Further Development of Sight
There are two important faculties which are dependent upon the operation of the eye for usefulness and accuracy. They are Visualization and Perception. The games which are given later for the improvement of these important mental operations will also develop the sense of sight.
It will be better to use these later exercises where double results can be accomplished. Give all the time possible to the games on pages 59 to 69.
THE SENSES OF TASTE AND SMELL
For most of the mental operations the three senses already treated are the more important ones. There are some trades in which the senses of taste and smell are also important. These can be cultivated readily by exercises of any nature that stimulate an effort on the part of the children. Many ideas will suggest themselves to you from those given for the other senses.
It is advisable to do a good deal of the practice blindfolded so as to separate entirely the sense of sight, and force dependence upon the senses of taste and smell.
These two senses are very closely allied. Try the experiment of determining the difference in tea, coffee, milk and water while the eyes are covered and the nose held tightly closed.
The degree to which these two senses can be developed is illustrated by the proficiency which is shown by experts and testers who grade tea, coffee and tobacco.
