Professor Coville s work. — When the work of the Geolog- 

 ical Survey of the State was begun in 1887, several collateral 

 branches of work were taken up with the purpose of adding 

 to our knowledge of the natural history of the State in what- 

 ever way such additions could be made without interfering 

 with the more direct and specific duties of the Survey. Among 

 other things a list of the plants of the State was begun and 

 added to by the various members of the Survey. In the 

 summer of 1888, Professor F. V. Coville, then Instructor in 

 Botany at Cornell University, now of the Botanical Division 

 of the United States Department of Agriculture at Washing- 

 ton, was induced to spend some months in the State, partly 

 for the purpose of giving proper direction to the botanical 

 work. And it is to Professor Coville's efforts, both in the field 

 and in the laboratory, more than to any other one person's 

 labors, that the present list owes its value. 



His field work was done in the vicinity of Little Rock and 

 in Independence county where he made collections of plants 

 and studied their relations to soils and to geologic structure.
