Thirty-two pinches of ottoln were taken at random from each
ot'the Qpinning test .ot and e ompnited into a hand-made sliver
n aseordaneo with standard procedure. These slivers were used for
te fiber teats. Fiber teats were performed, in accordance with
the standard procedures of the laboratories, under controlled atmos-
phorio conditions at 65 percent relative humidity and 70 F. Fiber
tests include determination of length, uniformity ratio, tensile
strength, fineness in tirms of weight per inch of fiber, and matur-
ity in terms of percentage of thick-walled fibers.


The spinning tests were performed by a technique, developed
in the laboratories of the Cotton Branch, for testing small samples.
Each test sample was passed through the following standard type tex-
tile machines

In comparing those average grade figures with the pie
eard waste data reported in column 3 of table 2, it should be under-
stood that variations from the averages for indiyidual samples are
attributable to the nature of the extraneous material present in
cotton, to the .oharaoteristios oft the fiber, or to whether the i
designation was low because of poor color or preparation.

The staple-length designation of a sample of cotton as
mined by custonary classing methods, indicates the length of a
"typical portion" of the fibers in the sample. Uniformity of
length, as well as other fiber properties, probably influences t
some extent the olasser's selection of the "typ oal portion" o;
fibers on which the staple-length designation is based. In genosa,
there is a fairly close relationship between the staple length a
designated by the claeser and the fineness and strength of the ya
that can be manufactured from the cotton. These relationships, bh-
ever, are influenced by other fiber properties, the measurements r
which are discussed on pages 3 5.
