Judson Freeman Clark
Judson Freeman Clark (27 July 1870, Queens County, Prince Edward Island – 26 July 1942, Los Angeles) was a Canadian forester and mycologist. He is famous for publishing in 1906, what is now known as the International 1/8-Inch Log Rule (for 1/8-inch saw kerf), which he modified in 1917 for 1/4-inch saw kerf. (Herman Haupt Chapman (1873–1964) was the E. H. Harriman Professor of Forest Management, Yale University.) Biography After receiving a B.S. in agriculture from the University of Toronto in 1896, Clark taught English and mathematics at the Ontario Agricultural College from 1896 to 1898. In 1898 he matriculated at Cornell University, graduating there with A.M. in 1899 and Ph.D. in botany in 1901. At Cornell University, upon the resignation of Professor Filibert Roth, Clark was appointed assistant professor and, after six months' study in Germany and Switzerland, started work in January 1902. He "handled courses in timber physics, mensuration, dendrology, and silviculture." Cl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Queens County, Prince Edward Island
Queens County is a county in the province of Prince Edward Island, Canada. It is the largest county in the province by population with 89,770 (2021) and land. Charlottetown is the county seat of Queens County, and is the largest city and the capital of Prince Edward Island. The county is located in the centre of Prince Edward Island, and the geography varies from relatively flat plains to rolling hills in the central interior lands known as the Bonshaw Hills. The coastline features sandstone cliffs and sandy beaches, with numerous sheltered bays on the Gulf of St. Lawrence and Northumberland Strait. The most important geographic feature of Queens County is the Hillsborough River and its extensive estuary, which almost cuts both the county and Prince Edward Island in half. Queens County was formed in 1765, and was named by Captain Samuel Holland in honour of Charlotte of Mecklenburg-Strelitz, then queen consort of the United Kingdom. Historically the economy of the county ha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Girard Form Class
Girard form class is a form quotient calculated as the ratio of diameter inside bark at the top of the first 16 foot log to the diameter outside bark at breast height ( DBH). Its purpose is to estimate board-foot volume of whole trees from measurement of DBH, estimation of the number of logs, and estimation of the taper of the first log, based on the general relationships identified between the taper of the first log and the taper of subsequent logs. Girard form class is the primary expression of tree form in the United States. To allow for log trimming and a 1-foot stump height the diameter inside bark is measured at 17.3 feet above the ground. The closer the form class value to 100 the closer the log resembles a cylinder, where a value of 100 means the log is very nearly a cylinder. Volume tables using Girard form class are composite tables and are created independently of tree species. The volume tables may be corrected where systemic errors are identified, and modified GFC ...

Cornell University Faculty
Cornell University is a private statutory land-grant research university based in Ithaca, New York. It is a member of the Ivy League. Founded in 1865 by Ezra Cornell and Andrew Dickson White, Cornell was founded with the intention to teach and make contributions in all fields of knowledge—from the classics to the sciences, and from the theoretical to the applied. These ideals, unconventional for the time, are captured in Cornell's founding principle, a popular 1868 quotation from founder Ezra Cornell: "I would found an institution where any person can find instruction in any study." Cornell is ranked among the top global universities. The university is organized into seven undergraduate colleges and seven graduate divisions at its main Ithaca campus, with each college and division defining its specific admission standards and academic programs in near autonomy. The university also administers three satellite campuses, two in New York City and one in Education Cit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

University Of Toronto Alumni
A university () is an institution of higher (or tertiary) education and research which awards academic degrees in several academic disciplines. Universities typically offer both undergraduate and postgraduate programs. In the United States, the designation is reserved for colleges that have a graduate school. The word ''university'' is derived from the Latin ''universitas magistrorum et scholarium'', which roughly means "community of teachers and scholars". The first universities were created in Europe by Catholic Church monks. The University of Bologna (''Università di Bologna''), founded in 1088, is the first university in the sense of: *Being a high degree-awarding institute. *Having independence from the ecclesiastic schools, although conducted by both clergy and non-clergy. *Using the word ''universitas'' (which was coined at its foundation). *Issuing secular and non-secular degrees: grammar, rhetoric, logic, theology, canon law, notarial law.Hunt Janin: "The university ...

Canadian Foresters
Canadians (french: Canadiens) are people identified with the country of Canada. This connection may be residential, legal, historical or cultural. For most Canadians, many (or all) of these connections exist and are collectively the source of their being ''Canadian''. Canada is a multilingual and Multiculturalism, multicultural society home to people of groups of many different ethnic, religious, and national origins, with the majority of the population made up of Old World Immigration to Canada, immigrants and their descendants. Following the initial period of New France, French and then the much larger British colonization of the Americas, British colonization, different waves (or peaks) of immigration and settlement of non-indigenous peoples took place over the course of nearly two centuries and continue today. Elements of Indigenous, French, British, and more recent immigrant customs, languages, and religions have combined to form the culture of Canada, and thus a Canadian ...

Tree Taper
Tree taper is the degree to which a tree's stem or bole decreases in diameter as a function of height above ground. Within Forestry and for the purposes of timber production, trees with a high degree of taper are said to have poor form, while those with low taper have good form. The opposite is the case for open-grown amenity trees. The form of a tree is sometimes quantified by the Girard form class, which is the ratio, expressed as a percentage, of the butt-log scaling diameter to diameter at breast height Diameter at breast height, or DBH, is a standard method of expressing the diameter of the trunk or bole of a standing tree. DBH is one of the most common dendrometric measurements. Tree trunks are measured at the height of an adult's breast .... Taper is often represented by mathematical functions fitted to empirical data, called taper equations. One such function, attributed to Ormerod,Ormerod, D.W., 1973. A simple bole model.

Kerf
A saw is a tool consisting of a tough blade, wire, or chain with a hard toothed edge. It is used to cut through material, very often wood, though sometimes metal or stone. The cut is made by placing the toothed edge against the material and moving it forcefully forth and less vigorously back or continuously forward. This force may be applied by hand, or powered by steam, water, electricity or other power source. An abrasive saw has a powered circular blade designed to cut through metal or ceramic. Terminology * Abrasive saw: A saw that cuts with an abrasive disc or band, rather than a toothed blade. * Back: the edge opposite the toothed edge. * Fleam: The angle of the faces of the teeth relative to a line perpendicular to the face of the saw. * Gullet: The valley between the points of the teeth. * Heel: The end closest to the handle. * Kerf: The narrow channel left behind by the saw and (relatedly) the measure of its width. The kerf depends on several factors: the width ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Canadian International Paper Company
The Canadian International Paper Company (CIP) was a Montreal-based forest products company, a former subsidiary of International Paper. It was originally formed as the St. Maurice Lumber Company in 1919 but was renamed in 1925. It was sold to Canadian Pacific Forest Products in the early 1980s, which became Avenor Inc. in 1994; this company was then bought by Bowater in 1998. The company operated plants in Gatineau, Trois-Rivières, Témiscaming, La Tuque, Matane, Hawkesbury, Grand Falls and Corner Brook and Dalhousie, New Brunswick . This company set up the Gatineau Power Company which established hydroelectric plants on the lower Gatineau River. Now, these plants are operated by Hydro-Québec. The mill in Témiscaming was originally built by the Riordon Pulp and Paper Company, later bought by CIP. When CIP wanted to close its mill in this one-industry town, the employees formed Tembec Tembec Industries Inc., known as Tembec, was a paper company in Canada, founded by Fran ...

Crown Land
Crown land (sometimes spelled crownland), also known as royal domain, is a territorial area belonging to the monarch, who personifies the Crown. It is the equivalent of an entailed estate and passes with the monarchy, being inseparable from it. Today, in Commonwealth realms such as Canada and Australia, crown land is considered public land and is apart from the monarch's private estate. In Britain, the hereditary revenues of Crown lands provided income for the monarch until the start of the reign of George III, when the profits from the Crown Estate were surrendered to the Parliament of Great Britain in return for a fixed civil list payment. The monarch retains the income from the Duchy of Lancaster. Australia In Australia, public lands without a specific tenure (e.g. National Park or State Forest) are referred to as Crown land or State Land, which is described as being held in the "right of the Crown" of either an individual State or the Commonwealth of Australia; ther ...
