* This is the only tree of the Indian nut piue known to exist on the front or middle ranges of our 

 Pasadena mountains, and it has a history. On October 10, 1887, Jason and Owen Brown built a cairn on 

 this mountain top. iSee page 369, '• Mt Lowe."l They noticed this rare tree, with its roots so much 

 denuded by rain-wash and wind that it was ready to die ; and they gathered and brought soil in their 

 little tin dinner pail to pack around its exposed roots, thus saving its life at that time, and hence it has 

 been called the "Osawatamie pine tree." Then on August 15. 1S93, Dr. Reid and wife found it perishing 

 again from the same causes; and Mrs Reid gathered loose dirt and mulch from between rocks and 

 dragged it on an old barley sack which she had found, to the roots of the tree, while the Doctor laid up 

 a wall of rocks on the lower side to hold the dirt in place ; and so its life was saved again They also 

 broke off some of its dead branches, to give the live part a better chance. The tree was then ten or 

 twelve feet high. There are said to be some trees of the same species on Sau Gabriel peak, but this is 

 not yet verified by competent testimony. — Ed.
