cases, various artificial processes, affect to a degree the quality 

 of the wine produced ; but, beyond all this, there is something 

 in the locality which is believed to determine its character. The 

 celebrated wine, known as Constantia, is the product of a very 

 limited territory at the Cape of Good Hope. In passing up the 

 Rhine, there was pointed out to me the estate of Prince Metter- 

 meh. where the celebrated Johannisberg wine is produced ; and 

 it is produced nowhere else ; and from this circumstance its pro 

 duction is a source of immense profit. These facts seem to 

 demonstrate the truth of the reply made always to my inquiries 

 in relation to the subject, that there is something as yet unascer 

 tained, some peculiarity in the climate, aspect, or soil, from which 

 the product derived its characteristic properties. The same or 

 similar circumstances may operate upon the quality of wheat ; 

 and it is obvious, as far as they are strictly local, dependent upon 

 the climate and aspect, or upon any peculiarities of the soil which 

 do not exist any where else, or upon any causes as yet unascer 

 tained, they are beyond our reach. 



But that the qualities of the wheat grown depend to a consid 

 erable degree upon the kind of manure employed, there can be 

 no doubt. Some experiments, in reference to this matter, made 

 by a German farmer, may be interesting to my readers. 



Wheats manured as underneath produced as below :

1. With human urine, 35-1 . . 39-3 



2. &quot; oxen s blood, 34-2 . . 41-3

8. &quot; cows, .... 12-0 . . 62-3 



9. Soil not manured, 9-2 .. 66-7* 



1 am unable to say how far these experiments are to be 

 depended on ; and how far they have been confirmed by other 

 experiments made with the same intention. Two things are
