Switzerland, who settled in Charleston in the eighteenth century, 

 in a memorial to the Duke of JSTewcastle, then Secretary of State, 

 sets out with this postulate, that " there is a certain latitude on 

 our globe, so happily tempered between the extremes of heat and 

 cold, as to be more particularly adapted than any other for certain 

 rich productions of the earth; among which are silk, cotton, 

 indigo," &c. — and he fixes on the latitude of 33 deg., whether north 

 or south, as the one of that peculiar character. 



The following Table, showing the climate, duration and pro- 

 daction of certain plants cultivated in tropical America, is from 

 the proceedings of the Agricultural Society of Grenada. The second 

 column gives the altitude in English yards above the level of the 

 sea. The third, the mean temperature by Fahrenheit's thermo- 

 meter. The fourth, the average time required to commence bear- 

 ing. The fifth, the number of plants in a Spanish "fanegada" 

 of 170 varras, about 153 square yards. The sixth, the average 

 duration of each plant. The seventh, the average produce of each 

 plant in the year : — •
