bles. Such is the case on the sides of almost all high 

 mountains ; and such was evinced in a very striking 

 manner, in the neighbourhood of Baltimore, and in ma- 

 ny places in Baltimore county and elsewhere, during 

 the dreadful fall of rain which was experienced, in al- 

 most every part of the United States, in July 1817. 

 In this instance, rocks of granite of many tons weight 

 were hurried down the streams a quarter of a mile or 

 more, and that almost on a perfect level. 



With respect to the masses of granite in the state of 

 Ohio, and in the neighbourhood of Cincinnati, and also 

 in the states of Kentucky and Indiana, the case is very 

 different. There are no mountains within a great dis- 

 tance, from which they could have been torn ; neither 

 are they on the bottom, or on the margins of rivers, 

 -from whose sources they could have been brought, 

 either by the current or by ice ; but promiscuously in- 

 terspersed over a great extent of country, which is, be- 

 yond all doubt, decidedly alluvial. 



Neither is there any known volcano from which they 

 could have been thrown ; or, if there were such, the ju- 

 dicious remarks of Dr. Drake on the subject, are suffi- 

 cient to remove all doubts on that point, (viz :) " that 

 their surfaces discover no signs of vitrification, and 

 their distribution too much in groups to favour this 

 suggestion."* 



Hence, there remains no point or incident on which 

 the mind can fix, that will explain this phenomenon,
