Kentiick}^ Geological Survey, which he held until 1885. His first work 

 there was on the geology and agricultural features of the "Jackson Pur- 

 chase" region of Kentuck}^, embracing descriptions of five counties. Tliis 

 report was published in 1888. His report on Clinton County, Kentucky, 

 was printed in 1890, but his manuscripts of similar reports on Livingston 

 County and on Meade County were turned over to the State Bureau of 

 Mines, on the suspension of the G-eological Survey, and have never been 

 printed. 



For the next fi.ve years, from 1885 to 1890, Loughridge was Professor of 

 Agricultural Chemistry in the University of South Carolina, at Colum- 

 bia. During this time he contributed several articles to the reports of the 

 experiment station. 



Returning to California in 1891, he again became Hilgard^s valued as- 

 sistant and associate in the study of the soils and agricultural conditions 

 of California. Some of these investigations were conducted jointly with 

 Doctor Hilgard, but most of them independently, though generally along 

 the lines of Hilgard^s researches and often at his suggestion. At the time 

 of his death he was engaged in the preparation for publication of a large 

 amount of data collected by himself, Doctor Hilgard, and other members 

 of the Department of Agriculture of the University of California. 



The quotations given below, from friends who have known him most 

 intimately, will perhaps best set forth the personality of Doctor Lough- 

 ridge and his character. 



Dr. David P. Barrow, chancellor of the University of Georgia, who was 

 intimately associated ^dth Doctor Loughridge when they were both con- 

 nected with the Geological Survey of Georgia, writes concerning him: 



"I was impressed with his quiet manner and his orderliness in all that he 

 undertook. It seemed to me, that he was very precise as a boy, I thought too 

 much so, but I learned from him somewhat of the value of system, and a great 

 deal of the strength which may be under a quiet, diffident manner. 



*'He taught me something of the amount one may accomplish by saving scraps 

 of time. I do not recall any one with whom I have associated who was quite 

 so careful of time as was Doctor Loughridge. He was always on a high plane 

 in conduct and in his talk." 



One trait of liis character which commanded the admiration of his 

 friends was his devotion to Doctor Hilgard, with whom he was closely 

 associated from his early manhood. This friendship and his unselfish 

 cooperation were fully appreciated by Doctor Hilgard, from whom we 

 quote the following paragraphs published in the University of California 

 Journal of Agriculture of May, 1915 : 



''During a lifetime devoted to research and instruction in agricultural sci- 

 ence. Dr. R. H. Loughridge has most comprehensively redeemed the promise
