Botany hats played a very conspicuous part in connection with forestry work. Most of us know too little about the published works pertaining to this subject. I shall begin with one of the oldest dendrologists of this country, namely Michaux. I am fortunate to be able to show you here his two volumes of "North American Silva". The father and son were both interested in the subject of plants. The father was sent out by the French Government to explore parts of North America and bring back such plants as were worthy of cultivation, for the French Government. Subsequently, the son also made exploration of parts of North America and the United States, and went on into Canada. The younger Michaux got himself into trouble with the United States because he worked for a French foothold in this country. He settled in the Carolinas and made a trip up the Mississippi.
