In Fig. 2 the lines cause freedom of movement and train the muscles.
Fig. 3 consists of two-handed exercises intended to try the ingenuity of the pupil by adapting them to more intricate

designs modeled on these examples. Let him add details to these and also other figures given in earlier examples of simple forms.
For two-handed exercises on the blackboard broad, sweeping lines are to be recommended. The lines should be started at about the height of the head, the converging points at about the middle of the chest
Fig. 4 contains suggestions for two-handed exercises, in which the hands work independently.
The lines on the right-hand side of each object are to be
drawn first with the right hand; immediately afterward the opposite half is to be completed with the left hand. Short strokes, as indicated, should be made in the upper figures, and will be found to act as an aid to accuracy. These exercises are adapted for blackboard and pencil.

The pupil need not be discouraged because his drawings look wrong to his own eyes. The time for discouragement will really have arrived (though he won't know it) when he is quite satisfied with his own work.
