he watering, they are _bent with an angle, or elbow_, that
is in stead of lying, or being bent _round_ the threads, as in the third
Figure, a, a, a, a, a, are about b, b, b (b, b, b representing the ends, as
'twere, of the cross threads, they are bent about) they are creas'd on the
top of those threads, with an _angle_, as in the fourth Figure, and that
with all imaginable variety; so that, whereas before they reflected the
light onely from one point of the round surface, as about c, c, c, they now
when water'd, reflect the beams from more then half the whole surface, as
de, de, de, and in other postures they return no reflections at all from
those surfaces. Hence in one posture they compose the brighter parts of the
waves, in another the darker. And these reflections are also varied,
according as the particular parts are variously bent. The reason of which
creasing we shall next examine; and here we must fetch our information from
the Mechanism or manner of proceeding in this operation; which, as I have
been inform'd, is no other then this.

They double all the Stuff that is to be water'd, that is, they crease it
just through the middle of it, the whole length of the piece, leaving the
right side of the Stuff inward, and placing the two edges, or silvages just
upon one another, and, as near as they can, place the wale so in the
doubling of it, that the wale of the one side may lie very near parallel,
or even with the wale of the other; for the nearer that posture they lie,
the greater will the watering appear; and the more obliquely, or across to
each other they lie, the smaller are the waves. Their way for folding it
for a great wale is thus: they take a Pin, and begin at one side of the
piece in any wale, and so moving it towards the other side, thereby direct
their hands to the opposite ends of the wale, and then, as near as they
can, place the two opposite ends of the same wale together, and so double,
or fold the whole piece, repeating this enquiry with a Pin at every yard or
two's distance through the whole length; then they sprinkle it with water,
and fold it the longways, placing between every fold a piece of Pastboard,
by which means all the wrong side of the water'd Stuff becomes flat, and
with little wales, and the wales on the other side become the more
protuberant; whence the creasings or angular bendings of the wales become
the more perspicuous. Having folded it in this manner, they place it with
an interja
