 receives in compensation only some £ 67,500, or 

 300,000 dollars, and therefore voluntarily renounces 

 a gain from five to six times greater, which it might 

 derive from these exports. 



These figures, which have been drawn not merely 

 from theoretical speculations, but from the practical 

 testimony and experience of agriculture itself, ought 

 to convey to every German farmer, in a voice of 

 warning, the following admonition : " Keep what 

 thou hast, and manure with thy wares, not foreign 

 fields, but thine ownP In Saxony this is done al-

 extended the practice of manuring with rape-meal, 

 partly in consequence of multifarious information re- 

 specting the constituents and strength of this ma- 

 nure, and partly in consequence of the recurrence of 

 a deficient supply of guano and bone-dust, which

 with respect to the magnitude of the yearly con- 

 sumption cannot indeed at present be brought for- 

 ward ; but no great error will be committed in as- 

 suming that Saxon agriculture itself now consumes 

 again the residuum of the oleaginous seeds, whose 

 cultivation in Saxony, and even in its mountainous 

 regions, has received during the last ten years a very
