In August 1866, Dally accompanied the governor of Vancouver Island, Arthur Edward Kennedy, aboard HMS Scout on its circumnavigation tour of Vancouver Island with stops to inspect local villages. On the west coast, he only managed to produce two negatives, but on the eastern side he had better results, photographing at Fort Rupert, Comox, Cowichan, and Nanaimo. At Cowichan he took a pair of photographs of salmon weirs which are the earliest examples known. In a view taken in the same locality, the full range of Dally's compositional powers can be seen in his depiction of a Coast SalishQuamichan village. Two years later in 1868, he made a month-long trip up the Cariboo Road to the gold-rush town of Barkerville, photographing the route as well as the mining claims. The following year he returned to Barkerville, this time building a studio, only to see it destroyed a few weeks later in the fire that engulfed the town on September 16, 1868. Dally's manuscript is the only surviving written account of the disaster. Less than two months later he was back in Victoria, where he continued to photograph until September 1870 when he sold his gallery to the Green Brothers, a local firm. Sometime thereafter, his glass-plate negatives and probably his stock of prints passed into the hands of the Victoria photographers Richard and Hannah Maynard, who then sold Dally's images under their own imprints.
Later years
Dally left Victoria in 1870 to study dentistry in Philadelphia, and two years later, he returned to England where he practiced dental surgery until his retirement at age 71. His interest in British Columbia never waned, and he offered his expertise and collections to the Royal Geographical Society and the British Museum. In 1883 he presented an album of his British Columbia views to Queen Victoria. He died in Wolverhampton on July 28, 1914.
Reputation
Dally is considered to have taken some of the finest Canadian photographs of the 1860s, and in particular his work in the Cariboo goldfields and Barkerville is thought to be outstanding. According to the foremost authority on Dally, Joan Schwartz, "his visual record of the beginnings of British Columbia surpassed those of his contemporaries in artistic ability, technical skill and market appeal." Many of his views were used as the basis of engravings for the pictorial press, and his photographs of wagons being pulled by ten-mule teams over the Cariboo Road have been used to illustrate books on the history of British Columbia.
