Pen/ylvania, Philadelphia* Sj 



part flower fo late, and do not get ripe fruit be- 

 fore the froft overtakes them, although it appears 

 from feveral accounts of travels, that the winters 

 in Penfylvania, and more fo thofe in New York, 

 New England, and Canada, are full as fevere as 

 our Swedi/h winters, and therefore are much fe- 

 verer than thofe which are felt in England. Se- 

 veral men of judgment charged me for this rea- 

 fon to examine and enquire into this phenome- 

 non with all poffible care. But I mail, inftead of 

 an anfwer, rather give a few remarks which I 

 made upon the climate and upon the plants of 

 North America, and leave my readers at liberty 

 to draw the conclufions. 



i. IT is true, that the winters in Penfylvania, 

 and much more thofe in the more northern pro- 

 vinces, are frequently as fevere as our Sweetijh 

 winters, and much colder than the Engli/h ones, 

 or thofe of the fouthern parts of Europe* For I 

 found at Philadelphia, which is above twenty de- 

 grees more foutherv^ than feveral provinces in 

 Sweden, that the thermometer of profeffor Celfius 

 fell twenty-four degrees below the freezing point 

 in winter. Yet I was allured that the winters I 

 fpent here, were none of the coldeft, but only 

 .common ones, which I could likewife conclude 

 from the Delaware's not being frozen ftrong 

 enough to bear a carriage at Philadelphia during 

 my ftay, though this often happens* On con- 

 fidering the breadth of the river, which I have al- 

 ready mentioned in my defcription of Philadel- 

 phia, and the difference between high and low
