Penjyhatiia> Philadelphia. Ill 



NEAR the town, I faw an Ivy or Hedera Helix, 

 planted againft the wall of a ftone building, 

 which was fo covered by the fine green leaves of 

 this plant, as almoft to conceal the whole. It was 

 doubtlefs brought over from Europe, for I have 

 never perceived it any where elfe on my travels 

 through North America. But in its ftead I have 

 often feen wild vines made to run up the walls. 



TASKED Mr. Bartram, whether he had ob- 

 ferved, that trees and plants decreafed in proper* 

 tion as they were brought further to the North, 

 as Catefby pretends 5 he anfwered, that the quef- 

 tion fhould be more limited, and then his opinion 

 would prove the true one. There are fome trees 

 which grow better in fouthern countries, and be- 

 come lefs as you advance to the north. Their 

 feeds or berries are fometimes brought into colder 

 climates by birds and by other accidents. They 

 gradually decreafe in growth, till at laft they will 

 not grow at all. On the other hand, there are 

 other trees and herbs which the wife Creator 

 deftined for the northern countries, and they 

 grow there to an amazing fize. But .the further 

 they are tranfplanted to the fouth, the lefs they 

 grow; till at laft they degenerate fo much as not 

 to be able to grow at all. Other plants love a 

 temperate climate, and if they be carried either 

 fouth or north, they will not fucceed well, but 

 always decreafe, Thus for example, Penfylvania 

 contains fome trees which grow exceedingly well, 

 but always decreafe in proportion as they are car- 

 ried further off either to the north, or to the fouth. 



I AFTERWARDS, on my travels, had frequent 

 proofs of this truth. The Sajjqfras, which grows in
