to me his own discoveries. I soon received valuable contributions 

 from my esteemed friend, the late Gen. E. Kirby-Smith, at Se- 

 wanee; Prof. T. M. Bain, now of the Agricultural College, Knox- 

 ville; Prof. A. Ruth, superintendent of public schools in Knox- 

 ville; the late Mrs. Lydia Bennett, of Fisk University, Nash- 

 ville; Dr. G. Egeling, pharmacist, Memphis; and Prof. Lamson 

 F. Seribner and Mr. Kearney, both now of the Botanical Division 

 of the Agricultural Department at Washington. Much valuable 

 information I drew from the " Memoirs " of the Torrey Botanical 

 Club, in a report; on the flora of Western North Carolina and con- 

 tiguous territories, made by John K. Small and A. A. Heller in 

 the season of 1891, and published in February, 1893, followed by 

 a similar report made in the season of 1892 by John K. Hall and 

 Anna Murray Vail, on the flora of Southwestern Virginia. Both 

 areas extend to the geographical borders of Tennessee, along moun- 

 tain ranges and water courses, which continue into the upper bor- 

 der counties of Tennessee without any difference in the nature of 

 the soil or elevation. The flora being necessarily identical, I took 

 the privilege to add to my list all such species which yet had not 

 been collected within the adjoining boundaries of the State. Most 

 recently I have been favored with valuable information and addi- 

 tions from the botanists of the Biltmore Botanical Institute — 

 Messrs. C. D. Beadle, F. B. and C. L. Boynton, and T. C. Harbi- 

 son — published in "Biltmore Botanical Studies," Vol. I., No. 1; 

 William Wesley & Son, London. From all these sources and 

 my own continued collections, I can now add over four hundred 

 species not contained in the first edition, and am, moreover, en- 

 abled to amend and correct many errors occurring in the same. 



For the census of 1880 I collected for Professor Sargent, the 

 superintendent of the botanical division of the census, specimens 

 of the timbers of Tennessee; I also collected for the mineral di- 

 vision of the same census the building stones of the State, with 

 the exclusion of the marbles. This collection consisted of forty 

 pairs of cubes, all of different character, four by four inches. This, 

 I think, was the first time the granites of Tennessee were brought 

 to notice in beautiful specimens. The eol'lection also contained 

 the sandstones— the beautiful white one from the Hiwassee Valley 

 ■ — and the argillites^ conglomerates, slates, and liniestones, includ- 

 ing the oolitic or Bowling Green stone, which is used in the con- 

 struction of our customhouse.
