with mosquito netting or cheese cloth, and the water poured through
this and allowed to drain off.

Excreta is the most deadly form of waste, and too much care cannot be
exercised in disposing of it. Impress upon every man that he must
cover completely with dirt all excreta so that flies may not have a
chance to approach it.

For short stops and while working in the field "straddle," latrines
are the best. These are shallow trenches the width of a shovel, about
12 inches wide, and several feet in length. For long stops a deep
latrine is dug of the following dimensions: 2 feet wide, 6 feet deep
by 15 feet long. Two posts with crotches, driven at the ends of this
trench, supporting a substantial pole to make a seat * * * for
convenience a hand rail placed in front of this improvised seat will
add to the comfort of the men.

A more permanent latrine is made by covering the pit with a wooden
box, in the top of which are cut holes of the necessary diameter. To
these holes should be fitted spring covers which will shut down
tightly. A wooden frame boarded around this arrangement makes a
satisfactory enclosure.

A urinal made of two long boards joined together to form a V-shaped
trough and drained by a pipe into the pit completes the whole. A pitch
sufficient for rapid drainage should be given the urinal trough.

When necessary to utilize separate urinals, a hole filled with stone
and sprinkled daily with quicklime is sufficient for short periods. At
night there should be a galvanized iron can placed in each company
