ated.

B.--A "BAGGING" made from comparatively fine single warp arranged in
pairs and then termed "double warp." The weft is thick, and the
weave is also plain.

T.--A "TARPAULING" made from yarns similar to those in bagging,
although there is a much wider range in the thickness of the weft.
It is a much finer cloth than the typical bagging, but otherwise the
structures are identical.

S.--A striped "SACKING" made from comparatively fine warp yarns,
usually double as in bagging, but occasionally single, with medium
or thick weft interwoven in 3-leaf or 4-leaf twill order. The weaves
are shown in Fig. 33.

C.--One type of "CARPET" cloth made exclusively from two-ply or
two-fold coloured warp yarns, and thick black single weft yarns. The
threads and picks are interwoven in two up, two down twill, directed
to right and then to left, and thus forming a herring-bone pattern,
or arrow-head pattern.

P.-An uncut pile fabric known as "BRUSSELLETTE." The figuring warp
is composed of dyed and printed yarns mixed to form an indefinite
pattern, and works in conjunction with a ground warp and weft. The
weave is again plain, although the structure of the fabric is quite
different from the other plain cloths illustrated. The cloth is
reversible, the two sides being similar structure but differing
slightly in colour ornamentation.

As already indicated, there are several degrees of fineness or
coarseness in all the groups, particularly in the types marked H, B,
T and S. The structure or weave in all varieties of any one group is
constant and as stated.

All the weaves are illustrated in the usual technical manner in Fig.
33, and the relation between the simplest of these weaves and the
yarns of the cloth is illustrated in Fig. 34. In Fig. 33, the unit
weaves in A, B, C, D, E and F are shown in solid squares, while the
repetitions of the units in each case are represented by the dots.

CLOTH]

A is the plain weave, 16 units shown, and used for fabrics H and P,
Fig. 32.

B is the double warp plain wave, 8 units shown, and shows the method
of interlacing the yarns h patterns B and T, Fig. 32. When the warp
is made double as indicated in weave _B_, the effect in the cloth
can be produced by using the mechanical arrangements employed for
weave
