 before praised as well adapted to the soil. One of these, 

 with a plough in use on the Bergstrasse, a Flemish wheel,

 other in a dry stony soil, the result was: —

Sowing-machines are only in use for rape, and occa- 

 sionally for turnips. Where seed is abundant and labour 

 cheap, the outlay for expensive machines is not repaid, as 

 is the case where labour is dearer. This principle is 

 further confirmed by experiments that have been made 

 with the Scotch threshing-machine as Modified by M. 

 Dombasle, in Alsace. For small quantities the advantage 

 of machinery is scarcely apparent ; but machinery ap- 

 plied to large quantities produces a great saving. Expe- 

 riments made in Germany have shown that where —
