On the Trail: An Outdoor Book for Girls by Adelia B. Beard and Lina Beard.There is a something in you, as in every one, every man, woman, girl, and boy, that requires the tonic life of the wild. You may not know it, many do not, but there is a part of your nature that only the wild can reach, satisfy, and develop. The much-housed, overheated, overdressed, and over-entertained life of most girls is artificial, and if one does not turn away from and leave it for a while, one also becomes greatly artificial and must go through life not knowing the joy, the strength, the poise that real outdoor life can give.
