Both vessels are sisters and, therefore, a description of the Colorado will answer for that of the Pennsylvania. OBITUARY In speaking of the death of John Bertram of Toronto, Capt. Thomas Donnelly of Kingston, Ont. said: "Everyone interested in the transportation interests of this country must deplore his death. At the time he was appointed chairman of the transportation commission it was thought by many that John Bertram had not a sufficient knowledge of the transportation interests of Canada to warrant the govern- ment entrusting him with such an important commission, but he brought to the task an experience and ability which soon proved to every one interested that he was the right man in the right place. It was evident to everyone that he entered on his duties with an unbiased judgment, anxious to THE ARMORED CRUISER COLORADO listen care- fully to the case as pre- sented by all the in- _terests con- cerned, and I feel sure that his re- port to the government would have been of Vetye "oreat value to the transpor t a- tion _inter- ests of this Co th fry. Early in the year I had the _ pleas- ure, in com- pany with other mem- bers of the Dominion Marine Association, of accompany- ing Mr. Betram to Buffalo, in connection with the changing of the Canadian rules of the road, and I am sure no one present on that occasion will soon forget the evidence which Mr. Bertram then gave of his knowledge and ability. He possessed a fund of general information and any one fortunate [Butlt by Cramps, Philadelphia. enough to meet him was sure to be benefited thereby." The report of the chief of the bureau of construction and repair of the navy department announces that the 450-ft. collier for the United States navy will be constructed at the Mare Island navy yard. Work will be begun during the 'fiscal year and estimates for improvements to cost about $232,- 500 are submitted. $50,000 is required for a new machine- shop and machinery; piers are to be built between the en- trances of docks No. 1 and No. 2, so as to provide for the satisfactory berthing of vessels under repair. Building No. 53 is to be remodeled so as to provide for the storage of steel and for a mold-loft, at an estimated cost of $73,000; and the electric workshop is to be enlarged. It is recommended that a fire-proof building for the storage of boats and furniture be erected on the site that will be available after the re- moval of building No. 98. The rebuilding of the Marine rail- way is said to be necessary. Some highly successful experiments with the British sub- marine Br have just been completed at Barrow-in-Furness. This submarine, which was launched at Barrow early in the month, is of a new type, and much larger than any submarine yet built. Sie possesses all the improvements which science and experience with other boats has suggested. She was taken out to deep water outside Barrow harbor and there went through a long series of exhibitions with the greatest possible success, and without the slightest hitch. She re- mained under water at one time for over three hours and caused some apprehension on board of the tugboat which was in attendance, but she ultimately floated to the surface some two miles away and-reported she could have stayed down a much longer time. The great success of these experiments has delighted the admiralty representatives who were present, and it is expected that orders will forthwith be given out for additional vessels of this type.
