- Description
- An 'automatic' telegraph key with a heavy, rectangular, metal base. The bottom of the base has tripod, stubby feet and two narrow copper strips attached with screws to fittings at the top. JEP is inscribed on the side of the platform.
The lever key and fittings on the top are silver-colored metal. The key has a black, round, flat knob at one side, the end is a black, triangular piece on the other side. Below and to the side of this is a small lever (on/off switch?) with a cylindrical, red knob at the top. The key, which runs the length of the base is attached to a square metal holder near the font of the base. This square piece has "78" stamped at the bottom center. The key is attached to it with several different fittings.
At one side is a short (approx. 60cm) length of tan, cloth-wrapped wire. The wire has a black, cylindrical grip and a pointed copper plug at one end. The other end is divided into three wires which are connected to fittings on the base.

- History / Biographical
- As a result of the Klondike Gold Rush, the Yukon Telegraph Line was established to link the rest of Canada with the Yukon. The Line was an overland telegraph operated by the Dominion Government of Canada from 1901 and 1936. Telegraph service previously existed up to Hazelton with the Collin’s Overland Telegraph (1866), which was built by the Western Union Telegraph in hopes of linking Europe and Canada via the Bering Strait and Russia. However, with the Transatlantic Telegraph Line was completed first, construction on the Collin’s Overland Telegraph was halted just north of Hazelton.
In 1899 or 1900, the Dominion Government of Canada began construction north of Hazelton (which at the time was undeveloped and remote), using a combination of old Collin’s Overland Telegraph surveys, First Nations trails and the Ashcroft Trail. In 1901 the telegraph began operation, employing one lineman and one operator at each station cabin along the route. There were nine main cabins along the route numbered 1 to 9. Beyond the Ninth Cabin, the stations were named based on nearby geographical features, such as Echo Lake or Iskut River. In between each “home stations” were refuge cabins, referred to by distance from the main cabins in the reports by linemen.
Most of the records held by the Archives pertain to the Eighth Cabin, of which Charles Philip Janze maintained the northern lines and John Jensen serviced the southern portions of telegraph line. William Blackstock most likely maintained the Ninth Cabin and its surrounding lines. Unfortunately, in 1936, substantial flooding severely damaged sections of the telegraph line and supporting infrastructure, and with the emergence of new wireless radio technology, the Dominion Government could not justify spending the money for repairs and the Yukon Telegraph Line was permanently shut down.

- Narrative
- From the Kispiox area
- History Of Use
- Insulators kept the wires linking telegraphs insulated from the wooden poles that held them aloft. Insulators can be dated by looking at material that they are made of, and how they were manufactured. The earliest insulators were made of glass, and were first made in the 1840s. Threaded glass insulators were patented in 1865 as a means of more securely fastening the glass to the wood pins (like a bottle and its cap). Porcelain and ceramic insulators, which were found to have superior protective properties, came into use in the late 1800s.
- Cultural Context
- The Russian–American Telegraph, also known as the Western Union Telegraph Expedition and the Collins Overland Telegraph, was an undertaking by the Western Union Telegraph Company in 1865–1867, to lay an electric telegraph line from San Francisco, California to Moscow, Russia. The route was intended to travel from California via Oregon, Washington Territory, the Colony of British Columbia and Russian America, under the Bering Sea and across Siberia to Moscow, where lines would communicate with the rest of Europe. It was proposed as an alternate to long, deep underwater cables in the Atlantic. The line was abandoned in 1867. Source: Wikipedia

- Description
- A rubber telegraph insulator. It has a cylinder-like body, ending in a dome top. Between the cylinder body and the dome head is an groove measuring approx. 1.5 cm in width.
See http://www.collectinginsulators.com/Rubber/Rubber.html for more information, including:
"Few references contain information on rubber insulators. Gerald Brown's book on nonglass/nonporcelain insulators is probably the lone exception, however, this was published many years ago and is out of print. Even then, there was only surface coverage of the various markings on rubber insulators
There are several reasons for the lack of interest in rubber insulators:
Limited number of styles. Continental Rubber Works catalog four styles of rubber insulators: The R-3, R-4, R-5 and RC-1. An unmarked, unattributed slot-topped rubber insulator can also be commonly found. Some early hard rubber pin-type insulators made around 1861 exist and ruber was used in making several styles of hooks. This brings the number of styles to around a dozen
Boring colors. It is no wonder that glass insulators are so popular with their range of colors that can be backlit. Rubber insulators, on the other hand, are exclusively black.
Excessive supply. Continental Rubber Works made 50,000 rubber insulators per year in the 1970s with production probably extending back to the early 1940s. Since these are more recent insulators, they tend to be the ones still on the poles when they the poles came down rather than being the ones that were carted away to the landfill years ago as some newer style replaced them. The exception to this is the earlier hard rubber and hook styles which are rare.
There are two groups of patents that are relevant to rubber insulators:
Patents by Nelson and Charles Goodyear on the process of making rubber. These include patents #3,461, #3,462, #3,633, #4,005, #4,099, #8,075 issued May 6, 1851 and #25,111. The May 6, 1851 date has been found on a hard rubber hat style insulator.
Patents assigned to The Western Union Telegraph Company under which Continental Rubber manufactured their insulators. These patents include #2,218,497 issued October 15, 1940, #2,304,483 issued December 8, 1942, and #3,061,667 issued October 30, 1962."Using this website, one can see that 5-B molds were associated with patent number 2304483.

- "5 - B" is on the dome end of the insulator, just above the groove.
