Set the two front nails well towards the toe, so as not to be more than two inches apart when measured across the bottom of the foot.  Let the next two divide the distance from that to the heel, so as to leave from two to two and a half inches free of nails, as the form of the foot may allow.  Lastly, before nailing on the shoe, and while it is cold on the anvil, strike the surface that comes next to the foot on the outside, a few blows with the hammer, right across the heels, and see also that the outside of the heels is a shade lowest, so that the animal in throwing his weight upon them will spread out, and not pinch in his feet.
