the worker on to do his best. It is desirable that the leaves 

 of a note-book be easily taken out. This will enable the 

 teacher to take np single sheets for examination and also 

 make it possible to rearrange them so as to bring the notes 

 relating to one subject together. Only one side of the 

 paper should be used. Every entry should be dated. As 

 a rule nothing but facts discovered by the pupil should 

 appear in the notes. The drawings should be made from 

 the object, not copied. These and the diagrams must 

 clearly show important facts. When it is not expedient to 

 make the drawings natural size the fact should be indicated 

 as shown in the drawings used in this book. For example : 

 if the object is made twice as long and broad as natural put 

 beside it " x 2 "; if it is only half the natural dimensions 

 mark it " x ^." Care should be used in placing the draw- 

 ings upon the page. If the working hour is short only 

 drawings should be made in the class. These may be made 

 with India-ink and a fine pen, or the pencil drawings, after 

 inspection by the teacher, may be inked over. The notes 

 may be written up at home. Only one side of the paper 

 should be used.
