“Like letting spiders live because they eat mosquitoes,
Clary thought. "So they're good enough to let live, good enough to make your food for you, good enough to flirt with-but not really good enough? I mean, not as good as people.”

Attributed, for example, by http://web.archive.org/20090806185021/www.international.ucla.edu/burkle/article.asp?parentid=2198, which contains a common version of the story, where Ferguson says this while holding a bible and defending her objection to the teaching of Spanish in Texas public schools
According to http://itre.cis.upenn.edu/~myl/languagelog/archives/003084.html, a variation on this quote is reported in the New York Times on May 23, 1881, but no record of Ferguson having said this, or anything like it, could be found
This quote and variations on it are often frequently attributed to others; one story, usually heard outside the United States, has an unnamed "U.S. congressman" saying it in a television interview; for example, see http://ontrapranur.blogspot.com/2008/05/if-english-was-good-enough-for-jesus.html
