REGISTRATION BY MAIL
And I do hereby charge those who, through sickness, shall be unable to present themselves for registration that they apply on or before the day of registration to the County Clerk of the county where they may be for instructions as to how they may be registered by agent.
Those who expect to be absent on the day named from the counties in which they have their permanent homes may register by mail, but their mailed registration cards must reach the places in which they have their permanent homes by the day named herein. They should apply as soon as practicable to the County Clerk of the county wherein they may be for instructions as to how they may accomplish their registration by mail.
In case such persons as, through sickness or absence, may be unable to present themselves personally for registration shall be sojourning in cities of over 30,000 population, they shall apply to the City Clerk of the city wherein they may be sojourning rather than to the Clerk of the county.
The Clerks of counties and of cities of over 30,000 population, in which numerous applications from the sick and from non-residents are expected, are authorized to establish such sub-agencies and to employ and deputize such clerical force as may be necessary to accommodate these applications.
