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.
The usefulness of their development is to a large degree only of value to those engaged in these lines of trade. The opportunity for their development comes rarely except in connection with work in the trades, and for that reason will not be dealt with at any length here.
