 vifable to make the firft trial at this fettlement, to learn in what way the propagation of

Mifcdlaneous Obfervations relative to the Wejlern Parts of Pennfylvania, particularly thoje 

 in the Neighhourhood of Lake Erie. By Andrew Ellicott *. 



Dear Sir, 



I 



TAKE the liberty of tranfmltting to you the following mifcellaneous obfervations, col- 

 leded fiom my notes, relative to Lake Erie, and the Weftern Country, the perufal of which 

 I flatter myfelf will not be unfatisfadtory or uninterefling. 



The fituation of this lake is already well known, and therefore a particular topographical 

 defcription will here be unneceflary ; but a variety of phenomena which attend it, merit a 

 more minute confideration, and cannot fail to engage the attention of the philofopher ; 

 phenomena which in all probability are common to all large lakes of frefli water. 



In the fummer feafon fogs are feldom obferved on the margin of the lake. The three 

 fummer months that I refided at Prefqu' Ifle, no fogs were feen during the whole time. 

 The horizon was generally clear, and the ftars flione with remarkable luftre. The moft 

 common winds here generally refemble the fea and land breezes, in the Weft Indies. 

 From the end of fpring till the beginning of autumn, they blow, except at the time of 

 ftorms, from the lake upon the land during great part of the day, and from the land upoa 

 the lake during the night : the change generally takes place between the hours of feven and 

 ten in the morning, and about the fetting of the fun in the evening. Thefe breezes, alter- 

 nately blowing in oppofite direiElions, render thofe fituations contiguous to the lake ex- 

 tremely pleafant during the heat of the fummer months, and have moft probably a very 

 falutary influence upon the atmofphere. 



A ftrong eafterly wind will occafion a confiderable depreffion, and a ftrong weftcrly wind 

 a confiderable fwell of the waters in Prefqu' Ifle Bay. In the former cafe, a portion of the 

 water is driven towards the upper end, and in the latter, towards the lower end of the lake. 

 To thefe caufes we are to attribute thofe ebbings, and Sowings, which have fo frequently 

 been miftaken for regular tides : for a little rcfleftion will convince one, that the moon can" 

 have no fenfible effeft upon the waters of the lakes. When the wind ceafes the waters re-
