6 RENTAL. 



Does not their ifland lye more expofed to the great Atlantic, 

 and does not the weft wind blow three-fourths of a year ? If 

 there was another ifland yet more to the weftward, would 

 not the climate of Ireland be improved ? Such perfons fpeak 

 equally againftfaft, reafon, and philofophy. That the moifture 

 of a climate does not depend on the quantity of rain that falls, 

 but on the powers of aerial evaporation, Dr. Dobfon has 

 clearly proved. Pbil.Tranf* Vol. Ixvii. part i. p. 244. 



SECTION III. 



Rental. 



NO country can ever be held in a juft eftimation when the 

 rental of it is unknown. It is not the only circumftance 

 which a political arithmetician fhould attend to, but it is a 

 inoft important one. The value of a country is rarely the fub- 

 ject of a converfation without guelTes at its rental being made, 

 and coraparifons between different ones. I contend for nothing 

 more through this and the enfuing tables, than the fuperioriry 

 of aftual information on the fpot, drawn into one point of 

 view, over any guefles whatever. I ftiall therefore proceed at 

 once to lay it before the reader.
