reasonable intendment will be made in its support. Roberts v. Consumers’ Can Co., 102 Md. 362, 369, 62 A. 585, 111 Am. St. Rep. 377; Dominion Marble Co. v. Morrow, 130 Md. 255, 260, 100 A. 292; McDonald v. Real Estate Board of Baltimore City, 155 Md. 377, 382, 142 A. 261; Pumphrey v. Pumphrey, 172 Md. 323, 191 A. 235; Boston Water Power Co. v. Gray, 6 Metc., Mass., 131, 165; Leslie v. Leslie, 50 N. J. Eq. 103, 24 A. 319. In this case the problem of determining the market prices of millfeeds over a period of 7 years and 7 months was not a simple one. The arbitrators found that the prices of millfeeds in Baltimore, which is not a primary market for such byproducts, are affected by the quotations of the primary markets as well as by local conditions and imports from South America. They also found that the quotations in the primary markets varied from 25 cents to $1 per ton. After considering various suggestions for determining the market prices in Baltimore, the arbitrators decided to take each weekly quotation per ton for Buffalo, which is a primary market for millfeeds, add the freight to Baltimore, and then deduct 50 cents. While this criterion may not have been exact, the arbitrators did not exceed their power in adopting it.
When, however, we come to the decision of the arbitrators to reject the claim for underpayments in the period from August 31, 1937, to July 31, 1942, we have an entirely different situation. In order that an award shall be binding, the arbitrators must follow exactly the authority given them by the agreement of the parties. If they exceed their authority, the award is void to that extent. In a case in New York Chief Judge Cardozo said of arbitration: “The question is one of intention, to be ascertained by the same tests that are applied to contracts generally. No one is under a duty to resort to these conventional tribunals, however helpful their processes, except to the extent that he has signified his willingness. Our own favor or disfavor of the cause of arbitration is not to count as a factor in the appraisal of the thought of others.” Marchant v. Mead-Morrison Mfg. Co.,* 252
