If, therefore, there were no more in the case, the appellants would be entitled to judgment. But the learned Judge also found that in 1910 the outlet of the drain was very seriously obstructed by a compacted mass of material, which, according to the evidence, diminished the capacity of the outlet by about one-half. He did not make any express finding as to the existence of this obstruction at the times when the floodings complained of occurred. But upon the evidence there was reason to believe that the accumulation of the mass had been going on for some years, and it appeared that the defendants' officers had since 1905, when a complaint was first made on the subject, given instructions to clear out the drain periodically. There was, therefore, evidence fit for the consideration of a jury to show that the floodings complained of were occasioned in part, if not altogether, by this obstruction. If the case had been tried with a jury who had been directed to the effect of the learned Judge's judgment, there must have been a new trial. To grant a new trial in the present case, where the damages awarded were only £100, would be oppressive. On the other hand, it is undesirable for this Court, or, indeed, any Court of appeal, to exercise the functions of a Court of first instance in determining facts which have not been found by the Court appealed from. The parties have, however, agreed that if the Court is of opinion that upon the evidence the injuries to the plaintiff were caused in part by the obstruction I have described, but that the defendants were not liable for damage which would have accrued if there had been no such obstruction, judgment shall be given upon that footing without a new trial.
