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 New Map of Maryland, 1836. ‘pp. 104, 
with six large folded maps. In two parts: Part 1, by Prof. J. T. 
Ducaren. Annapolis, December 26, 1836, on the geology.—Part 
2, by J. H. Arexanper. 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 Frostburg. 
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, &c. of Maryland appeared in 
this Journal, (Vol. xxv, 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.
