CHAPTER XIV.
_Telephones and Telephoning_ MOST men--and women--use more nervous force in speaking through the telephone than would be needed to keep them strong and healthy for years.
It is good to note that the more we keep in harmony with natural laws the more quiet we are forced to be.
Nature knows no strain.

True science knows no strain.

Therefore _a strained high-pitched voice does not carry over the telephone wire as well as a low one._ If every woman using the telephone would remember this fact the good accomplished would be thricefold.

She would save her own nervous energy.

She would save the ears of the woman at the other end of the wire.
