FACING A BATTERY TO THE REAR ON A NARROW ROAD.
All the carriages are moved close to one side of the road, and the pieces and caissons unlimbered and brought about; the limbers then take their places in front of their carriages by an about, and the carriages are limbered up; if there be not room for the limbers to execute an about, the horses are taken out.
If the road be so narrow that the limbers cannot pass the carriages, the trails of the pieces and the stocks of the caissons are carried around until perpendicular to the road, and are then placed against the bank, the wheels being run close to it; on an embankment, or a road with ditches on each side, the carriages are run as close to the edge as possible, the wheels chocked or locked, and the trails and stocks held up while the limbers pass.
THE ODOMETER.
The odometer registers the number of revolutions of the wheel to which it is attached. The distance measured by the odometer is not exact, owing to the slip of the wheel.
To Read the Odometer.—Lift the reading-circle from its box and note the number on the inner wheel to the left of the zero; this will be the first two figures of the reading, and the number on the outer wheel to the left of the pointer will be the next two.
To Measure a Distance with the Odometer.—Tie the case by its straps to a spoke close to the hub of a hind wheel of any vehicle attached to the command. Upon starting read the odometer and record the reading. At the end of the course again record the odometer-reading. The difference between the two readings multiplied by the circumference of the wheel will give the distance passed over. And in general, the difference between any two readings, multiplied by the circumference of the wheel which bears it will give the development of the path traversed by the wheel between the points at which the readings were taken.
CAMPS AND CAMPING
SELECTION OF CAMPS.
Avoid camping or bivouacking in graveyards. Get as far to windward of them as possible.
