Although this was written in a 1920 letter, the letter was not publicly published until 1970.
At the time, many scientists and intellectuals thought erroneously—see related quotations—that hybrids would be inferior humans. What makes this quotation memorable is that although he acknowledged that empirically, mixed race people (human hybrids) were inferior, of offered an explanation that did not violate sound genetic science as most others did. He concluded that sociologically whites and black who would intermarry or interbreed would generally not come from the top echelons of either race. Therefore the lower half of each race would more likely produce offspring and provide them with an environment that was not optimum so genetics and nurture worked against the mulatto. At the time that may well have been so, and perhaps until recently it was so forth the majority of crossbreeds of many societies.

So he wrote his own appendix to the report which was embarrassing to some of the administrators and contractors but was really appreciated by almost all of the scientists and engineers.
