Pit Prop
A pit prop or mine prop (British and American usage, respectively) is a length of lumber used to prop up the roofs of tunnels in coal mines. Canada traditionally supplied pit props to the British market. As coal mining declined in importance and metal supports were used, the term became infrequently used. Though it was merely a log cut to a particular length, it was classified as a finished product and so got around the extra Canadian tariffs on the export of raw lumber. Because of the large quantities exported, it is probable many ended up in British pulp mills. Most pit props were made from the wood of spruce A spruce is a tree of the genus ''Picea'' ( ), a genus of about 40 species of coniferous evergreen trees in the family Pinaceae, found in the northern temperate and boreal ecosystem, boreal (taiga) regions of the Northern hemisphere.

Standard (timber Unit)
A standard or standard hundred was a measure of timber used in trade. The measure varied in number, size and composition from country to country so the term is usually preceded by the region or port of origin. The countries of the Baltic region were major producers and exporters of timber, and used their local measure for trade with other countries such as Britain. The ''hundred'' in the term ''standard hundred'' was usually a '' long hundred'', meaning 120 pieces, but the word ''hundred'' was often dropped, leaving simply ''standard'' to mean "the local standard number of pieces, each in the local standard dimensions". The timber would be typically called battens (7 inches wide), deals (above 7, usually 9 inches wide) and planks (11 inches wide); boards were under 2 inches thick. The standard hundred of the Russian capital of Saint Petersburg was 120 boards which were 12 feet long, 1 inches thick and 11 inches wide – a volume of 165 cubic feet. The city changed its nam ...
