[N. S. Vol. XIX. No. 483. 



and, as there seems no doubt, all of its component 

 bureaus. 



Greater promptness in the publication of re- 

 sults in a monthly magazine than in quarterly, 

 annual or occasional journals, etc., as is now the 

 case in several instances. 



A larger and more important audience to be ad- 

 dressed on geographical themes, and hence greater 

 inducement for careful preparation and greater 

 care in writing. 



Greater dignity and greater influence of one 

 strong publication than of many, several of which 

 are weak. 



The employment of one instead of several 

 editors, thus saving both time and money. 



Greater revenues to be expected from advertise- 

 ments from one widely circulated magazine than 

 in the case of several local journals, etc., as at 

 present, but few of which derive any assistance 

 from this source. 



The greater inducements which one widely cir- 

 culated magazine would have in securing contribu- 

 tions from dis^nguished investigators, well-known 

 explorers, etc., over a less widely distributed pub- 

 lication. 



The probability that the proposed magazine, on 

 account of its increased earning power over that 

 of the several local publications now issued, would 

 be able to pay for leading articles. 



Important also is the fact that the con- 

 centration of geographical literature in one 

 series of volumes, instead of several inde- 

 pendent series as at present, would be con- 

 ducive to the saving of time and energy on 

 the part of all future generations of geog- 

 raphers who may wish to consult the 

 writings of their predecessors. In order 

 to gain these many and great advantages, 

 geographical societies are asked to relin- 

 quish some of their purely local interests 

 and look for compensation for such losses 

 in the wider diffusion of geographical in- 

 formation and a more general awakening 

 to an interest in geographical work. 



Fossiliferous Sandstone Dikes in the Eo- 

 cene of Tennessee and Kentucky: L. C. 

 Glenn. 



Fossiliferous sandstone dikes are found 

 to occiir in basal Eocene clays in Tennessee 

 and Kentucky. The dikes have no definite 



orientation. They vary in width from 

 mere stringers to masses several feet in 

 width. The fossils are casts and are of 

 Eocene aspect. The sands filling the fis- 

 sures are micaceous and are regarded as 

 derived from certain Eocene sands inter- 

 bedded with the clays. There is no definite 

 evidence as to their mode of origin, but as 

 the region has recently suffered repeated 

 earthquake shocks, it seems probable that 

 it has similarly suffered in the past and 

 that the fissures are of earthquake origin. 



The Fauna of the Potter Creek Cave: W. 

 J. Sinclair. Presented by J. C. Mer- 

 riam. (Illustrated with lantern slides.) 

 The Potter Creek cave contains fossil re- 

 mains representing a Quaternary fauna 

 which has heretofore been very imperfectly 

 known. Recent explorations in this and 

 adjacent caves have brought to light over 

 fifty species of mammals and birds. Of 

 this number many forms are new. The 

 paper treats of the occurrence of the re- 

 mains and the general relationship of the 

 fauna. 



Evidence of Recent Differential Movement 

 along the New England Coast: Geo. 

 Carroll Curtis. (Read by title.) 

 Evidence of change of level of the land 

 in respect to the sea in recent geologic time 

 has been noted by Shaler, De Geer, Stone 

 and Willis. . Davis has described a coastal 

 plain of recent origin in the vicinity of 

 Portland. Tarr and Woodworth lately re- 

 port shore lines on Cape Anne up to eighty 

 feet. A range of earlier shore margins 

 from a few feet above tide in Boston Bay 

 to 1,300 feet or more on Mount Desert has 

 thus been recorded. Detail study within 

 this zone, however, indicates that these 

 movements have not been continuous. On 

 Monhegan Island, ten miles off the middle 

 coast of Maine, there are strongly marked 

 shore lines 160 feet above present sea level, 

 with an amount of wave work in the hard
