The Court said: I?The mere admission by an administrative tribunal ?of matter which, under the rules of evidence applicable to judicial proceedings, would be deemed incompetent (United States v. Abilene-&S.R. Co. 265 U'. S.'274, 233, 63 L. Sd. 1016, 1022, 44 Sup.Ct.Rep. 565), or mere error in reasoning upon evidence introduced, does not invalidate an order.

In deciding the case the Commission had relied in part upon evi­dence which it had received in another case involving the station of St. John on the same Railroad. One of the grounds for set­ting the order aside was the action taken by the Commission in relying upon the evidence in the other case. The Court said: ,7Can the commission take into consideration t he knowledge that it received at the hearing in the St. John Station Case as to the methods, practices, and incidents attendant to the shipping of live stock to and from St. John and apply it to this case because the two stations exist under essentially similar phy- - 25-
