delivered the opinion of the court.
It is stated in the complaint that appellant was a common ' carrier, and, although denied in the answer, it seems • to have been conceded at the trial that such was the capacity in which he contracted. The trial court assumed by its instructions that his liability was to be controlled by the law applicable to common carriers, and the correctness of such assumption is not challenged upon this appeal. In determining his liability, we shall therefore assume that he contracted as a common carrier, and measure his responsibility for the damage resulting from the freezing of the goods in transit by the strict rules governing such carriers, except so far as the same were modified by the special contract of the parties offered in evidence.
In reference to such special contract, the following is the substance of the testimony of H. N. Wood, one of the firm of Wood Bros., and it is not contradicted: “That in November, 1885, witness was a forwarding agent at St. Elmo; that as such forwarding agent he received from the Union Pacific Railroad Company at St. Elmo a lot of goods marked ‘ Nursery Stock, etc.,’ consigned to H. A. Parcells *52& Co., plaintiffs; that he delivered these goods to defendant, Carr, for transportation to Aspen; that he obtained these goods from the railway company on presenting the bill of lading under which they had been shipped from Denver to St. Elmo; this bill of lading had been given to witness by plaintiff Parcells; that, at Parcells’ request, witness went with him, to find a freighting outfit to transport the goods in question from St. Elmo to Aspen; that they found some freighters whose wagons Parcells examined and pronounced to be not large enough for properly packing the nursery stock so as to protect it from frost, and so not suitable; that, on Parcells’ request, witness introduced him to defendant, who was about to engage in freighting between St. Elmo and Aspen; that, on the afternoon of the same day (November 1st), defendant’s wagons arived at St. Elmo from Arizona, and that Parcells examined these wagons and pronounced them .to be ‘ just the thing he wanted; ’ that these wagons were the ones in which the goods were packed for shipment; that the wagons examined in the morning by witness and Parcells were such as were ordinarily used' at that time for freighting between St. Elmo and Aspen; that in the several conversations witness had with Parcells witness told Parcells that he would be obliged to ship the goods at owner’s risk, and defendant also stated that he wanted to receive the goods at owner’s risk; that it was. agreed that the goods should not remain over-night on top of either range; that witness afterwards, in presence of Parcells and defendant, made a memorandum of the arrangement between Parcells and defendant; this memorandum was to go on the bill of lading, and from it witness afterwards drew up a bill of lading as the contract between Parcells and the defendant.” The witness further testifies that he took the goods out of the railway car and superintended their packing in the defendant’s wagons; that they were packed with hay on the bottom and sides, and hay and'grain on top; that they were packed in this way to keep them from freezing, the matter of their freezing hav*53ing been discussed; that witness had been in freighting business more or less since 1818; that the letters “ O. B.,’’ in connection with the word “ freezing,” signify “ owner’s risk.”
The bill of lading introduced in evidence reads as follows :
“No.-. St. Elmo, November 2d, 1885.
“ Way-bill of goods forwarded by Woods Bros., by James Carr, freighter to Aspen, Colorado.
“ If this consignment is delivered in Aspen by the evening of November 4, 1885, the freighter shall be paid $10 extra above the regular freight. It is further agreed that the said freighter shall not expose his load on either range over night, and take the best possible care of same.
“ Beceived the above goods in good order and .condition, which I agree to deliver to consignee in same order and condition.
“ [Freighter’s signature.]
“ James Carr, per Mo.”
This was duly signed for Carr, and accepted by the forwarders for appellees. It constitutes the only written evidence of the contract between the parties, and must be taken as the only contract for the transportation of the *54goods. Evidence of the previous conversation and negotiations of the parties leading up to the contract cannot be considered for the purpose of altering its terms.
The measure of the liability of appellant must be determined by the written contract. By the terms of this instrument he expressly acknowledges the receipt of the property in good order, and expressly agrees to deliver it in the same condition. This is the customary contract of a common carrier. There is no agreement to deliver the property in Aspen by November 5th, although it does contain a stipulation by the consignee to pay $10 additional if the property should be delivered in Aspen by the evening of November 4th. It is also agreed that the property shall not be exposed on either range over night, and that the freighter will take the best possible care of the same. It is further provided that the property shall he carried at the owner’s risk of freezing. It is, in fact, the ordinary common carrier’s contract, loss by freezing excepted, and an agreement that the property should not be exposed to the severity of the ^weather which might prevail at the summit of the mountains to he crossed. But there was no agreement that the property should be delivered at its destination by the 5th day of November, as alleged in the complaint; and the submission to the jury of the question whether there was such an agreement was error. As we have seen, the liability of appellant was fixed by the written contract, and by that alone.
The evidence shows that this was appellant’s first experience in freighting over the road between St. Elmo and Aspen; that his teams had just arrived in that section of the state, as Parcells well knew, and that Parcells examined the wagons before contracting with him, rejecting some and ..selecting others as suitable for the work. Under the cir.cumstances, he alone was responsible for the character of the wagons employed, and is estopped from claiming that .they were not suited to the business. And the testimony introduced by appellee tending to show that the convey*55anees selected were unsuitable was incompetent for the purpose of showing negligence on the part of appellant, and the instructions to the jury to this effect were erroneous.
The ruling of the trial court does not, as supposed by counsel, find support in anything which was said in the case of Transportation Co. v. Cornforth, 3 Colo. 280. The facts in the two cases are totally dissimilar. The selection of the car in which the goods were transported in that case was left entirely with the carrier. It was shown that it was customary to use refrigerator cars for the transportation of fruits in the winter season from New York, the place of shipment, to Denver, the place of destination, while the carrier in that instance used an ordinary box-car, with apertures through which the cold and snow entered. The evidence showed that the injury resulted from the gross negligence of the carrier; and the court held that public policy would not permit the carrier by special agreement to be relieved from damages occasioned by negligence or misfeasance in him or his servants. In that case the cars were selected by the carrier; in the case at bar the wagons were selected by the shipper and pronounced by him “ just the thing.” In addition to this, it would be unreasonable to measure the duty of an ordinary freighter in providing vehicles for the transportation of perishable goods with that of a company contracting for transportation across the continent by rail.
As we have seen, the goods were shipped at the owner’s risk of freezing. This does not, however, relieve the carrier from loss resulting from his own negligence. The law will not permit a common carrier to contract against liability for his own negligence or that of his servants and employees. Transportation Co. v. Cornforth, supra; School Dist. etc. v. Railroad Co. 102 Mass. 552; Railway Co. v. Wilcox, 84 Ill. 239; Railroad Co. v. McCloskey, 23 Pa. St. 526.
Whether or not the loss complained of yas occasioned by *56the negligence of the carrier in this case, or resulted as an inevitable consequence from the condition of the road and the severe weather encountered, without the fault of the carrier, are questions for the jury to determine under proper pleadings and instructions. For the errors pointed out the case must be reversed and the cause remanded for further proceedings.
Reversed.
