Penfyhania, Philadelphia. tog 



not the whole of Ofiober, are the finefl 

 months in Penjyhania, for the preceding 

 ones are too hot. But thefe reprefent 

 our July and half of Augufi. The greateft 

 part of the plants are in flower in September, 

 and many do not begin to open their flow- 

 ers before the latter end of this month. I 

 make no doubt that the goodnefs of the 

 feafon, which is enlivened by a clear fky, 

 and a tolerably hot fun-mine, greatly con- 

 tributes towards this laft effort of Flora. 

 Yet though thefe plants come out fo late, 

 they are quite ripe before the middle of 

 Oftober. But I am not able to account for 

 their coming up fo late in autumn, and I 

 rather afk, why do not the Centaurea Jacea, 

 the Gentiana, Amarella and Centaurium of 

 Linnaus, and the common golden rod, 

 or Solidago Virgaurea flower before the end 

 of fummer ? or why do the common noble 

 liverwort, or Anemone Hepatica, the wild 

 violets ( 'Viola martia, Linn.) the mezereon 

 (Daphne Mezereum y Linn. J and other plants 

 mew their flowers fo early in fpring ? It has 

 pleafed the Almighty Creator to give to 

 them this difpofition. The weather at 

 Philadelphia during thefe months, is fhewn 

 by my meteorological tables. I have taken 

 the greateft care in my obfervations, and 

 have always avoided putting the thermo- 

 meter
