ships were subject to health quarantines, in particular for smallpox. Officials were sometimes too quick to declare a smallpox quarantine, which happened twice in July 1892 to Yosemite. Twice she was barred at Vancouver from landing passengers coming from Victoria and each time she simply landed them further up Burrard Inlet. Court action was necessary to persuade the Vancouver officials to allow Yosemite to land in their city. Purchase by Canadian Pacific Railway In 1901, the Canadian Pacific Railway purchased all the steamship operations and vessels of the Canadian Pacific Navigation Company, including Yosemite, which with other older steamers of the line was placed in reserve to fill in for newer ships taken out for service, and to cover times of high traffic such as in the summer months. By this time, Yosemite was almost 40 years old. Sale to Puget Sound excursion lines In 1906, the Canadian Pacific Railway sold Yosemite to the Puget Sound Excursion Company. This company had been organized by Capt. Thomas Grant to run cruises and excursions out of Seattle in connection with the Alaska–Yukon–Pacific Exposition. Once in Seattle, Yosemite was rebuilt somewhat by John B. Mitchell. The main deck and social hall were extended all the way forward to be flush with the bow, and a large dancing pavilion was installed. By the spring of 1907, Yosemite was in operation under command of Captain Grant, carrying up to 1,000 passengers at a time from Seattle to Bremerton and around Bainbridge Island. Music was provided by Wagner's Band and food service by Lord and Meeks, a well-known Seattle catering firm. The surviving photographs of Yosemite seem to always show an astounding number of people on her decks. This was in spite of the then recent loss of the in New York, also a wooden sidewheeler, in which over 1,000 people had been killed in a fire, and the resulting threat by the Puget Sound steamboat inspectors to strictly enforce the limits on passengers that could be embarked on excursions and cruises. Among other trips, in 1908, Yosemite carried almost the entire student body of the University of Washington out into Puget Sound to greet the Great White Fleet. In this particular trip, the vessel was obviously grossly overloaded, as the weight of the passengers caused her to heel so sharply over to port that the water came up to the bottom of the port side
