The plaintiff and defendant are each corporations engaged in construction work. The defendant had a contract with the Illinois Central Railroad to do a certain construction work in Kentucky. It thereafter entered into a sub-contract with the plaintiff corporation, employing it to do a portion of the work, described in the contract, for the prices therein named: to-wit, ‘ ‘ earth excavating, 19y2 cents per cubic yard; clearing, $25 per acre; grubbing, $8 per station.” This contract between the parties to this suit was in the form of a letter addressed by plaintiff to defendant upon May 30, 1902, and an acceptance endorsed thereon by defendant. It contained a provision, to-wit, “All in accordance with the specifications *46and to the satisfaction of the chief engineer of construction of the Illinois Central Railroad Company.” After some delay in obtaining “access and right .of way” to and over the grounds where the work was to be done, plaintiff engaged in the performance of the work. During the progress of the work of excavating, the plaintiff reached a substance termed ‘ ‘ cemented gravel,” more difficult and expensive in excavation than earth. Plaintiff called defendant’s attention to the quality of this substance, and proposed to stop work until an agreement was reached as to payment for excavating the same.
The evidence tends to show that there was an agreement reached, that plaintiff should go forward with the work and should be allowed the reasonable value of excavating the “cemented gravel.” With this .understanding the work was performed, and plaintiff received payment therefor according to the terms of the contract between the parties, except as to the work done of excavating the ‘ ‘ cemented gravel, ’ ’ which was paid for at the price of excavating earth. Plaintiff demanded in addition a further sum equal to the reasonable value of performing that work. Plaintiff further demanded that it should be allowed the cost and expense of “assembling teams and wagons” for the doing of the work in question and being compelled to hold them in readiness during the delay occasioned by the defendant’s failure to procure for. plaintiff “access and right of way” to the property within a reasonable time after defendant had required plaintiff to be ready with “men and teams” and other appliances for doing the work.
Upon the failure of the defendant to comply with these demands, the present suit was brought in a petition containing five counts. Three of the counts were dismissed or nonsuits taken therein on the trial. Copy of the petition and summons was personally served upon the defendant to the April term, 1904, of *47the circuit court of the city of St. Louis. The defendant made default, and judgment was rendered accordingly on the first and third counts of the petition. The first count of the petition alleged, in substance, that defendant on or about the 30th of May, 1902, employed plaintiff to do the excavating in and about Capp’s Cut, on the Illinois Railroad; that plaintiff, excavated 9166 cubic yards of a material known as “cemented gravel,” the reasonable value of which was seventy-five cents per cubic yard, and prayed judgment accordingly. The third count alleged cause of action against defendant for failure to procure the right of way and access to the grounds on which said work was to be done at the time indicated by defendant, whereby plaintiff was put to the cost and expense of $2261. The items, dates and particulars of all of which were incorporated in said third count, as follows:

“Wherefore plaintiff prays judgment for said sum of $2261 and interest thereon.”
The court appointed a referee “to examine into and assess the damages in this case.” After taking proof, the referee reported, recommending judgment *48in favor of plaintiff on the first count for $5087.13, and on the third count for $1156 — total $6243.13 with interest from March 19, 1904. In reaching his conclusions on the second count, the referee excluded from view the cost and expense “for delaying the graders and traction engine, amounting to the sum of $1005,” hut allowed all the remaining items of the account set forth in the third count of plaintiff’s petition.
On hearing of the evidence before the referee, it was not shown that any copy of the specifications of the contract between defendant and the railroad was exhibited to plaintiff at the time of the contract made between plaintiff and defendant, or at any othér time “before plaintiff encountered the ‘cemented gravel’ and refused to do further work unless it was to be paid therefor.” There was evidence tending to show the defendant agreed to pay plaintiff a reasonable value for doing the work of excavating the “cemented gravel.”
Exceptions to the referee’s report were filed by both parties and overruled. Motions for new trial filed by both parties were also overruled, and both perfected their appeals to this court — the plaintiff from so much of the finding of the referee as excluded any allowance for the delay of the graders and traction engine; and the defendant from the judgment against it on the first count.
I. The two appeals taken in this case present for review the question of the correctness of the affirmance of the referee’s report on the first and third counts of plaintiff’s petition.
Taking these in order. The default made by the defendant, after personal service, in this action was an admission on its part ©f every traversable allegation contained in the first count of plaintiff’s petition, and precluded the defendant from controverting thereafter any sufficiently stated cause of action contained *49in said connt. [Barclay v. Picker, 38 Mo. 143; Lombard v. Clark, 33 Mo. l. c. 309; Price v. Page, 24 Mo. l. c. 67.]
In considering this count of the petition, the referee should have confined the testimony of the defaulting defendant to evidence tending only to mitigate or diminish the damages, and should have excluded all testimony or evidence tending in any manner to controvert the cause of action stated in this count of the petition, for that was admitted and confessed by the default of the defendant. It was sufficient to entitle the plaintiff to a recovery, that the allegations in this count set forth a good cause of action or a legal right to a recovery. In applying this rule to the conduct of the case before him, the referee should not have required plaintiff to offer evidence that it had a contract with defendant whereunder it was entitled to the reasonable value of excavating “cemented gravel, ’ ’ for the existence of such contract was expressly alleged as the ground of plaintiff’s right to recover on the first count of the petition, and was conclusively established against defendant after the default. The referee should have admitted only testimony tending to show what was the reasonable value and the amount of “cemented gravel” excavated by plaintiff; and should have rejected the evidence offered by defendant tending to controvert plaintiff’s right to recover by showing that plaintiff did not have a contract with defendant' for payment for the work of excavating “cemented gravel.”
By the wide range of testimony admitted by the referee, defendant sought to prove that plaintiff was debarred from a recovery under the first count of its petition, because said count declared upon a written contract, under the terms of which contract plaintiff had bound itself to accept a classification of “cemented gravel” as earth, and, hence, was only entitled to be *50paid for excavating “cemented gravel” at the price fixed for excavating earth.
In the first place, if the facts warranted such defónse, it was indispensable that they should have been .affirmatively pleaded by defendant. It could not be set up after a default. In the second place, it is nowhere shown in the evidence that any such classification was made and shown to the plaintiff at the time of the written contract of May 30, 1902, nor after-wards. Again, the contract of May 30, 1902, does not, either by terms or legal, intendment, provide for any classification of the specific substance or work.mentioned in said contract: to-wit, “Earth excavation, clearing, and grubbing.” It simply provides that these things should be done “in accordance with the specifications and to the satisfaction of the chief engineer of the Illinois Central Railroad;” and there is no proof in the record that any specifications of “cemented gravel” as earth by said.chief engineer were ever submitted to plaintiff at any time. Hence, this point is ruled against defendant.
II. Defendant also contends that the proof introduced before the referee afforded the basis for the application of the doctrine of waiver and estoppel as against any recovery by the plaintiff on this count of its petition. The answer to this is, that estoppel, unless it is shown or made to appear in plaintiff’s case, is always a matter of affirmative defense and must- be pleaded in order to be available; and that the same rule applies as to waiver in all cases except in actions on contracts of insurance. [McCullough v. Phoenix Ins. Co., 113 Mo. l. c. 616.]
III. Appellant (defendant) further contends that the first count of plaintiff’s petition was based upon the written contract of May 30, 1902, wherefore it was error to permit plaintiff to recover on the subsequent oral contract, dated in August, 1902. This conten*51tion is based upon a misconception of the cause of action stated in this count. The cause of action stated in this count is a quantum meruit for the reasonable value of work and labor performed in excavating the “cemented gravel.” The reference to the date of May 30, 1902, as being on or about the date of the agreement sued on, was neither a substantive allegation nor was it intended to make the contract of that date, afterwards introduced in evidence, the basis of the suit. This is necessarily so, for there is no allegation in the petition asking for a recovery for either of the three things exclusively mentioned in the contract. On the contrary, the cause of action is based upon an alleged agreement for excavating a material or substance wholly different and distinct from those mentioned in said written contract. It is impossible, therefore, for the count to have been one for the violation of the written contract. The allegations of said count could have been sufficiently stated without referring to the contract of May 30, 1902, in any way, but such reference was at most surplusage; and the fact that the allegation did not refer to anything covered by the contract in question, clearly shows that it could not be based thereon. This count did contain the- elements of a good cause of action for the violation of an oral contract to .-pay the reasonable value of excavating “cemented gravel,” as follows: “That plaintiff excavated 9166 cubic yards of material, known as “cemented gravel,” the reasonable value of which was seventy-five cents per cubic yard, amounting to $6874.50, no part of which has been paid and judgment is asked therefor.” The fact that it also contained other references not made the basis of the demand for judgment, does not destroy its legal sufficiency. It is the settled law of pleading, that the defective statement of a cause of action is a radically different thing from the statement of a defective cause of action. The former is cured by a verdict or a default; the lat*52ter is incurable at any stage of tbe canse and may be taken advantage of for tbe first time on appeal to a court of last resort. This count of tbe petition sufficiently alleges tbe oral agreement, and tbe breach thereof, upon which tbe finding was made by tbe referee. It is impervious to attack, after default by defendant, for want of definiteness, surplusage, or any other defect in statement, except tbe failure to state any cause of action.
We, therefore, bold that tbe finding of the¡ referee on tbe first count of tbe petition was properly affirmed by tbe trial court.
IV. Tbe only theory on which tbe learned referee excluded any allowance to plaintiff for tbe delay of its graders and traction engine was tbe assumption by him that tbe inclusion of a charge for tbe specific loss thus suffered in tbe itemized account, which itemized account was set forth in tbe third count of tbe petition, was not sufficient to make, those items a part of tbe cause of action alleged in said third count of tbe petition.
We cannot concur in that view. Tbe code of civil procedure provides: “And in actions instituted upon an open account or an account stated where tbe items are set forth in or annexed to tbe petition, if tbe defendant has been personally served by tbe delivery to him of a copy of said account. . . .if tbe defendant makes default, be shall be considered as admitting tbe account to be due as set forth in or annexed to tbe petition, and final judgment may be rendered against him for tbe amount thereof at tbe time of entering tbe default.” [R. S. 1909, sec. 1799.] -
Tbe only prerequisite to a final judgment in a case coming within tbe terms of tbis statute is, that tbe defendant shall have been served personally with a copy of tbe petition and of tbe included or appended itemized account. That was done in tbis case, and tbe *53court, without any reference, might have made a finding for the aggregate items contained in this count of the petition when defendant made default. [Clark v. Evans, 64 Mo. 258.]
This statute is predicated upon the idea that an itemized account inserted bodily in a petition or annexed thereto, is just as much a part of the petition as any allegations preceding or following the account. It expressly provides for the rendition of a final judgment after a default as in this case.
We, therefore, hold that the referee and the circuit judge erred in not making a finding of the amount of the items of expense incurred by plaintiff for the delay of its graders and traction engine, since these were contained in the itemized account embodied in the petition. The finding herein as. to the first count of the petition is affirmed, and the finding as to the second count of the petition is reversed, and the cause remanded with directions to the trial court to make a finding on the second count of the petition in favor of plaintiff and against defendant for the aggregate of the itemized account set forth therein, and to render judgment in plaintiff’s favor for the amount of the findings on both the first and third counts of the petition.
Boy, C., concurs.PER CURIAM. — The motion for rehearing is overruled. The opinion, however, will be modified in. the following particular:
Upon reconsideration, we are satisfied that the ruling of the referee disallowing any recovery on the third count for the delay on account of the graders and engines was correct. We are of the opinion that the items set out in the petition, being for unliquidated damages, do not constitute an open account within the. meaning of section 1799, Revised Statutes 1909, and consequently this itemized statement does not enlarge *54the scope of the allegations in the petition. It is ' therefore ordered that the judgment of the circuit court be affirmed.
