Ian McTaggart-Cowan’s National Gold-award winning exhibit THE LAW STAMPS OF YUKON includes proofs, cancels and many interesting documents. A fabled part of the Canadian North, the Yukon includes the Rocky Mountains from the 60th parallel northward to the Arctic coast, and most of the headwaters of the Yukon River. In scenic terms it is spectacular and has attracted the attention many devotees of wilderness landscapes.The gold rush of the years around 1898 focussed the attention of the world on the Yukon. Due to an economic depression at the time, thousands of people flooded into central Yukon in search of instant riches. In just a few months the small settlement of Dawson found itself transformed into Dawson City, with a population of 40,000 people! The results were a much more complex society with many more aspects for historians and philatelists to study and report on.The author first visited Yukon some 50 years ago in his capacity as a Wildlife Ecologist and a member of the Arctic Institute of North America. His then early interest in philately was focussed on revenue stamps and their uses, particularly on the wealth of legal cases reflected in the documents validated by law stamps. The Law Stamps of Yukon were especially fascinating because the founding arrangement involved two series of stamps. One series was attached to a Gold Court charged with adjudicating disagreements within the mining industry. This court was very active for a period of eight years, after which the Territorial Court, responsible for everyday problems, handled most legal cases. The interesting Law Stamps of Yukon offer insight into many day-to-day events of times past.Ian McTaggart-Cowan has been involved in Canadian philately for many years. In addition to his Yukon exhibit he has also prepared a Gold-award winning exhibit of British Columbia Revenues. Ian has written many articles on revenue subjects as diverse as the Weights and Measures, Gas and Light inspection stamps of Canada, and Federal, Alberta and British Columbia Wildlife stamps.
