Temperate feafons muft be friendly to meadows and paf- 

 turage, provided we continue to get regular fupplies of 

 rain; but of this, there Is fome reafou to doubt, unlefs 

 our mountains, with which this country happily abounds, 

 fliould befriend us greatly. The decreafe of our frofls 

 and fnows in winter, mull for many years prove injurious 

 to our wheat and winter's grain- The viciffitudes of freez- 

 ing and thawing have already become fo frequent, that it 

 is high time for the farmer to provide fomc remedy, 

 whereby he may prevent his wheat from being thrown 



out In the winter fealbn. 



A confiderable change in the temperature of our feafons, 

 may one day oblige the tobacco planter to migrate towards 

 the Carolinas and Florida, which will be the natural re- 

 treat of that plant, when the feafons admonifli the Virgi- 

 nian to cultivate wheat and Indian corn. The tender vine, 

 which would now be deftroyed by our winter's froft, in a 

 few years fhall fupply the North-American with every 

 fpecies of wine. Pofterity will doubtlefs tranfplant the 

 feveral odoriferous, aromatic, and medicinal plants of the 

 eaftern countries, which muft flourifh in one or another 

 part of North-America, whpre they will find a climate 

 and foil favourable to their growth, as that of their native 

 country. 



Every friend to humanity muft rejoice more in the 



pleafing profpect of the advantages we may gain in point 



of health, from the cultivation or this country, than from 

 all the additional luKuries we may eujoy, though both the 

 Indies were brought to our doors. The falutary effe^ls 

 which have refulted from cleanfing and paving the ftreets 

 of Philadelphia, are obvious to every inhabitant. For 

 caufes fomewhat fimilar to thefe, the general improvement 

 of the colonies have already produced very defirable ef- 

 feds. While the face of this country was clad with woods, 

 and every valley afforded a fwamp or flagnant marlli, by 

 a copious perfpiration through the leaves of trees or plants, 

 and a general exhalation from the furface of ponds and 



marflies,
