PILLAR, in the manège, is the centre of the ring, or
manège-ground, round which a horse turns, whether
there be a pillar in it or not. Besides this, there are
pillars on the circumference or sides of the manège-
ground, placed at certain distances, by two and two,
from whence they are called the two pillars, to dis-
tinguish them from that of the centre. The use of the pil-
lar in the centre is for regulating the extent of ground,
that the manège upon the volts may be performed with
method and justness, and that they may work in a
square, by rule and measure, upon the four lines of the
volts; and also to break unruly high-mettled horses,
without endangering the rider. The two pillars are
placed at the distance of two or three paces one from the
other; and the horse is put between those, to teach him
to rise before and yerk out behind, and put himself upon
raised airs, &c. either by the aids or chastisements.
