"I regret to have to record the death of Mr. W.F. Ratz which occurred in Ottawa on February 6. Mr. Ratz had been employed on the Alaska survey since 1905. He carried out demarcation of the line at [Tsirku] river (Chilkat district), and in part between Taku inlet and Whiting river. During the last two years he was engaged on the topographical survey between Whiting and Stikine rivers, not the least difficult section of a very difficult survey. His success in carrying this to completion in a relatively short time is a testimony of his capability as a surveyor as well as to his personal energy. His death, at the early age of 25, is a serious loss to the profession and to the public service."
