soils of the State, and the betterment of agricultural practice. 



In the summer of 1876 he made an examination of the gold 

 resources of the nietamorphic region of the State, and had the 

 opportunity during the journeys made for the purpose, to ob- 

 serve also the richness of our flora and especially of the great 

 forests. The results of these observations were published in 

 Berney's Hand Book of Alabama in 1878, under the titles 

 "The Forests of Alabama and Their Products/' and "The 

 Grasses and Other Forage Plants of Alabama." 



The collections of minerals of economic importance brought 

 together during these excursions were placed on exhibition in 

 Mobile in 1876, and in Atlanta in 1881, and a report of the 

 same entitled "On the Economic Geology of Alabama/' was is- 

 sued in 1887. This collection went finally to the Department of 

 Agriculture in Washington. A treatise on the Grasses and 

 Forage Plants of Alabama was prepared for the Department 

 of Agriculture in 1878 and 1879, and in May, 1878, was pub- 

 lished in the Botanical Gazette an account of the useful plants 

 of foreign origin which were acclimated in the Gulf States. 



In the same year, in connection with the State Geological 

 Survey, he began the arrangement of a herbarium of Alabama 

 plants from the collections made by himself and Dr. Smith, 

 and a "Preliminary List of the Plants Growing Without Cul- 

 tivation in Alabama/' prepared by him, was published by the 

 Geological Survey in 1880. 



As a natural sequel to this preliminary work, came the pre- 

 paration of a volume for the Geological Survey on the Plant 

 Life of Alabama, which occupied more or less of his time and 

 interest till his death. 



In 1880, for the Tenth Census, he took charge of an investi- 

 gation of the forestry conditions of the Gulf States, and the re- 

 sults of this investigation were published in Vol. IX of the 

 Tenth Census Reports. While engaged in this work he also 

 collected for the Arboretum at Harvard, and for the Jessup 

 collection of the American Museum of Natural History, large 

 sections of trunks of the typical forest trees. At the same time 

 he brought together the material, afterwards worked up under 

 his direction in book form, illustrating the forest and timber 

 trees of Alabama, which now forms part of the Survey col- 

 lection in the cabinet of the University of Alabama. 



In 1882 he was invited by the chief of the Agricultural De- 

 partment to superintend the arrangement and installation 

 of the Agricultural and Forestry collections which had been 

 brought together by the great railroad lines of the South, and 

 exhibited in Atlanta in 1881. This congenial work occupied 

 him for some time during which he was associated with the scien-
