said Gutenberg, handing the Abbot a copy of his latest book.
