In studying the material provided, whether it be in the class-room, or during a nature excursion, or by observations made in the farmyard at home, the teacher must guide the efforts of the pupils by assigning to them definite and suitable problems. Care must be taken to reach the happy mean of giving specific directions without depriving the pupils of the pleasure of making original discovery. For example, instead of asking them to study the foot of the horse and learn all they can about it, more specific problems should be assigned, such as: Observe how the hoof is placed on the ground in walking. What are the arrangements for lessening the shock when the hoof strikes the ground? Examine the under surface of the hoof and discover what prevents the unshod horse from slipping. NOTE-BOOKS AND RECORDS In Grades higher than Form I, written exercises should be required and also sketches representing the objects studied. For this purpose a Nature Study note-book is necessary--a loose-leaf note-book being preferable because of necessary corrections, rearrangements, additions, or omissions. In all records and reports, independence of thought and of expression should be encouraged. The drawing and the oral or written description should express what is actually observed, not what the book or some member of the class says has been, or should be, observed. The descriptions should be in the pupil's own words, because these are most in keeping with his own ideas on the subject. More correct forms of expression may be obtained when notes are taken from the teacher's dictation, but this is fatal to the development of originality. The disparity of the results in individual work gives opportunity for impressing upon the pupil, in the first place, the necessity for more accurate observation and, secondly, the impossibility of reaching a correct general conclusion without having studied a large number of examples. The development of critical and judicious minds, which may result from carefully observing many examples and generalizing from these observations, is vastly more important than the memorizing of many facts.
