Geological Reports. 191 



The reports of Mr. Lapham and Dr. Locke, we have not seen, 

 if indeed they have made separate reports. A part of that of Prof. 

 Riddell, but without the illustrations, has come to hand. We have 

 no room for its details, which will in due proportion be embodied in 

 the final report. 



IV. Report on the JVeio Map of Maryland, 1836. pp. 104, 

 with six large folded maps. In two parts : Part 1, by Prof. J. T. 

 DucATEL. Annapolis, December 26, 1836, on the geology. — Part 

 2, by J. H. Alexander. Baltimore, February 15, 1837, on the 

 topography and engineering. 



The Report of the geologist contains — 



Sec. 1. Geological examinations of Calvert county, in reference 

 to its agricultural resources. 



Sec. 2. On the present condition of agriculture in Calvert county 

 and the means of improving it. 



Sec. 3. Geological examinations made in Ann Arundel county. 



Sec. 4. Geological examinations made in St. Mary's, Charles and 

 Prince George's counties. 



Sec. 5. Excursion into Allegany county, with preliminary obser- 

 vations on the geology of the country, from the Atlantic tertiary de- 

 posits to the bituminous coal region of Frosiburg. 



Sec. 6. Description of the Frostburg coal-field. 



Sec. 7. Description of the maps and sections that accompany the 

 Report. 



An introductory view of the geology, &ic. of Maryland appeared in 

 this Journal, (Vol. xxvii, p. 1,) and we are happy to see that the out- 

 line then sketched, has been so far and so ably filled up by Professor 

 Ducatel, whose own communication on this subject, (which he has 

 encouraged us to expect in a future No.) we will not anticipate by any 

 remarks. 



Mr. Alexander's Report on the topography, rail road, and canal 

 capabilities, contains a great amount of exact and valuable information 

 of the greatest importance to the State of Maryland. This Report 

 relates to the Coptank and Transquallin Canal, and to the Atlantic 

 Rail Road. 



We trust that the State of Maryland will fully carry out the views 

 of their able engineer, and thus sustain a successful although friendly 

 rivalry with the neighboring states, which are doing so much for the 

 great cause of internal improvement.
