The third requisite--good faith--is not questioned by respondent, and it is sufficiently established by the record. The fourth requirement--that there be a reasonable ground to take an appeal--is indicated by the discussion in this opinion of the contention made by plaintiff. While the trial judge made conflicting statements as to his opinion of the chances of reversal of the judgment, the record shows that he did state at one point to counsel for the appellant, "You have a good chance in this appeal." And the fact that he specifically reserved the right to make an allowance of fees at the time of the final decree indicates also that he thought there might be a good ground for some award.
