delivered the opinion of the court.
This is a writ of error to review the record of a judgment entered upon the finding of the court. On February 23, 1912, plaintiff below, defendant in error, filed suit in assumpsit against plaintiff in error and six other common carriers, alleging that on or about March 28, 1907, the.carriers were engaged in interstate commerce, and that on that date the defendant, Cincinnati, Hamilton & Dayton Railway Company, for the usual and legal rate of compensation,' agreed to transport from Piqua in the State of Ohio, to San Francisco, in the State. of California, safely and within a reasonable time, certain goods described in the bill of lading issued by the said defendant, which said bill of lading or contract was in writing and set up in the declaration in hcec verba.
This declaration further alleged that the other common carriers, defendants with lines of railroad, extending between the points named “adopted and ratified said contract as their own, and as their contract with the plaintiff.” It also alleged the default of all the defendants in their promise to safely carry within a reasonable tim'e, and to deliver the goods, etc. To this declaration plaintiff added the common counts, and the defendant, plaintiff in error here, filed the general issue. Later, by stipulation of the parties, the suit was dismissed as to all the defendants except plaintiff in error.
On January 24, 1913, the plaintiff filed an amended declaration which alleged that on the said 28th day of March, 1907, one Judson Harmon was the receiver of the Cincinnati, Hamilton & Dayton Railway Company, engaged in interstate commerce, etc.; that he paade, executed and delivered the bill of lading or *555contract in writing, which is, as in the original declaration, set up in h(BG verba; that he failed to keep the contract to safely carry and deliver; that on the 19th day of August, 1909, the receiver was duly discharged and defendant then resumed possession of the property and promised to and assumed and agreed to pay all the debts and liabilities created by the receiver; that by reason thereof “by force of the statute in such case made and provided, the said defendant railway company became liable to pay to the said plaintiff the said sum of money, value of the property aforesaid, together with a reasonable attorney’s fee to be fixed by the court in case of recovery.” The common counts were also attached.
To this amended declaration the defendant filed a plea of the general issue and later, by leave of court, certain special pleas, one of which set up that the cause of action as stated in the amended declaration was barred by the statute of limitations. To this plea the plaintiff filed a general demurrer, which was overruled, and thereafter a replication thereto filed by plaintiff. April 18, 1918, the'defendant, by leave of court, filed an amended first additional plea, in which it set up that the supposed causes of action in the amended declaration alleged were other and different causes of action than those alleged in the original declaration filed February 25, 1912, and that they had not accrued to the plaintiff at any time within 5 years' next before the commencement of suit thereon by the filing of the amended declaration. To this amended first additional plea the plaintiff demurred. The demurrer was sustained and defendant, electing to stand by his plea, the cause was submitted to the court, which found the issues for the plaintiff and his damages at $2,105.30, for which sum judgment was entered, defendant’s motion at the close of all the evidence for a finding in its favor being overruled.
The error here assigned and argued is the action *556of the court in sustaining plaintiff’s demurrer to defendant’s amended first additional plea to the plaintiff’s amended declaration. The declaration, as amended, contained the common counts, and the plea filed April 18, 1918, purported to answer the entire declaration. This ,plea failed to show a defense to the common counts and was, therefore, properly held bad on demurrer. Goodrich v. Reynolds, Wilder & Co., 31 Ill. 490; People v. McCormack, 68 Ill. 226; Gebbie v. Mooney, 121 Ill. 255. - However, aside from this technical point, on which the judgment of the lower court must be affirmed, we think the merits of the case are with defendant in error. It is apparent that if the cause of action-set forth in the amended declaration is upon a “written contract” within the meaning of section 16 of the Limitation Act (Hurd’s Eev. St. 1917, p. 1889, J. & A. ft 7211), which provides for á 10-year limitation for actions therein described, then the demurrer to the additional plea which set up a 5-year limitation, applicable to actions on “unwritten contracts, express or implied,” as provided by section 15, was properly sustained.
We understand plaintiff in error to contend that the cause of action as stated in the amended declaration is-based on an “unwritten contract, express or implied”; that the liability of the defendant as therein stated arises out of a contract implied from the “Carmack Amendment” to the Interstate Commerce Act, which makes the initial carrier responsible for the delivery of a shipment at its destination, whether that destination is or is not on its line.
It is pointed out that the original declaration set up a specific contract by which defendant agreed “to carry to its usnal place of delivery at said destination, if on its road, otherwise to deliver to another on the route to said destination,” and alleging that the other carriers then named as defendants adopted and ratified this contract. On the other hand, the amended *557declaration alleges the defendant became liable “by force of the statute in such case made and provided.” Plaintiff in error therefore argues it is apparent the cause of action is other and different from that first stated, and is based on an unwritten contract, express or implied, arising out of the “Carmack Amendment” to which the 5-year limitation provided by section 15 is applicable.
While the contention is plausible we think it ignores the fundamental rule obtaining in the interpretation of contracts to the effect-that: “All laws in existence when an agreement is made necessarily enter into and form a part of it as fully as if they were expressly referred to or incorporated into its terms.” Armour Packing Co. v. United States, 153 Fed. 1, p. 19. This rule is, we think, peculiarly applicable to contracts between carriers and shippers in interstate commerce. If we thus incorporate the express provisions of the “Carmack Amendment,” section 20 of the Act to regulate commerce, into the bill of lading, which here constitutes the written contract between the parties and which is set up in hcec verba in both the original and amended declarations, we think it must be interpreted as a written contract by defendant in error to carry to final destination over its own line, if possible, and, if not, then partly over the lines of its agents and subsequent carriers. Northern Pac. Ry. Co. v. Wall, 241 U. S. 87; Illinois Cent. R. Co. v. Johnson, 34 Ill. 389; Coats v. Chicago, R. I. & P. Ry. Co., 134 Ill. App. 217; Shafton Co. v. St. Louis, I. M. & S. Ry. Co., 174 Ill. App. 121; L. Starks Co. v. Michigan Cent. R. Co., 207 Ill. App. 333.
The contract here is not created by an implication derived from the statute. The statute enters into the interpretation of the contract, created in writing by -the voluntary acts of the parties to it. The allegation of the declaration as amended that the defendant became liable “by force.of the statute” is, therefore, sur*558plusage. The precise point is not decided by. any authorities cited. There is language in Illinois Cent. R. Co. v. Miller, 32 Ill. App. 259, which would seem to sustain the contention of plaintiff in error, but it was unnecessary to the decision of the case, and must be regarded as mere dicta. That case relies on Plumb v. Campbell, 129 Ill. 101, where the court said:
“If it be true that the agreement, as set forth in writing, is so indefinite as to necessitate resort to parol testimony °to make it complete, the law is, that in applying the statute of limitations, it must be treated as an oral contract. Both reason and authority support this view.”
If we apply this rule here it is apparent, we think, that the bill of lading, as interpreted in view of the ‘ ‘ Carmack Amendment, ’ ’ would not necessitate oral evidence to establish its terms. On principle, we can see no more reason why the interpretation of this bill of lading in the light of the “Carmack Amendment” should convert the written contract into an oral one, than the interpretation of a promissory note or other writings, in the light of the statutes existing at the time of their execution, with reference to the payment of interest thereon, would convert such written contracts into oral ones. Matthias v. Cook, 31 Ill. 83; Heissler v. Stose, 131 Ill. 393; Dick Co. v. Sherwood Letter File Co., 157 Ill. 325.
The judgment will be affirmed.
Affirmed.
