Medium Staple—Usually 1 1/16 to 1 5/32 Inches 
Long- Staple—Usually 1 5/32 to 1 5/16 Inches 
1156—DELFOS No. 531—Early maturing, quite similar to Missdel 
No. 4. Both are developments from the original Delfos 6102. It 
is one of the most prolific bearers ever developed, and one of 
the most successful cottons under boll weevil conditions. Foliage 
is light, plant is medium, vigorous and spreading. Bolls 75 to 80 
to the pound. Lint percentage 32 to 34. Lint length on valley 
land 1 5/32 to 1 7/32, and on hill land 1 3/32 to 1 5/32. 
1160— MISSDEL No. 3—This variety has all the good character¬ 
istics of the Missdel No. 1. Type, semi-dwarf, light foliage; big 
boll, 60 to 65 per pound; lint 32% to 34%; 1 3/16 to 11/4 inches 
full. Maturity, the earliest of all staples of equal length. Storm 
resistance good. 
1161— MISSDEL No. 4—Type, dwarf and very hardy. The boll is 
not so large as No. 3, about 70 to 75 to the pound, storm resist¬ 
ance is good, its lint percentage on delta land runs 34 to 36 
(better than thirds itself). And on hill land it has run 36% to 
39%. Length of staple on delta soil 11/8 to 13/16 inches and in 
hill land 1 inch to 1 3/32 inches. The picking qualities have been 
much improved over Delfos 6102 from which it was developed. 
COTTONSEED MIXING INCREASED BY MODERN 
GIN EQUIPMENT 
The information and cut below were copied from U. S. Depart¬ 
ment of Agriculture circular No. 205 by W. W. Ballard and C. B. 
Doyle. You can get one of these circulars by addressing Bureau 
of Plant Industry, Washington, D. C. 
It is generally known that the seed is mixed when one variety 
of cotton follows another at the public gin, but the extent of 
the mixture was not appreciated until a method of testing was 
developed and a careful experiment made at Greenville, Texas, 
in 1914. The results of that test showed that cottonseed was 
mixed at the public gins far more than was generally realized 
and emphasized the necessity for co-operation between the 
farmers and ginners if supplies of pure seed for planting were 
to be maintained. 
But the test of 1914 does not show the full extent of mixing, 
which has increased notably in recent years with the wider use 
of modern gin equipment. The general tendency in the con¬ 
struction of gin plants has been toward more and larger gin 
stands, in order to make more efficient use of the power and 
other equipment and to speed up the handling of the seed cotton. 
These are desirable aims, but the change results incidentally in 
a further increase in the mixing of seed, which is already a 
serious menace to the preservation of superior varieties of cotton. 
Since each gin machine, or “stand,” has a roll box in front of 
its saws, the large ginning establishments increase the extent of 
the mixing in proportion to the number of gin stands. 
This picture and above wording explain why so many of our 
best farmers buy pure bred cottonseed every two or three years. 
1164— STONEVILLE No. 1—Very early maturing, small stalk, 
extra large bolls, 55 to 65 to pound. Easy to pick, but good storm 
resistance, lint percentage 33% to 36%, staple 11/16 to 11/8 inches. 
1165— STONEVILLE No. 2—This is a more vigorous and spread¬ 
ing plant than No. 1, but also a very early cotton. Bolls not quite 
so large but still large. Picks well, and has very good storm 
resistance. Lint percentage 34% to 36%, and length of staple 
1 1/32 to 1 3/32 usually. 
1166— STONEVILLE No. 3—Very prolific, staple 1 1/32 to 1 1/8, 
lint turnout 37% to 40%, opens well, picks good, bolls around 
65 to 75 to a pound, storm resistance good, open, vigorous stalk. 
1162— D. P. L. No. 10—This is the best of all the D. P. L. strains. 
It is earlier than D. P. L. 4-8, more uniform in type, and more 
productive in the field. Turns out well at the gin, 36% to 38%, 
and we have heard of 40% turnout. It pulls 1 inch to 1 1/16 
inches. Picking qualities are excellent and the storm resistance 
is extra good. Bolls are large, 65 to 75 to the pound. The plant 
is vigorous and spreading. 
1163— WILSON BIG BOLL—Fruits early, with a strong, wiry 
staple easy to pick; staple 1 inch to 1 1/16 inches, bringing a 
premium for quality grade. Big five lock bolls bunched like 
grapes all over the plant, blooms early, bolls open early, staple 
in uniform gin turnout 36% to 40% lint. The Wilson Ranting 
Company plants about 20,000 acres of this seed each year. 
CLEANING COTTON SEED 
A germination test of cotton seed is not a real test for planting 
seed. Every stalk of cotton bears some poor seed. No matter 
how prolific, some of the seed are weakling, and may possibly 
germinate, but will never produce fruit-bearing plants. I have 
before me a photographic cut showing two stalks of cotton 
grown four feet apart; one has 105 full sized bolls, and the other 
has four dwarfed bolls, the difference is due solely to seed 
which produced this cotton. While seed were of same variety 
and may have been grown on same stalk, one was fully matured, 
plump and heavy, while the other was light and of low vitality. 
Any field of cotton will demonstrate, the above is not THEORY— 
BUT FACT. Cleaning seed is not to supersede the plant breeder, 
but to perform an operation for which he has no facilities. Buy 
seed which have been properly cleaned and graded. If planting 
your home grown seed, arrange a home made cleaner and sepa¬ 
rator to take out the locks, bolls and other foreign matter which 
stops up your planter and causes long skips in your cotton rows 
—these skips cost the cotton planters of the South thousands of 
dollars each year. We rec'lean our cotton seed before shipping 
to take out the bolls, locks, sand, trash, light seed and wild weed 
seed. This operation costs us $3.00 a ton for cleaning and loses 
about 10% of the seed.
