The New Teacher
The school in Pine Clearing was new and fine. The people (be)1 proud of it, as well as of the schoolmistress, a young widow, who was clever and had a good educa­tion.
One day when she (leave)2 the school the chairman of the school board (come)3 up to her, "Mrs Martin, we (like)4 you (have)5 an assistant as the school (get)6 too large for one little woman. I (go)7 (meet)8 him now." At that moment a coach (stop)9 at the gate and they (see)10 a young man (jump)11 out of it. He (look)12 strong and active. His eyes (be)13 blue, his hair (be)14 short; but his face (have)15 no expression, it was like a mask. He (introduce)16 to everybody as Charles Twing, the new assistant. The Chairman (think)17 that he never (see)18 such an expressionless face before; he was sure that as soon as Mrs Mar­tin (look)19 at him she (send)20 him away. Mrs Martin asked Mr Twing if he (be)21 at college, and if he ever (teach)22 at a school. It turned out that he never (do)23 such things. The schoolmis­tress (not say)24 anything to this. She said she (expect)25 him (come)26 to the school early the next day.
The next morning when Mrs Martin came to the school the new assistant (not come)27 yet. But soon he appeared with a crowd of children. They (laugh)28 and (look)29 very happy. Mrs Martin (get)30 angry, but Mr Twing promised that he (listen)31 and (learn)32 very quickly.
A month passed. All (go)33 well in the school. Mrs Martin (begin)34 (like)35 her new assistant and they (become)36 good friends. She never (ask)37 him what he (do)38 before he (be­come)39 a teacher.
