the lecturer was in the prime of his manhood, at thirty years, 

 and had already developed those charming qualities of method 

 ami discourse which always made it a pleasure to follow him, 

 even on subjects of no more than ordinary interest. 



In 1835 Professor Rogers organized a geological survey for the 

 State of Virginia, but after several years of a struggling exist- 

 ence and the publication of some annual reports of progress, in 

 1842, the effort was abandoned for want of any adequate support 

 from the State. The materials accumulated for a final report 

 have never been published, but Professor Rogers united with 

 his brother, Henry Darwin Rogers, geologist of Pennsylvania, 

 in the authorship of a memorable memoir on the structure 

 of the Appalachians in Pennsylvania and Virginia. This paper 

 WM jointly presented by the two brothers, at Boston, in the 

 autumn of 1842, before the session of the American Association 

 of Geologists and Naturalists. It evcited the una test interest 

 among geologists and physieisis ,,n account of the novelty of its 

 views, supported as they were by ample data and numerous sec- 

 tions, and the eloquence with which the whole subject was set 

 forth. This was the first, important contribution to dynamical 

 and structural geology which, up to that time, had been brought 

 forward in this country. With it appeared, also for the first 

 time, the notation and nomenclature of the Appalachian system 

 of rocks, now so familiar, through the Reports of the Geoh'.gical 

 Survey of Pennsylvania. An important paper on the "Connec- 

 tion of Thermal Springs in Virginia with Anticlinal Axes and 

 Faults," by Professor William B. Rogers, was presented at the 

 same meeting, and both papers were published in the Transac- 



But probably th most important life work of Professor Rogers 

 was that connected with the Massachusetts Institute of Technol- 

 ogy at Boston, an institution which owes its existence, mainly, to 

 his zeal and untiring industry, through which, in I860, f861, he 

 secured for it the support of the State and of individual founders. 

 The work was crowned with success, and in 1862 Professor 



Rogers was made presi an office which he 



held until 1868, when his health failed him owing to overwork. 



In 1878, upon the death of Professor Joseph Henry, Professor 

 Rogers was elected to the presidency of the National Academy
