Transcriber’s Notes:
Spelling and punctuation were changed only where the error appears to be a printing error. The punctuation changes are too numerous to list; the others are as follows:
Ditto marks in tables were replaced by the text they represent.
“last” changed to “Last” on page 54. ([Last spring])
“accomodate” changed to “accommodate” on page 60. ([accommodate the increasing numbers of students])
