In consequence of a recommendation by his excellency Gov. 
Edwards, the Legislature of Connecticut, in May, 1835, resolved—

mittee of suitable persons to make a geological survey of the State 
of Connecticut, and to report the same to the General Assembly. at 
their May session of 1836. In consequence of this resolution, the 
Governor appointed Dr. James G. Percival and Prof. Charles U. 
Shepard to make and report on the proposed examination. 
These gentlemen having divided the labor, Mr. Shepard has re- 
ported on the economical mineral resources, and on the scientific 
mineralogy of the State. 
Dr. Percival’s report on the geology, is, by permission of the 
legislature, deferred another year, that he may have time to finish 
his work. 
It is impossible for any competent judge of the matter to peruse 
Mr. Shepard’s report without being convinced that he has brought 
to the task all the industry, perseverance, and science that were 
demanded, and that he has been particularly attentive to the practi- 
cal interests of the community. ‘The result of this examination, as
