Read it through once

The association had a good bank account now, and was very strong. There was no longer an outsider. A by-law was added forbidding the reception of any more cubs or apprentices for five years; after which time a limited number would be taken, not by individuals, but by the association, upon these terms: the applicant must not be less than eighteen years old, and of respectable family and good character; he must pass an examination as to education, pay a thousand dollars in advance for the privilege of becoming an apprentice, and must remain under the commands of the association until a great part of the membership (more than half, I think) should be willing to sign his application for a pilot's license.
