“It is called the evolution of the book,” added Mrs. Calvert.

The series begins with a picture representing the means that the prehistoric men took to commemorate an event singly—the creation of the cairn, nothing more nor less than the piling up of stones. Then comes a picture illustrating oral tradition—an Arab story writer of the desert. The third represents an Egyptian carving hyroglyphics on a tomb. These are the forerunners and the next is picture writing, represented by an American Indian painting some tribal story or event. In lieu of paper he uses a skin. The fifth is shown by a figure of a monk sitting by the embrasure of his cell, laboriously decorating the pages of some sacred book of the Middle Ages. And finally, the initial attainment of modern methods is shown by a scene in the shop of Guttenburg, where the original printer is seen examining a proof sheet, while an employe looks over his shoulder, and another assistant has the lever of a crudely constructed press in hand.

They all thought this series of pictures a beautiful one, and very interesting.

Dorothy commented, “If they had not discovered how to print and make books, I wonder if we would have had a library like this one here, filled with stones all covered with hyroglyphics?”

“I hardly think so,” answered Mr. Ludlow, “for we could never get so much stone in a building. But come now. We will go upstairs to the little restaurant and sit down and rest for a few minutes.”

So taking the elevator they reached the restaurant which is located in the upper floor of the building, and finding a large table, they seated themselves.

They ordered ice cream for the girls, and the men took lemonade.

While refreshing themselves, Mr. Ludlow said, “I would like to see you all in the morning at ten o’clock. I will then disclose our plans to you for the next few weeks. Also, to-morrow, our number will be increased by three more singers who will join us here. They are Miss Dozzi and Mrs. Helmholz and Signor de Reinzzi.”

Every one said they would be on time in the morning, and started to go back to the hotel. On the way out from the library, Dorothy asked, “Mr. Ludlow, are all these pictures and pieces of statuary done by Italians and other foreigners?”

“No, indeed,” he answered. “The decorations are wholly the work of American architects, painters and sculptors, more than fifty of whom participated in the work. So that, you see, the library is an exhibit of the native art and ability of the citizens of the United States and a memorial to them.”
