Who may appeal as pauper. Procedure on application for admission of appeal

Any person entitled to prefer an appeal, who is unable to pay the fee required for the memorandum of appeal, may present an application accompanied by a memorandum of appeal, and may be allowed to appeal as a pauper, subject, in all matters, including the presentation of such application, to the provisions relating to suits by paupers, in so far as those provisions are applicable:

Provided that the Court shall reject the application unless, upon a perusal thereof and of the judgment and decree appealed from, it sees reason to think that the decree is contrary to law or to some usage having the force of law, or is otherwise erroneous or unjust.
