 commencement it is seen, that the quantity of Rye 

 far exceeded that of Wheat ; that they gradually 

 approached each other, till the produce of Wheat 

 exceeded that of Rye, and constantly so up to the 

 present time. The physical circumstances of the 

 country are as they were during that long period.

 Roads. There is no ground to suppose that any 

 material, certainly not any observable or recorded 

 increase of population has taken place, except the 

 recent emigration of Germans. 



The whole period of 166 years (Returns of which, 

 as extracted from the City Records of Dantzic, are in 

 the Appendix, No. 24), when divided into periods of 

 about 25 years, exhibits the following Annual Expor- 

 tation of Wheat and Rye from that port. 



The average of the whole period gives an annual 

 quantity of Wheat and Rye, of 279,794 quarters ; 

 and this surplus may be fairly considered as the 

 nearest approach that can be made, with existing 

 materials, to what is the usual excess of the produc-
