Medium Staple—Usually 1 1/16 to 1 5/32 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 15/32. 
1160— MISSDEL No. 3—This variety has aU 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%; 13/16 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. 
1158—ROWDEN 40—Rowden cotton has been known for 25 years, 
but the strain 40 is a distinct improvement developed at the 
Cotton Experiment Station in Arkansas. It has a very large 
round boll, very popular with pickers. Lint outturn averages 
35%. Staple 1 1/16 inches. Early maturity, storm resistance good. 
A prolific yielder, and particularly desirable where cotton wilt 
is present, as it is highly wilt resistant. 
1165— STONEVELLE 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—It is earlier than D. P. L. 4-8, more uni¬ 
form 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. 
1164—D. P. L. No. 11—The newest strain of them all. Stands 
right at the top among the inch to inch and sixteenth cottons. 
Has everything that it takes to make a “winner”—very prolific 
yield in the field, extra earliness, easy picking qualities, storm 
resistance, uniform plant, uniform staple, unusual wilt resist¬ 
ance. And in addition, gin outturn averages 42%, sometimes 
44% is indicated. 
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 Planting 
Company plants about 20,000 acres of this seed each year. 
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.
