The Botanical Club of Canada. 395 



Through the various local secretaries acting under the 

 direction of the provincial secretaries, it is hoped to stimul- 

 ate a spirit of study and research among scholars in the 

 various schools, give aid to more experienced collectors 

 and eventually to distribute accurate data concerning the 

 vegetation of Canada through the publications of local floras. 



The Eecord of Science has been selected by the Club as 

 the recognized medium through which all publications will 

 appear.

The Geology of the State of Maryland. 



There are probably few areas of the same size in which are 

 represented so many geological formations and which also 

 shows such a diversity in surface configuration as does the State of 

 Maryland. The geology of the northern portion of the state and 

 especially that portion about Baltimore has been carefully studied 

 and accurate geological maps are nearly ready for publication. The 

 southern portion of the state has, however, attracted less attention, 

 although one of the finest geological sections through the tertiary 

 to be found anywhere is that exposed along the Chesapeake, Poto- 

 mac and Patuxent rivers. The strata are also very highly fossili- 

 ferous rivaling in this respect the classic tertiary deposits of the 

 Paris basin and we are happy to be able to state that a large collec- 

 tion of these fossils has recently been obtained for the. Peter Red- 

 path Museum of the McGill University. For our knowledge of the 

 geology of this region we are principally indebted to Mr. N. H. 

 Darton, of the United States Geological Survey, whose paper in the 

 last volume of the Transactions of the American Geological Society 

 (vol. ii), entitled "The Mesozoic and Cenozoic Formations of 

 Eastern Virginia and Maryland " gives us the most complete ac- 

 count that has yet appeared of the geology of the " Costal Plain " 

 in these states. 



A further contribution to the Geology and Paleontology of this 

 region is that published in a recent circular of the John Hopkins 

 University (June, 1891) in which Dr. W. B. Clarke gives a resume 

 of the results obtained by the expedition recently fitted out under 

 the joint auspices of the Johns Hopkins University, the Maryland 

 Agricultural College and the United States Geological Survey to
