on it
the operation of gilling by combing it with the coarse comb.

5. Follow the gilling by the operation of _combing_, which you will do
by combing again, this time with a fine comb.

6. Pull about three inches again from the sliver. Continue to gill and
comb by section until the entire sliver has been gilled and combed.

7. Combine several strands into one and subject the one strand to a
second process of gilling to make sure that all fibers are side by
side.

8. Gently draw out this strand of combed long fibers known as top. As
you draw, spin. As you spin, wind on a lead pencil. The fineness of
the yarn depends on the amount of drawing and twisting.

9. What is the source of wool? You began with wool, covering of the
sheep's body, and after subjecting it to a series of operations you
have converted it into yarn which is ready for weaving.

10. Name the operations in order, through which raw wool passes before
it finally becomes yarn.

=Experiment 17--Difference between Woolen and Worsted Yarn=

Apparatus: Pick glass.
Materials: Sample of woolen cloth and worsted cloth.
References: _Textiles_, pages 50 and 51.

_Directions_

Take a piece of worsted fabric and separate a piece of yarn from
either the warp or filling. Do the same with a piece of woolen fabric.
Notice the appearance of each piece of yarn. Which is smoother? What
effect would friction have on the worsted yarn? the woolen yarn? Which
sample of yarn would shine and reflect the light?

=Experiment 18--Burling and Mending=

Apparatus: Chalk, scissors, dissecting pin, needle, pick glass.
Material: 4 square inches of cloth from the loom.
Reference: _Textiles_, page 71.

_Directions_

1. Cloth from the loom is far from being a finished product. It must
pass through several processes before it is finished. These processes
are known as _finishing_.

2. What is the feel of this cloth?

3. Hold the cloth to the light and look through it. Note the
