Miss ---- gave the B class a lesson in Elocution. She is a very sprightly, animated teacher, and reads well.

Teaching average 100. Miss ---- gave the D class a lesson in History. She is one of the best teachers in her class. She is sprightly, animated, and critical. The lesson was well taught; a map having been neatly drawn on the board, the teacher required the most important places referred to in the lesson, to be pointed out upon it. Teaching average 100. Miss ---- gave the A class a lesson in Chemistry. She has improved very much in teaching. She understood the subject which she taught, and had given the lesson careful preparation. She requested one of the pupils to look for the orthoepy of a word which occurred in the lesson. The lady turned over the leaves of the dictionary in a very careless manner, then took her seat, saying she could not find the word, although she must have been conscious all the while that she was not searching for it in the proper place. Miss ----, instead of sending the lady to look for the word again, as she should have done, pronounced it herself. The teacher should require prompt obedience on the part of pupils. Teaching average 95. Miss ---- gave the C class a lesson in Elocution. She is a very energetic teacher, and manifests a deep interest in her pupils--hence, her success. A visitor would have inferred from her manner, that she was the permanent teacher, not a mere substitute for a passing hour. Teaching average, 100. XXVI.
