DISSENTING OPINION.
GRAY, J.The plaintiff charged that the damages sued for were caused by defendant’s servant “leading a wild and unruly mule along the street in such 'a careless and negligent manner as to permit said mule to run into and against the plaintiff’s buggy.” While the suit was commenced in the justice court, wherein technical pleadings are not required, yet it seems to me that plaintiff charged and intended to charge that the negligence consisted in failing to exercise proper care in handling a “wild and unruly mule,” and that plaintiff did not intend to charge that the manner of handling the animal was- improper when applied to anything but a wild and *437unruly animal. The evidence showed that the animal was gentle, well broken, and was not wild or unruly, and therefore, I am of the opinion plaintiff failed to prove the negligent act alleged in his complaint.
My associates agree with me that the evidence wholly fails to show that the mule was wild and unruly, but they are of the opinion that the evidence shows it was “large and high-spirited,” and that the defendant’s servant on account thereof, was not justified in handling the mule in the ordinary manner.
While the testimony does show that the mule was large, I do not believe it does show that the servant was required to take any extra precaution in leading the animal. I believe the testimony shows that the mule was well broken and gentle. The evidence in the record on the point is as follows: “The plaintiff testified: ‘I did not notice anything alarming about those mules. Nothing more than common.’ The plaintiff’s brother testified: ‘The mule seemed to be coming along very nicely.’ ”
The defendant testified: “I had owned these mules about a year before this happened. They were well broken. I have driven them to everything. I have driven them to the carriage, to the plow and over the city. The mules were not wild, they were spirited mules.” The defendant’s servant in charge of the mules, testified: “I am-fifty years old. I have drove lots of mules and teams. I had been hauling water, to the engine witb. those mules on that day and for several days. The mules were not difficult to manage only when the steam would pop off, or the whistle blow. I would drive them right up to the engine and they would stand there. I worked for Mr. Dale on his farm. . I have known those mules-ever since he got them. They were pretty well broke mules. They were a little high lifed mules, but they were well broke for young mules.”
I can see nothing in this testimony relating to the disposition and character of the mules that required defendant’s servant in taking them along the highway, to *438exercise extra care on account thereof. The testimony does not show that they were unusually high spirited, but in the language of the witness “a little high lifed.”
On the day of the trouble defendant’s servant had been driving the team to a wagon hauling water to an engine about four miles east of the city; that when the day’s work was done, he unhitched from the wagon, leaving the harness on the mules, and got on the back of one of them, and started to the city, where the mules were kept, leading the other by an ordinary halter. While passing west on Walnut street, he met the plaintiff, who was traveling east, driving a horse hitched to a buggy. Walnut street had been paved with brick, and a ditch or excavation had been opened' on the north side of the street. The brick had been removed and piled along the street, and the dirt removed in making the excavation was also piled along the street, either next to the walk or between the ditch and the brick. The plaintiff met the servant leading the mule while passing along the part of the street so being improved. It is not claimed that the mule shied when it first came to the obstruction, and the evidence affirmatively shows that it was passing along apparently paying no attention to the obstruction, until it shied and came in contact with plaintiff’s buggy.
The contention of respondent at the trial was, that the mules should have been necked tog-ether, and that it was negligence to lead an ordinary mule along the street with a halter. The plaintiff testified: “Q. Do you know the customary manner of managing mules when they are being led over the streets A. I don’t know what- lots of people would do, but I know what I would do with them. I would neck them together so they could not spread all over the street. Q. How was he leading this mule? A. At the end of a halter rope. Q. How long was that rope? A. About five feet the best I could tell.”
The plaintiff’s brother testified: “I have had some experience in handling mules. In a place where you *439are likely to have any difficulty you neck them right up short together. No man can handle a mule of any size by halter, rein.”
The above is’ substantially all the evidence offered by the plaintiff in chief. When plaintiff closed his case, not a word of testimony had been offered to proye that the mule was a “little high-lifed.” The tidal court overruled the demurrer to the testimony, and thereby, declaring that plaintiff had made a case.
A careful reading of the opinion of my brethren will disclose that they are of the opinion that the court erred in overruling the demurrer, and that the court should, at the close of all the case, found for the defendant, had it not been for the evidence of defendant and his witness, that the mule was “high spirited.”
I have already called attention to the fact that the testimony only shows that the mule was a “little highlifed” and was really not guilty of the charge made against him in the majority opinion.
I recognize the fact that the failure of the defendant to stand on his demurrer, authorized the court to render judgment on all the evidence. I have only mentioned the action of the court on the demurrer to show that the court had a wrong idea of the case and tried it on a wrong theory of the law.
On cross-examination of the defendant, the plaintiff sought to show that the mule was given five feet of rope, and that it was error to give it more than four. The evidence of the witness was, that four feet would be all right, and that five or six feet would be too much. There was no testimony that the mule was given five feet of rope. The witnesses testified that the halter strap was five or six feet long. This is no evidence that it was more than five. The evidence shows that the man had hold of the rope at or near the end, and therefore, if we are to measure plaintiff’s testimony by technical rules, it wholly fails to show that the mule was given an improper amount of rope..
*440I fully agree with the majority opinion that the so-called expert testimony should he wholly ignored. The witnesses did not attempt to say what was proper under the particular circumstances of the case. And the testimony of plaintiff and his witness that a man in taking a domestic animal, like a mule or a horse along a street, must neck it to another animal, and must not attempt to handle it with a halter, is so ridiculous and absurd and contrary to the common knowledge of every one, that it should be entirely rejected. And as said by the Supreme Court of Wisconsin in Baxter v. Railroad, 80 N. W. 644: “Mere opinion evidence, at best, is to be received and scrutinized with the greatest care. It is, ordinarily, the most uncertain kind of evidence that can be produced, and falls to the ground as utterly worthless when inconsistent with common sense. The jury must pass upon the probabilities, and unless the opinion relied on is within the scope of reason and common sense, it should not be regarded at all.” And as said by our own Supreme court, in Weltmer v. Bishop 171 Mo. 110, 71 S. W. 167. “Courts are not such slaves to the forms of proceedure as to surrender their own intelligence to an array of witnesses testifying to an impossibility. They are not required to give credence to a statement that would falsify well-known laws of nature though a cloud of witnesses swear to it.”
The leading of domestic animals along a street by halters has been the universal practice so long that courts will not regard testimony of so-called experts to the contrary. In Post v. Ry. Co. 121 Mo. App. 562, 97 S. W. 283, the plaintiff, while cutting weeds with a scythe on the right of way of defendant, was injured by the scythe failing to cut a weed, and pulling it into his face. The work was performed on the side of a hill, and the plaintiff claimed a scythe was an unsuitable tool to use to cut weeds in such a place. In sustaining a demurrer to his testimony, the court said: “A scythe is a simple tool, used by mankind from remote ages to the *441present for the cutting of grass, grain and weeds, and it would be absurd to treat as an issue of fact the propriety of its use for such purposes on any hind of ground where the mower could stand. The nse of snch simple, universal tools, being a matter of common knowledge about which reasonable minds do not differ, are a subject óf which courts may take judicial knowledge.”
The fact that the so-called expert testimony went in without objection in no wise adds to its weight or makes it sufficient. [St. Louis v. Roche, 128 Mo. 541, 31 S. W. 915; Boggs v. Laundry Co., 171 Mo. 282, 70 S. W. 818; Thompson on Trials, sec. 691.]
The real question in this case is :- Is sc defendant liable because his servant rode one mule along the street, and led another by an ordinary halter, simply because he met a buggy in a portion of the street that was being improved, and the mule that was being led shied at the improvement and came in contact with plaintiff’s buggy. The evidence wholly failing to show that the mule had any bad habits, or was of a bad disposition, or that it ever shied at anything of the bind before, notwithstanding it had been used for some time upon the streets of a city.
A case on all-fours was decided by the Supreme Court of Rhode Island, and is reported in the 56 Atl. 677. In that case the court said: “The plaintiff was riding in a buggy along the street in the city of Providence. At the same time a servant of the defendant in charge of two horses, riding one and leading the other by a halter, was proceeding along the street. When the plaintiff drove alongside the horses, the led horse suddenly wheeled and kicked the buggy, throwing the plaintiff out and injuring him. The decision of the question whether a domestic animal is or is not rightfully in the place where it inflicts an injury complained of is determinative as to the necessity of proof of knowledge, on the part of the owner of a vicious propensity of the animal. The leading of horses in the street is an every*442day occurrence. It is tbe common practice of ordinarily careful and prudent men. The horse, being in charge of an attendant and led by a halter, was rightfully in the street. There was no evidence that he had ever before shown any vicious propensity or had been known to kick. Under such circumstances, the defendant in the absence of testimony showing negligence in the manage» ment of the horse while in the street would not be liable.”
My brethren say: “There should be some limit to the amount of rope given a Missouri mule in a public street of a. city is self-evident.” With this statement I fully agree without limiting its applicaion to a “Mis» souri” mule. But my contention is, that the undisputed evidence in this case shows that the mule was led by a halter strap of the ordinary length. If there had been any testimony that the mule was wild and unruly, and that defendant’s servant on account thereof might have expected trouble, a different case would be presented. The servant was doing nothing except leading the animal along the street in the same manner it has been led for a time so long “that the memory of man runneth not to the contrary.” And our courts hold under such circumstances there is nó negligence. [Wendall v. Railroad, 100 Mo. App. 556, 75 S. W. 689.]
It seems to me that plaintiff wholly failed to make a case, and that we should follow the 'decision of the Kansas City Court of Appeals in Post v. Railway, supra, and hold that the use of a halter to lead a domestic animal along the street, is such a common practice that it is a matter about which reasonable minds do not differ.
There is another reason why, in my judgment, the judgment should be reversed. There is not a word of testimony in the case tending to prove that leading the mule by a halter strap five feet long, caused the damage. The burden was upon the plaintiff, not only to show that his buggy was damaged and the defendant was negligent, but to show by the preponderance of the evidence *443that his damages would not have been suffered, except by the negligent act of the defendant. [Brown v. Railroad, 65 Mo. App. 162; Warner v. Railroad, 178 Mo. 125, 77 S. W. 67; Harper v. Terminal Co. 187 Mo. 575, 86 S. W. 99; Breen v. Cooperage Co., 50 Mo. App. 202.]
It is apparent that in order to prove that the damage was caused by the servant leading the mule by five feet, of rope instead of four, the distance from the man riding the other mule to the buggy, must be determined. If the mule the servant was riding and the buggy were only six or seven feet apart, then we know from our knowledge of the length of a large mule, that it could have gotten its foot behind the front part of the front wheel of the plaintiff’s bitggy, even if it had been “necked to the other mule.”
My associates say on this point: “The evidence does not clearly show the distance between the mule and plaintiff’s buggy at the time the mule scared.” This is true if we reject the plaintiff’s testimony on that point. On cross-examination of the defendant’s servant, he testified that the buggy was about two feet from him. My associates dispose of this testimony by stating that it was a voluntary statement on the part of the witness and was not responsive to any question asked him. With all due respect to them, the record does not bear out the statement. The testimony appears in narrative form with but very few of the questions shown. The testimony of the witness appears at the end of a pargraph and the question that elicited the answer is not given. But if the testimony is stricken it only leaves plaintiff’s case in a worse condition. Without this testimony, the whole matter is left to conjecture and speculation.
The plainiff testified as fellows: “They kind of scared sideways, of course. If they hadn’t they wouldn’t have gotten on my wheel.” If this testimony is accepted as true, then both mules shied toward plaintiff, and in that case, the length of a halter strap might have nothing to do in causing the damage.
*444The evidence does not show the width of the street or how much of the street was occupied by the obstruction. The plaintiff speaks of meeting defendant’s servant “in a crowded place.” The plaintiff’s brother testified: “The mule kind of shied off a little bit. It came up sideways like and just whipped around over the buggy.” Upon what theory it can be said that this testimony shows that if the mule had been led by a rope four feet long, the accident would not have happened, I must confess I am unable to understand. I am also unable to see the logic of my brethren on this point stated by them as follows: “It is common knowledge that there is not much space between the shaft and the wheel of a buggy; hence if the mule had been held a little closer in by its master, its leg would not have gotten between the shaft and the wheel of the buggy, when it shied off sideways and whipped around.”
If the evidence showed that the distance between the men riding the mule and the wheel of the buggy, was so great, that when the mule had pulled away from its master as far as the halter strap would permit, and then whipped around, it was just able to reach the wheel of the buggy, there would be some weight in their statement. But if the mule the servant was riding was eight or nine feet from the buggy, and was» being led by a halter strap two feet long, and it shied away from its master as far as it could and whipped around, its own length added to the two feet of halter strap would have reached the buggy.
I understand that questions of fact are for the trial-court in actions at law. But I also understand that it is the right and duty of the appellate court to reverse a judgment that is without substantial evidence to sustain it. [Milan v. Freeman, 186 Mo. App. 1. c. 117, 117 S. W. 644; Bates Co. Bank v. Railroad, 98 Mo. App. 330, 73 S. W. 286; Spiro v. Transit Co., 102 Mo. App. 250; 76 S. W. 684; Haviland v. Railroad, 172 Mo. 106, 72 S. W. 515.]
*445Wlien the evidence leaves the question whether plaintiff’s injury was the result of the negligent act of the defendant to mere conjecture, the trial court has no right to render a judgment against the defendant. As said by Judge Marshall in Warner v. Railroad, supra: “If the injury may have resulted from one of two causes, for one of which and not the other, the defendant is liable, the plaintiff must show with reasonable certainty that the cause for which the defendant is liable produced the result, and if the evidence leaves it to conjecture, the plaintiff must fail in his action.”
While the amount involved is small, the legal principles announced in the majority opinion, are far reaching. If this defendant is liable for the damage to plaintiff’s buggy, then farmers and other persons passing through the country, must cease to follow the long accustomed practice of leading horses and mules behind their wagons by an ordinary halter strap, while passing along the highway. In any event, the opinion of the majority makes it a question for the jury in every case where a domestic animal is a little high lifed” and shies to one side and causes damage while beind led by an ordinary halter. And this is true where the animal is well broken and the evidence fails to show that it had ever shied at an object before.
I believe the plaintiff failed to make a case, and that the judgment should be reversed. I further believe that the correct rule is declared by the Kansas City Court of Appeals in Post v. Railway, supra, and that the opinion of my associates in this case is in conflict with that case, and I therefore ask that the cause be transferred to the Supreme Court.
