To Mr. Ei.t K. Puice, 



Chairman of the Committee on the ]\Iichaux Fund of the American 

 Philosophical Society, and of the Committee on Trees and Nurseries of the 

 Fairmount Park Commissioners. 



Dear Sir : — I have the honor to submit the following as an outline of 

 the proposed Lectures in the Park : 



1. Sketch of Andre Francois Michaux. Outline of the journeys made 

 l)y liim and 1)y his fatlier in North America. The primary object being 

 the introduction into France of American plants and especially American 

 trees. This was an early recognition tliere of the actual necessity of 

 Arboriculture in its relation to the future. Provision made bj- "William 

 Penn, .July 11, 1081, that "in clearing the ground care be taken to leave 

 one acre of trees for every five acres cleared, especially to preserve Oak 

 and Mulberry Trees for silk and shipping.'" Tree destroying tendency of 

 the American people has been matured into an instinct. 



2. Recognized need in Europe of replacing forests destroyed and of pro- 

 tecting those that remain has develo]K'd a matured system of Forestry. 

 Give an outline of this system. 



3. Immediate necessity for some such system in tlie United States, 

 growing out of ruthless destruction of our extreme forests. Immediate 

 action required to prevent serious injury to the future interests of com- 

 merce and of the arts in our country by a continuance of this unrestrained 

 destruction, without any corresponding measures being taken to rejilace 

 the first growth. 



4. Influence of extensive forests (and vegetation generally) on face of 

 country : 1st, from an lesthetic point as illustrated by Humboldt's Views 

 of Nature ; 2d, by either increasing or conserving rain fall ; .3d, by i)re- 

 venting rapid evaporation on one hand and destructive freshets on the 

 other ; 4th, by moderating climate, /. e., warding off destructive winds.
