 gravel, and move the carriage too, ( for so it did, 

 only not fast enough for modern travelers,) what

 that he should spare off a little of his redundant 

 steam in moving his own carcass along meanwhile, 

 at a pace of little more than half a mile an hour? 

 "What you save in speed you gain in power ;" and

 which completes the whole work of tillage, as it 

 moves along, will hardly be required to go much 

 faster. At that speed it would cover four acres a 

 day not of "plowing," not of " harrowing," not of 

 "rolling," not of scuffling," not of "rolling again"
