Mr. Justice Holmes

delivered the opinion of the court.

On December 13, 1916, the' steamer Bay Port, while passing through the Cape Cod Canal, ran ashore on the south bank and the next day sank diagonally across it. In January; 1917, the Canal Company filed a libel against' the White Oak Transportation Company, the owner of the steamer, to recover for damages suffered by the canal and the obstruction of traffic through it. It also filed a libel against the T. A. Scott Company, Inc., a wrecking company, for negligence in dealing with the steamer after it had grounded; but this company has been exonerated and is not before us. In May, 1917, the Transportation Company filed a libel against the Canal Company, to charge it with a total loss of the steamer and freight, and in March, 1918, the Northern Coal Company intervened seeking to hold the Canal Company for a total- loss of the cargo, which was coal.- The causes were heard together below and were consolidated by'agreement for -hearing and determination upon'one record here.- The District Court found no negligence on either side and dismissed all the *343 libels. 251 Fed. 356. The Circuit Court of Appeals held the Transportation Compány liable to the Canal Company, and reversed the decree in that cause. 265 Fed. 538. It' also dismissed the; intervening petition of the .owner of the coal. 267 Fed. 176.

We agree with the Circuit- Court of Appeals' that- the owners of the Bay Port and the Canal Company both ought, to have known that it was unsafe to take the vessel’ through the canal. We agree with the. dissenting Judge in the Circuit Court of Appeals that the loss of .the cargo must be attributed to the joint negligence of the two; and we are of opinion that the amount of that loss, that suffered by the vessel and that suffered by the canal should be added together and divided between the Bay Port and the Canal.

The Bay Port was a lake built steamer of the whaleback type, 265 feet long and of 38 feet beam, which had been brought to the Atlantic. When deeply laden she steered somewhat awkwardly but as well as other vessels of the type. She was loaded with 2393 tons of coal and had a draft of eighteen feet two inches aft and seventeen feet eight inches forward, when soon after noon on December 13, 1916, she appeared at the western or Wing’s Néck entrance to the canal. Her captain was a man of experience and had gone through the canal twice with the Bay Port when empty, never when loaded. He had been solicited by the Canal Company to go by way of the canal, the Company representing the canal to be twenty-five feet deep throughout as- its charter required. Mass. Act of 1899, c. 448, § 3.

Havirig got permission the Bay Port started in tow of a tug with a competent pilot. The tide was about half out, running west at about three knot's an hour. After proceeding halfway' through the canal the vessel passed over a shoal where there was not more than twenty-one or *344 twenty-two feet of water, and soon after sheered toward the north bank, and then toward the south bank where she grounded, at about a thousand feet from the shoal. It is strongly argued that this and the shoal next to be mentioned caused the trouble, but, notwithstanding The Pennsylvania, 19 Wall. 125, we will accept the finding of the two Courts that they were not.the proximate cause. Two'tugs'and the superintendent of the canal came to the help of the Bay Port but could not get her off as the tide was falling. The tugs kept her upon the bank and the next morning a hole was discovered in her bottom,, but was plugged. Arrangements had been made to.lighten the cargo when unexpectedly, about 10.15 a. m., she slid into the channel. The pilot with whom she started had left but another canal pilot who seems to have taken his place ran upon the bridge and directed the captain to start his engines at full speed to prevent her drifting upon the .opposite bank'. She was down at the head from 18 to 30 inches with a list to port of from 15 to 24 inches. Since 6 a. m. the tide had been running to the.east, the direction in which the steamer was going, and the pilot ordered a tug to take her in tow and started toward the east. The Bay Port proceeded about a mile; but after she had passed another shoal spot by some two thousand feet', ■sheered again two or three times and stranded on the north bank, the bow came clear and swung down stream and then she sank and became a total loss. ■

The Circuit Court of Appeals thought that the master was responsible for the loss because he did not displace the pilot and prevent the vessel proceeding before she was fully pumped put, the cargó adjusted and slack water had come, which he might have done, by holding her in ..the channel by the. tugs that were present or by tying up to some dolphins that he passed-.- Upon this, point we agree with the' Reasoning of the District Court. The emergency y^as serious. The canal regulations provided. *345 that -in the event of grounding the canal authorities should "have the right to direct all operations for floating the vessel. The superintendent of the Canal while present had told the pilot that he,wanted to get the vessel out of the canal as soon. as.possible. The captain regarded that as the understanding of all concerned-. The wreckers called out to the pilot: “ She is yours.” The pilot as-, sumed command and started to carry out-the superihtendent’s wish. Everybody at the time thought that' the; proper course, and we cannot think that the roaster was to blame for not overriding the. judgment of the local ex-' perts, with which his own concurred, on general grounds... On the other hand, as we have said, we agree with the Circuit Court of Appeals, and in any event we find that thé evidence recited by it shows that the Company.had notice-and that the master of, the vessel.ought, to have known that it was unsafe and improper to try to carry this vessel, .loaded as it was, through the canal. Both parties, therefore,- are responsible for all the damages including the loss of cargo and they should be divided between the two. The cargo owner, however, having proceeded only against the Canal Company, is entitled to a decree against that company for the frill amount. The Atlas, 93 U. S. 302. The New York, 175 U. S. 187, 209, 210.

Decree of Circuit Court of Appeals reversed,

Decree to be entered that the Northern >Coal Company recover its damages and costs from the Boston, Cape Cod & New York Canal Company; that the White Oak Transportation Company exonerate the Boston, Cape Cod '& New York Canal Company from .one-half of the above damages and- costs, and that the. damages and costs of the White Oak Transportation Compdny and the Boston, Cape Cod & 'New. York < Canal-Company be equally divided between those two companies.
