shall be constituted as follows:
_First_: The bankers' council of each commercial zone shall elect a
member to the board of the American Reserve Bank. The commercial zones
bearing the odd numbers shall elect bankers and the commercial zones
bearing the even numbers shall elect business men, and every seven
years thereafter the bankers' council of the respective zones shall
alternately elect a banker or a business man, so that the elective
members of the board of directors of the American Reserve Bank shall
always be composed of an equal number of bankers and business men.
_Second_: The term of service shall be seven years; but the terms of
service of the first elected board shall be for one, two, three, four,
five, six, and seven years, respectively; that is, the board shall
arrange itself into seven groups, each composed of two or more bankers
and two or more business men, and thereupon the seven groups shall
determine by lot how long each group shall serve.
