The Characters in the Essential English Book (I)
MR. PRIESTLEY

This is Mr. Priestley, the teacher. He teaches English and he knows English, French and German, and he speaks and reads and writes these languages very well.
He is not a young man, but he is not old. He is about forty-four or forty-five years old. He is a good-looking man, tall, handsome, rather thin, with dark-brown hair just begining to go grey. He is always very well-dressed, but quietly, in good taste. He usually wears suits of dark brown, dark blue or dark grey.
He speaks quietly and pleasantly, but there is strenght under his quietness, and every student in his class knows this. He is quiet and pleasent because he is strong. Strenght is generally quiet; weakness often is not.
He reads a great many books, and he writes books for his students. In the picture you can see him sitting in his study, in a big armchair by the fire.
A bright fire is burning in the fireplace. It burns all day in cold weather. Another armchair is on the opposite side of the fire. On his left there is a tray with a coffee pot and a coffee-cup on it, and near to it you can see his pipe and tobacco.
A cat is sitting on the arm of his chair. That is Mr. Priestley's cat, Sully. She often sits there, or on his desk when he is writing, and watches him.
He has a book in his hand and he is reading it. There are books on the shelves all round the walls of his study. More books are on his desk, and some others are on the floor.
His desk is in the middle of the room. Pens, pencils, an incpot and paper are on the desk. The telephone is on the left, and a tray for letters is on the right. Just behind the telephone there is a reading-lamp. He works here at his books for three or four hours every evening.
You can see his typewriter on a little table in a corner of the room. But he can't type very well. He types with only two fingers and a thumb!
It is almost eleven o'clock by the clock on the wall, but Mr. Priestley is still working. He works wery late, sometimes till two or three o'clock in the morning, but generally he goes to bed about twelve or one o'clock.
He often teaches his students in this room. He hasn't many students, generaly about six. They come here for they lessons every day except Saturday and Sunday. Saturday and Sunday are holidays.
