whole machine would move north only the width of a furrow, while in length the furrow would be a rod from east to west. In such case a very large proportion of the power would be applied to the actual plowing. But in this, too, there would be difficulty, which would be the getting of the plow into and out of the ground, at the end of all these short furrows.
I believe, however, ingenious men will, if they have not already, overcome the difficulty I have suggested. But there is still another, about which I am less sanguine. It is the supply of fuel, and especially water, to make steam. Such supply is clearly practicable; but can the expense of it be borne? Steamboats live upon the water, and find their fuel at stated places. Steam-mills and other stationary steam-machinery have their stationary supplies of fuel and water. Railroad-locomotives have their regular wood and water stations. But the steam-plow is less fortunate. It does not live upon the water, and if it be once at a water-station, it will work away from it, and when it gets away cannot return without leaving its work, at a great expense of its time and strength. It will occur that a wagon-and-horse team might be employed to supply it with fuel and water; but this, too, is expensive; and the question recurs, "Can the expense be borne?" When this is added to all other expenses, will not plowing cost more than in the old way?
It is to be hoped that the steam-plow will be finally successful, and if it shall be, "thorough cultivation"—putting the soil to the top of its capacity, producing the largest crop possible from a given quantity of ground—will be most
