oscar,I want to say

oscar,I want to say that the rise in slave prices stimulated the development of the mechanical cotton picker which was invented in Memphis in the 1850s, but world cotton prices collapsed in the late nineteenth century following the abolition of slavery (impoverished sharecroppers grew more cotton), and its technological development was stalled until the 19gs./1930s0Ri2ht now, I am more focused on the West Indies, where cotton was dwarfed by sugar, but by the time I write the book I will definitively answer the question.
