delivered the opinion of the court.
The whole controversy turns upon the agreement as to the elimination of the average clause. It is important here for this reason: Plaintiff was partly insured in other companies not having this average clause, but containing a stipulation that in case he should take out other insurance by policies containing an average clause the first insurers should be entitled to share the benefits of such averages. Without going into the details of the various negotiations in regard to the policy issued as of July 30, 1914, and covered by the letter dated July 30,1914, heretofore quoted, we are of the opinion that the contract between the parties was for a blanket policy eliminating the average clause not only as to that policy, but from the rider in the February policy. Otherwise the letter quoted can have no meaning.
1. The existence of an average clause in a blanket policy would involve a contradiction of terms. A blanket policy is defined by the Supreme Court of Connecticut as follows:
“The characteristic features of a blanket policy are well understood. Its very essence is that it covers to *400its full amount every item of property described in it. If tbe loss upon one portion or item of tbe property exhausts the full amount of the policy, the whole insurance must be paid; there can be no apportionment of it. In the absence of a prorating clause, one blanket insurer among many insurers, whether blanket or specific, may be sued, and he must pay the whole loss if it is not in excess of his policy. His payment will give Mm certain equitable rights of contribution as against his coinsurers, but his legal obligation to pay the assured cannot be questioned. The contract holds him to that. These principles are elementary: 3 Joyce, Insurance, § 2492; 1 May, Insurance (3 ed.),§13; Ostrander, Fire Ins., § 204”; Schmaelzle v. London etc. Ins. Co., 75 Conn. 397 (57 Atl. 863, 96 Am. St. Rep. 233, 60 L. R. A. 536).
See, also, Scottish Union & National Ins. Co. v. Moore Mill & Gin Co., 43 Okl. 370 (143 Pac. 12); and generally Words and Phrases, title “Blanket Policy.” The evidence of Mr. Buehner and of Mr. Jelliff agrees this far: That Jelliff was soliciting the last policy of insurance; that Mr. Buehner was dissatisfied with the form of defendant’s policy theretofore issued; and that Jelliff prepared a form of rider eliminating the average clause, which would in effect have made the policies blanket policies, and gave several copies of it to Buehner. Jelliff says that the form was merely tentative and was not accepted by Buehner, but held up until he could consult Mr. Epperson of the Lumbermen’s Underwriting Alliance, at Kansas City, in regard to it, which institution also held policies upon substantially the same property. Buehner testifies that the contract was to go into effect at once and that Jelliff came to his office and got the form hi had himself prepared and which they had agreed upon for the purpose, as Buehner supposed, of preparing riders for the policy to be is*401sued and for the one already in force. We are of the opinion that Buehner’s version of the transaction is the correct one, and that the letter of July 30, 1914, while vague in some particulars, can he explained on no other theory. The words,4 ‘ Confirming my conversation with you this afternoon, this is to advise yon that we are protecting $5,000 additional on your blanket form covering new improvements,” etc., are significant. There was no other blanket form except the one under consideration, the one that Jelliff had prepared and retaken from Buehner’s office, and it is hardly probable that the letter would have been written referring to this form and informing Buehner that the insurance would be under it' if he had not already agreed with Buehner in regard to it. The further words, “Please accept this letter as sufficient evidence that yon are fully protected,” would have been false upon their face if it were the intent of the writer to notify Buehner that the policy to be issued would contain the average clause, the objection to which was that it would not fully protect him. The additional words, “We understand that this insurance attaches according to the wording attached to our policy No. 94713 for $5,000, dated February 3d,” are somewhat ambiguous; but the meaning of the preceding language is clear, and it is probable that the clause last quoted did not clearly express the writer’s meaning. The subsequent words, “We understand the forms are being adjusted, and I shall see yon Saturday and talk the situation over with you fully,” would indicate that the preceding words quoted, “According to the. wording attached to our policy No. 94713,” were intended to apply prospectively to that policy as it would appear when the new form agreed upon had *402been prepared. Else why speak of adjusting forms if only one form remained to be prepared or adjusted?
It is urged that a letter written by Mr. Buehner to Mr. Epperson supports Jelliff’s claim that the blanket form prepared by him had not been accepted by plaintiff. The substance of the letter is as follows:
“Inclosed please find a form that we have taken up with the local office here in regard to the plant account and the lumber in and about the mill, which takes the mill rate. As you no doubt know, the Carlton Lumber Company leased the mill of the Carlton Consolidated Lumber Company with the understanding that all new machinery and all additions to the plant must be put in by the Carlton Lumber Company, and that we must carry our own insurance covering this improvement. We have a book in which we have all the items enumerated, which covers the cost of the plant that the Carlton Lumber Company has put in, in order to enable us accurately to ascertain at any time, in case of fire, the cost of the work that the Carlton Lumber Company has put in and all records up to date. I would ask you whether you think it would be advisable to make a copy of this list, which would mean five or six pages, and attach it to the policies, as we do not care to have any dispute in case of fire. We intend to place the insurance on the lumber in the dry shed, planer shed, dry kilns, and all the lumber in and about the mill, in one policy with one company, and we would like to do the same with our plant account, putting it, say, with one or two companies, having all the forms exactly the same. Our plant account, including the stable plant, is about $35,000, with some deductions on account of foundations and support.”
The only suggestion asked in this letter is as to whether it would be advisable to attach a list of new machinery and additions to the plant to their policies. There is not one word in it asking for any suggestion as to the form of rider inclosed, and the letter is more *403a notification to these people of the form of rider the insurer proposed to adopt respecting all insurance than a request for advice, except as to a matter not connected with the form. The answer indicates that Mr. Epperson so understood it. He makes no suggestion as to the form of rider, hut does make a suggestion as to the matter of attaching lists of the property to the policies, and intimates a desire to participate in future insurance.
2. Much as we should desire for the satisfaction of counsel to discuss in detail the evidence, both oral and written, upon which we base our conclusions, it is impossible to do so and compress our opinion into any reasonable space. The discussion of it in the appellant’s brief consumes what would be the equivalent of 40 or 50 pages of the Oregon Eeports, and yet it is not unnecessarily long. It would be of no general interest, and the law in regard to the reformation of insurance policies is so well settled that there is practically no dispute between counsel in regard to-it. We are fully satisfied that it was the contract and intent of the parties that, in consideration of the insurance covered by the July 30th policy being given by the plaintiff to the defendant company, a rider in the form set forth in plaintiff’s complaint should be attached to it, and that a like rider should be substituted on the February policy and that by mistake this was omitted.
3. That the plaintiff was somewhat careless in not examining the policies issued more carefully is, perhaps, true; but this negligence should not prevent relief. There are few, if any, cases where the aid of equity is asked to reform mistakes in written instruments in which there is not disclosed some degree of negligence by the injured party, and this is particularly true as to insurance policies. The average per*404son insured describes Ms property to the agent, pays his premium, receives his insurance policy, and goes on Ms way rejoicing, usually not reading it, and not understanding half of it if he does read it. It is in evidence here that plaintiff’s president did not understand the difference between a blanket policy and one containing the average clause until rival insurance agents enlightened him, and that this information was the cause of his determination to have all his policies blanketed. It is to the credit of insurance companies that as a rule they usually keep their promises and give the insured the Mnd of policy they agree to give him, and this fact has led the insuring public to accept policies issued by reliable companies without thorough examination. To hold that plaintiff cannot recover because its officers did what nearly everybody else does, namely, accepted the policies sent them without an industrious, technical examination of their contents, would be unjust.
Believing that the findings of the court below are fully sustained by the testimony, the decree will be affirmed. Affirmed. Modified on Behearing.
