In the northern parts of Pennfylvania there are 

 great quantities of a fpecies of pine called hemlock; 

 which with beech, birch, fugar and other maple, 

 afh, elm, wild cherry, and fome few others, con- 

 ftitutc the timber of the country. 



When at Philadelphia I was feveral times in com- 

 pany with a perfon who had fettled about 1 50 fa- 

 milies on a traft of land called Oifego, at the head 

 waters of the Sufquehannah j the place was a wil- 

 dcrnefs in the year 1784, not a fingle family withinr 

 many miles of it; I am fince informed that laft 

 feafon he colledled from thofe families, his own 

 fetders, and brought for fale, 30 tierces of maple 

 fugar that weighed from 5 to 6 cwt. each. 



I have now done with the fubjeft of the fugar 

 maple; but as I am addrefling myfelf to a gende-

 promotion of agriculture, I (hall juft mention an 

 article of manure in great ufe in Pennfylvania, that 

 is fcarcely known as fuch here. There are many 

 hundred tons of plaifter of Paris imported yearly 

 into Philadelphia from France and Nova-Scoda; 

 it has generally been fold by the cargo from fix to 

 eight dollars per ton weight; it is firlt broken into 

 fmall pieces by pounding, and then ground between 

 a pair of mill-ftones to a powder, aftd ufed in this
