It is most desirable that periods of at least forty minutes should be provided for all the practical lessons. Longer periods will be necessary for some of them, such as the preparation and the serving of a meal. If no practical work is undertaken in the lesson, a forty-minute period is sufficient. LIBRARY ON HOME ECONOMICS FOR THE RURAL SCHOOL In addition to the text-books recommended as sources of special reference for the rural teacher, the following books, bearing on home economics or on methods of teaching, are suggested for the rural school library. These books have been chosen with the threefold purpose of providing references for the teachers, reading matter for the pupils, and a lending library for the parents. _Laundering._ Balderston, L.
