 only substances which can revivify or reanimate a tree. But 

 let those who believe all thoy read follow such advice, and 

 they will soon find that something more is required than the 

 elements which are indicated by the analysis of the chemist. 



An article by Dr. Lindley appeared some time since in the 

 Gardener'' s Chi'onicle, on the power of absorbing and retain-
