ARNOLD HENRY GUYOT. 497 



regard to these books : " It is not too much to say that they 

 revolutionized the methods of teaching geography. Every 

 series of geographies which has since appeared shows the influ- 

 ence of Guyot." He threw aside the old routine methods, and 

 brought his pupil face to face with Nature, showing the bear- 

 ing of the earth's physical features upon every department of 

 human interest. His geographical works received the medal 

 of progress at the Vienna Exposition of 1873, and a gold medal, 

 the highest award, at that of Paris, in 1878. 



Another pre-eminent service which Guyot rendered to Ameri- 

 ca was the work he did in meteorology, a science which had 

 received very little attention when he arrived in this country. 

 From 1851 to 1859 he worked at the preparation of the Meteor- 

 ological and Physical Tables, published by the Smithsonian In- 

 stitution, and also superintended the construction of accurate 

 meteorological instruments. In connection with Prof. Henry 

 he did much to establish the system of weather observations 

 and reports which has resulted in the Government Weather 

 Bureau. 



In 1854 Guyot was elected to the chair of Geology and 

 Physical Geography at Princeton, a post which he filled for the 

 thirty remaining years of his life. Until compelled to cease by 

 the increasing infirmities of age, he devoted all his vacations 

 and spare time to his favourite investigations, making elaborate 

 and careful examinations of the mountains from New England 

 to South Carolina. This work involved an immense amount of 

 hardship and fatigue, and he was fond of describing with quaint 

 picturesqueness and humour his experiences in roughing it in 

 the mountains of Pennsylvania and the Carolinas. In 1861 he 

 published in the American Journal of Science and Arts the re- 

 sults of his work up to that time, " a memoir which remains to 

 this day the best existing description." Again, in 1880, he 

 brought out another memoir on the same subject, devoted 

 chiefly to the Catskills, some of the rough work for which was 

 done after he was seventy years old. Many shorter papers on 

 meteorological, physical, and geographical subjects were writ- 

 ten at intervals. His work during this period is a noble ex- 

 ample of what may be done without appropriations or endow- 

 ments, for in those days Princeton was very poor, and he had 

 to do as best he could without assistance. 



As a friend and teacher Guyot will ever be held in loving
