Again quoting from the 1911 book:
"An outward indication of an abnormal, unhealthy and unphysiological life is a small waist, whether abnormally natural, or caused by the wearing of corsets; avoid them as you would the plagues of Egypt, for they encompass sickness, premature decay and death. Such women are not capable of pure love, or right judgment, or, what is so essentially important, giving birth to healthy, vigorous offspring. Their very souls are malformed in harmony with their bodies. Some men admire small waists, but they are men who possess but a modicum of brains-or, if otherwise, they may admire, but they carefully guard against ever marrying them. If it is your desire to secure a wife that will be free from eternal nervousness, headache, pains, ill temper, and especially if you aim to have children that will not be sickly and short-lived, I pray you avoid marrying a woman with a small waist. I consider this matter of large waists such a necessity, in a woman who aspires to be a wife and mother, that, to impress it more positively on the minds of all men in search of wives, I will again repeat, in large letters, SHUN SMALL WAISTS, and act on the rule of "NATURAL WAISTS or no wives.” "
