This stack he carried to the window overlooking the front yard. This was the telescope's window. A stool sat nearby. He laid the books on the floor, took the topmost book and climbed the stool.

Through the telescope he could see the city and port, the buildings and ships, the comings and goings. From the books he could see all and everything else.
