Opinion by
This appeal presents a very narrow issue; in an eminent domain action, in which no evidence was introduced as to the normal commercial rate of interest during the period of detention, should the trial court have instructed the jury to award detention money 1 *168 (1) at the rate of 6% per annum or (2) at mvy rate the jury saw fit, not exceeding 6% per annum?
The Commonwealth of Pennsylvania in the exercise of its power of eminent domain condemned appellee’s property for highway purposes. A jury awarded verdicts for the freehold owner of $25,575 and for the leasehold owner of $12,834. After the appellant moved for a new trial the parties then stipulated in substance: (1) that appellant would immediately pay $22,000 to the freehold owner and $11,040 to the leasehold owner; (2) that payment of the balance of the jury’s award ($5,369) — the amount of the detention money — would depend upon the adjudication of the propriety of the trial court’s jury instruction on the subject of detention money.
On this subject the trial court charged: “Now, in addition to the fair market value of the property at the time of the condemnation, plaintiffs are also entitled to receive money damages to compensate them for the detention of their money unless you would find their claims for damages are exorbitant. Now, this additional sum is called detention money. It is not strictly speaking interest. It is, however, computed as interest. It is to be presumed that the interest during the period of detention was the 6%. We have no evidence to the contrary. Therefore, any sum awarded the plaintiffs for the fair market value of the various interest involved will be increased by a sum based on 6% interest for 32% months which is the period of detention, and which has been agreed 2 upon by counsel for the plaintiffs and counsel for the Commonwealth. This interest is simple interest, and is not to be compounded.”
*169 The appellant presented a point for charge which the trial court refused, said point reading : “If you decide to allow the plaintiffs detention money, you may allow it at any rate you see fit, not exceeding six percent per annum.”
An examination of this portion of the court’s charge indicates the jury was instructed that, unless appellees’ claims for damages were found to be exorbitant, appellees were entitled to detention money computed as interest and, in the absence of any evidence .as to the ordinary commercial rate during the detention period, the jury were to presume such rate to be 6%. and, therefore, any sum awarded to the appellees as the fair market value of their property would be increased by a sum based on 6% for the period of detention. 3
Detention money in eminent domain cases is not awarded as a matter of right but only as the circumstances of the particular case dictate that compensation. for delay in payment, should be made. 4 , It is not disputed that the instant case properly called for the award of detention money. 5

The court below relied principally on the language of this Court in
Whitcomb v. Philadelphia,
The
Whitcomb
rule has been cited frequently with approval by this Court:
Pennsylvania Co. for Insurances on Lives v. Philadelphia,
Appellant, however, urges that other Pennsylvania appellate court decisions conflict with the
Whitcomb
rule and require that a jury be instructed that, even in the absence of evidence as to the normal commercial rate of interest during the period of detention, the jury can find
any
rate of interest not exceeding 6%. After an examination of the decisions upon which appellant relies we are in accord with Judge Morrison’s observation in
Shevalier v. Postal Telegraph Co.,
An examination of the Whitcomb case clearly indicates that the principle therein enunciated is that, in the absence of any evidence of the normal commercial rate of interest during the period of detention, a presumption arises that such rate is the legal interest rate of 6%. Whether this principle requires that the jury in such a situation arrive at the amount of detention money only on the basis of the legal rate of interest depends on the legal effect of a “presumption”. 8
In 9 Wigmore, Evidence §2491 (3rd ed.), it is said: “The peculiar effect of a presumption ‘of law’ (that is, the real presumption) is merely to invoke a rule of law compelling the jury to reach the conclusion
in the absence of evidence to the contrary
from the opponent. If the opponent
does
offer evidence to
*174
the contrary, (sufficient to justify the judge’s requirement of some evidence), the presumption disappears as a rule of law, and the case is in the jury’s hands free from any rule ... It is, therefore, a fallacy to attribute ... an artificial probative force to a presumption, increasing for the jury the weight of the facts, even when the opponent has come forward with some evidence to the contrary.” In accord with this view, we have recently stated in
Waters v. New Amsterdam Casualty Co.,
■Absent a presumption.and absent
any
evidence as to the commercial rate of interest.during the period of detention, in what manner can a jury arrive at the amount of detention money? As Mr. Justice' (now Chief Justice) Jones said in
Fidelity-Philadelphia Trust Co. v. Commonwealth,
*175 Unless we are to permit a jury to arrive at tlie amount of detention money by conjecture or speculation there must be some yardstick to guide them in their determination. The Whitcomb case delineates this yardstick. It decides that if there is no evidence as to the normal commercial rate of interest during the detention period, the law, by resorting to a presumption, will set up such a standard. If the legal rate of interest during the period of detention is not the normal commercial rate, all the condemnor is required to do is offer proof of what the normal' commercial rate of interest was during the period of detention. Upon the introduction of such proof, the presumption of the Whitcomb case disappears. If we are to adopt a rule that a jury may award detention money :on the basis of any rate of interest not exceeding 6% in the absence of any evidence whatsoever to guide the jury in arriving at the appropriate rate of interest then speculation and conjecture, rather than proof, form the basis of the jury’s award.
Under the instant circumstances we have no recourse other than to follow the principle of the Whit-comb case and approve the instruction of the court below that, in the absence of evidence to the contrary, there is a presumption that the normal commercial rate of interest during the detention period was the legal rate of interest and that the amount of detention money, if any, to be awarded should be on tlie basis of such legal rate of interest. A condemnor, without the expenditure of either considerable money or effort, can avoid the effect of this ruling simply by proving as to the condemnee that the legal rate was not the ordinary commercial rate of interest during the period of detention.
Judgments affirmed.
Notes
“Detention money” is used synonymously with compensation awarded by reason of delay in payment of damages by the condemnor to the condemnee or, stated otherwise, “the damage due to delay in payment over the period between the exercise of the right of eminent domain and the final adjustment of the damages inflicted by it”:
Gitlin v. Pennsylvania Turnpike Commission,
The parties agreed on the period of detention, not the rate of interest.
The opinion of the court below fully supports this interpretation of its charge.
For instance, the eondemnee’s demand may have been so exorbitant as to justify the condemnor in refusing to pay or the condemnee may have been otherwise at fault.
Ross v. Pennsylvania, R. R. Co.,
Justification for the allowance of detention money was aptly set forth by Mr. Justice Mitchell in
Richards v. Citizens Natural Gas Company,
As tbe trial judge indicated: “The language used by the lower court [in the Whitcomb ease] seems to be much more positive in telling the jury they can allow 6% interest than the language used by the trial judge in the instant case.” The lower court had charged: “Now, gentlemen, when you conclude what the value of the property was in July 1916, you will render a verdict for the plaintiff for that amount and add to it interest at the rate of 6% from July 27, 1916, down to the date of your verdict. The owner of the property was entitled to whatever you determine was the value of the property as of that date, and of course, not having received it, she is entitled to the earning power, which the law fixes at 6%, and to your verdict should be added that amount.”
