Thus in 1837 the Twin-seed or Okra cotton was in vogue, selling at many places for five dollars a quart.

In 1839 this was eclipsed by the Alvarado strain, which its sponsors computed from an instance of one heavily fruited stalk nine feet high and others not so prodigious, might yield three thousand pounds per acre.[32] Single Alvarado seeds were sold at fifty cents each, or a bushel might be had at $160.

In the succeeding years Vick's Hundred Seed, Brown's, Pitt's, Prolific, Sugar Loaf, Guatemala, Cluster, Hogan's, Banana, Pomegranate, Dean, Multibolus, Mammoth, Mastodon and many others competed for attention and sale.

Some proved worth while either in increasing the yield, or in producing larger bolls and thereby speeding the harvest, or in reducing the proportionate weight of the seed and increasing that of the lint; but the test of planting proved most of them to be merely commonplace and not worth the cost of carriage.

Extreme prices for seed of any strain were of course obtainable only for the first year or two; and the temptation to make fraudulent announcement of a wonder-working new type was not always resisted.
