History of Delfos Cottons 
In 1904, Dr. D. A. Saunders of the United States Department of Ag- 
riculure crossed Sunflower and Triumph cottons. Foster cotton was lat¬ 
er developed by the Department, from this cross. A selection made in a 
field of Foster in 1911, at the Delta Experiment Station, by E. C. Ewing 
resulted in Foster 120. 
In 1916, Dr. H. B. Brown made selections at the Delta Station in a field 
of Foster 120, and two of these selections—Nos. 631 and 6102—later were 
designated as Delfos 631, and Delfos 6102 respectively. Both were early. 
The 631 strain produced a rather tall rangy plant with big boll, big 
wooly seed, and had longer lint than 6102. 
The 6102 strain was dwarfy, spreading, small boll and seed, and very 
prolific. 
The Stoneville Pedigreed Seed Co., since its beginning, has continued 
to work with the Delfos strains. At the present time all the Delfos strains 
we are breeding are descended from the original 6102 type, though some 
of them differ from the original in one or more characters. 
The following popular strains of Delfos were bred by the Stoneville 
Pedigreed Seed Co. and they now have seed of these strains avaiable for 
sale in quanity except No. 531, which has been discontinued in favor of 
the 531-A and 531-B.

The men who develop new and better strains of cotton are public 
benefactors and deserve your seed business. The Seed Breeders are in po¬ 
sition to supply you with the very best seed of their strains at a reason¬ 
able price. WHY BUY CHEAPER SEED AND TAKE A CHANCE?
