In conclusion we beg to remark that the land selected for the trials was iu 
every respect well suited for the purpose. It was so far varied in character as 
fully to test the power of the engines, the strength of the taclde and imple- 
ments, and the suitability of the latter for the various operations by which the 
tillage of the soil is effected. That culture by steam power is destined to 
supersede that by horse-power to an enormous extent can scarcely be doubted 
by those who witnessed the trials. On very light soils cultivation may be 
effected at perhaps as low a price per acre by lioise as by steam power; but we 
think it an error to measure the advantages of the two systems by their direct 
relative cost. It is the time and manner in which it is done that gives 
value to the operation ; for instance, a ploughing or .scarifying during the dry 
autumnal months, may be of the greatest possible benefit, whereas the .same 
operation in the winter might be a positive injury. But as farmers can never 
command a .sufficient amount of hor.se power for the busy season, they must
