The immense number of rings that must have been produced for members of the largest societies becomes apparent when we consider that the Independent Order of Odd Fellows, whose English foundation dates back to about 1745, now has a membership of over 1,500,000, in the United States and more than 160,000 in other countries. To this must be added the membership of the Daughters of Rebekah, a coördinate body of women numbering about 700,000. Another society, the Knights of Pythias, though of comparatively recent organization, having been founded in Washington, D. C., in 1864, has over 700,000 members in the United States and Canada. This order has a branch exclusively for the colored race, denominated the Knights of Pythias of North and South America, Europe, Asia and Africa; its members number 50,000. The Benevolent and Protective Order of Elks counts 410,000 members in 1309 lodges and the Knights of Columbus, a fraternal and benevolent society founded in New Haven in 1882, had, on July 1, 1914, 326,858 members. The membership of the Greek-letter fraternities of the universities and colleges in the United States is enormous. In 1914 there were 38 leading fraternities distributed in 1228 active chapters and counting 2,656,817 members, with 979 fraternity houses. The oldest Greek-letter society, Phi Beta Kappa, was organized at William and Mary College, Virginia, in 1776; Kappa Alpha was founded at Union College, in 1827, this being the first fraternity to be organized according to the system at present prevailing. The first sorority was Kappa Alpha Theta, established at De Pauw in 1870. The sororities now have about 50,000 members in 395 chapters. A gem representing one of the States is often set in a talismanic ring. The following is a list of the stones of the various States in the United States,--a precious or semi-precious stone having been found in every State:
