Transportation facilities in the county are excellent. The Monon 

 and Pennsylvania Lines cross the county. A system of good roads is 

 in existence, about 400 miles of which are macadamized or made of 

 gravel. 



Limestone quarries are located at Monon and recently other deposits 

 have been found several miles southwest of Reynolds. Good clay de- 

 posits and tile factories at Chalmers, Seafield and Wolcott have been 

 in operation for a number of years. 



A far more accurate and much more detailed statement covering 

 the part here alluded to will be found in the forthcoming report of the 

 U. S. Bureau of Soils for White County, which will be ready for dis- 

 tribution within a few months. 



The Native Species of Trees. 



Parts of the summer of 1915 and the fall of 1914 were spent in 

 making collecting trips over various parts of the county. The regular 

 routine work was done single-handed, and the specimens disposed of and 

 mounted according to standard methods now form a permanent part of 

 my private herbarium. 



Realizing very thoroughly that the work of determination, espe- 

 cially in some genera, is not such a self-satisfying matter to any careful 

 botanist, I endeavored to make my collection as authentic as possible. 

 Any specimen still remaining in doubt is either entirely omitted or 

 expressly given as doubtful. 



Specimens in the Purdue Herbarium and many specimens of Oaks 

 and Hickories, collected last summer by Mr. Deam and Prof. Hoffer 

 and recently determined by Sargent, were available for comparison. 

 Dr. Sargent has verified or determined all the specimens of Salix, Hico- 

 ria, Crataegus, Malus, and many Oaks. Mr. F. W. Pennell, Assistant 

 Curator of the New York Botanical Garden, has determined specimens 

 of Fraxinus and Cornus. Mr. W. W. Eggleston of the Bureau of Plant 

 Industry was also consulted. I am permitted to add Salix longifolia 

 variety argophylla (determined by Sargent) to my list, by the courtesy 

 of Mr. C. C. Deam of Bluifton, Indiana, who was ever ready to help. 

 Acknowledgments are also due Professor G. N. Hoflfer of Purdue, not 

 least of which are for a kindly interest in the work. Grateful appre- 

 ciation to Dean Stanley Coulter, under whom this thesis was written, 

 is here expressed, for help, encouragement and his stamp of approval.
