Engineers.
The rapid movement of an army and its supplies wins victories and makes possible the execution of effective strategy.
Road-making is no less essential to the success of a soldier than the handling of a musket.
The upper photograph shows Major Beers of the Fiftieth New York Engineers, on horseback, directing his battalion at road-making on the south bank of the North Anna River May 24, 1864.
A wagon-train of the Fifth Corps is crossing the bridge by Jericho Mills, constructed on the previous day by Captain Van Brocklin's company of the Fiftieth New York Engineers.
In the lower photograph Major Beers has apparently ridden away, but the soldiers are still hard at work.
The wagon-train continues to stream steadily over the bridge.

substitution of augers of different sizes.
The lower extremity of the revolving portion holds the center-bit m, which, owing to the collar n, cannot ascend or descend without the square cutter which cuts out the angles beyond the range of the circular borer.
The square-cutting tool is a bar of steel with a round hole drilled out of the solid, and the edges are formed by filing and grinding them to the bevels, shown in the enlarged figure.
Merritt's Machine for boring Angular Holes, May 24, 1864.
The holes are bored by rotary cutters; fixed, and reciprocating in a plane at right angles to the axis of the hole.
The relatively fixed auger makes a round hole, as usual; certain cutters which partake of the circular motion have also a reciprocation towards and from their axis of rotation, being projected outward and again retracted four times in a rotation, to cut out the angles left by the round auger, thus making a square hole.
