CURRENT FIELD ARTILLERY NOTES
to place the guns in order that the shots will clear the crest when laid at
the range of the target:
Being at the selected position of the guns, the observer places the
instrument before the eye as in measuring the angle of site. He marks a
point on the terrain, A (see Fig. 3) having an angle of site equal to that
of the target, displaces before the eye in such manner the instrument
that the point A will be seen to the left of the instrument and brings the
zero graduation on the left side (graduation in range) to the height of the
point A, then reads on this left hand scale the distance to the summit of
the crest (see Fig. 4).
Fig. 3. Fig. 4.
The graduations in range can be employed in all cases as explained
above, where the crest is distant at least 300 yards.
(c) To measure deflections or angular deviations: Hold the
instrument by the button in the right hand and place it horizontally
before the right eye, supporting it against the cheek at the base of the
nose in such a manner that by looking through the large central window
the deflection scale can be read on the inside, and by looking over or
under the instrument the required graduation of the scale can be brought
into coincidence with the aiming point or target and the deflection in
mils read to the required point.
The scale is graduated into 533 mils, conforming to the sight
graduation on the French 75 mm. piece which is divided into four
quadrants each numbered from 1 to 16 hundred.
