Some interesting questions of practice were raised and' discussed on the argument of this cause, but we shall not consider them, because our views are adverse to the claims of the defendants, after giving them the benefit of all exceptions taken to the original findings of the trial court of which they now seek to avail themselves. It is desirable that this litigation should come to an end, since the cause has been fully tried upon the merits and the rights of the parties conclusively determined. The judgment of the circuit court conforms to the mandate of this court, and is correct. The remittitur of this court was that the cause should be remanded with directions to the circuit court to give judgment for the plaintiff granting a perpetual injunction as prayed, and awarding him compensation for the mineral taken by the defendants from the crevice west of the 300 yards point, and appropriated to their own use. 73 *303Wis. 588. The plaintiff waived all claim for compensation for the mineral taken, as he had the undoubted right to do, and took judgment only for a perpetual injunction in accordance with the remittitur. Now7, it is objected that the court below7 should have granted the defendant’s motion, and should have found, fixed, and determined, by its findings and judgment, the 300 yards limit from the rock fence, mentioned in the complaint, so that the same could be definitely and accurately found and known by the parties, and by all persons who might become interested in the premises. This court did not direct the court below to open the case and take further evidence, nor to make any new or additional findings of fact. It had considered the case upon the evidence presented, and fully concurred in the view of the circuit court that the negotiations as to working the range west of the stone fence resulted in an agreement limiting the right of the licensees to mine and work the range to a point 300 yards west of the stone fence, and no further. There was no necessity for any further trial to determine the rights of the parties.

But it is said that this leaves the 300-yards limit from the rock fence uncertain and undetermined, because it is not clear how or from what point at the rock fence the measurement is to be made. There is no difficulty, as it seems to us, in ascertaining the point of commencement at the rock fence, and how the measurement should be made, if the pleadings and evidence are considered. In the complaint the plaintiff alleged that he was the owner in fee-simple and was in the exclusive possession of that portion of the eighty-acre tract which wras west of the point in what was known as the “ Dixon and Anthony Eange,” “ which point is nine hundred (900) feet, measured on the said range, southwesterly from the point of the intersection of the range with a certain stone fence, which was the west boundary line of the highivay named.” It was alleged that the defendants *304bad no right or license to follow and work the range on the plaintiff’s land west of that limit; but they had done so, and claimed the right to follow the range wherever it should run on the plaintiff’s land. Now, the answer practically admits these allegations to be true, with a qualification that the defendants had the right to work and follow the range wherever it might run on the plaintiff’s land, and that they were not trespassers in so doing. This, of course, clearly fixes the point of commencement of the measurement at the stone fence where the range intersects it, and the measurement is then to be made upon the range in a southwesterl}r direction, that being the general course of the range, until the 300-yards limit is reached, which is the extent of the defendants’ right to follow the range. The maxim applies, id certum■ est quod, certum reddi potest,— that is sufficiently certain which can be made certain. It is idle to say, the starting point at the fence being given, that the limit could not be certainly ascertained by measuring upon the range to the 300-yards point. But it is suggested that a different mode of measurement may be adopted, which changes the point at the western limit. In our view the correct measurement should be made along the range, or thread of the range, as the plaintiff’s counsel suggested, to the terminal point on the west.

We cannot concur in the view of defendants’ counsel, that the testimony shows that the 300-yards point might be fixed in some other way. That argument is based upon the assumption that the word “ west ” from the fence means due west, whereas the testimony, to our minds, shows that it refers to the general direction of the range, which was a westerly course; and it is perfectly plain that the right conferred or granted was to work the range in its course west for 300 yards from the fence. It was the right to follow and work the Dickson and Anthony range west of the fence that the parties negotiated about and contracted for, *305and the extent of the right must be ascertained by measuring from the initial point along the range west, until the-300-yards limit is reached. Any other mode of measurement would be, we think, unwarranted, and contrary to the-evidence as we understand it.

How as to the question as to whether the evidence-showed that the defendants had worked the range west to-the 300-yard limit when the action was commenced. That point, we think, is conclusively settled in the affirmative. The court below so found, and this finding is sustained by the overwhelming weight of testimony. It is said that this point was not much litigated on the trial, and it may not-have been. The answer, however, fairly admits that this-limit had been reached, but the admission is coupled with the claim of right to work the range wherever it should run on the plaintiff’s land. But the fact that the limit had been reached is abundantly established. The defendant John Anthony fully described in his testimony the appearance and condition of the sheet of mineral at the 300-yard point. He says: “The sheet is principally black-jack, dry-bone, and lead ore, and is from eight to eighteen inches in thickness, and some loose pieces. Its width is from sevent\f-five to one hundred feet. Four men will take out about two tons of black-jack in a day, on an average. This is the condition at the 300-yard point.” Without referring to any other testimony, as we might do, to sustain our conclusion, suffice it to say that the proof is ample, clear, and precise that the limit had been reached, and the claim now made that it had not been worked to the limit seems to be an afterthought. On the former appeal this court was entirely satisfied with the finding of the court below on that question, and there can be no doubt that the- range has been worked to the limit on the west. The testimony of the defendant John Anthony alone is'conclusive, were there nothing else in the case to establish the fact. How could he *306describe the character of the mineral and the condition of the mineral sheet at the 300-yard point, if the range had not been worked to that limit? In the face of such testimony given by one of the defendants, it is an impeachment of the intelligence of the court to claim that the range had not been worked to the 300-yard limit when the action was commenced, or that this limit was not known and had not been determined. But as the proofs show that the range has been worked to a point west of the fence, beyond which the defendants have no right to mine, a perpetual injunction restraining them from entering upon the range west of the limit and mining, was proper and right.

By the Court.— The judgment of the circuit court is affirmed.
