THE TREE Basswood, or lime as it is known in Europe, is widely distributed in the northern temperate regions and is of commercial interest in the United States, Canada, Europe and eastern Asia. It comes from a medium to large-sized tree, usually about 20m in height, which is often grown for it's decorative effect in avenues and park settings. THE WOOD Basswood is a pale, almost white wood which darkens to pale brown on exposure. It has a straight grain and a fine and very uniform texture so that it is generally a featureless wood. It is of variable weight a mahogany, but American and Japanese timber is appreciably lighter, comparable to poplar. TECHNICAL PROPERTIES Basswood dries rapidly and well, apart from some tendency to distort, and once dry is moderately stable in use. It is not a strong wood; European lime has strength properties similar to those of sycamore, but the American and Japanese timbers are appreciably weaker. Basswood is noted for its excellent working properties, but it is redily attacked in conditions favoring decay. USES Basswood is one of the best woods for carving; it has long been used for this purpose and the remarkable detail that can be obtained is to be seen in the flower and fruit carvings of Grinling Gibbins, made in the late 17th century. Other traditional uses are for hat blocks and piano parts. It is also used for dairy and domestic utensils as it is free from taint and basswood is the preferred wood for beehive frames. Other uses are for small turned items, toys, bobbins and for scale lumber in the hobby industry.

THE TREE Yellow cedar is a timber of the Pacific coast region of North America from Alaska to southern Oregon. It comes from a tree of modest size in comparison with others in these forests, reaching 30m in height, with a trunk up to 1m in diameter. Found only on the Pacific coast of North America, Yellow Cedar is the hardest known cedar in the world. Only a limited amount of this wood is available every year. THE WOOD Yellow cedar is pale yellow and a little darker than Port Orford cedar and a little heavier than spruce. Prized by boat builders, it has exceptional resistance to weather and insects as well as easy workability. TECHNICAL PROPERTIES Yellow cedar dries well with little shrinkage, and once dry is noted for its stability in use. It is a moderately strong wood, stiff for its weight and with good shock resistance. It works easily and takes a good finish with both hand and machine tools. Like Port Orford cedar it is noted for its resistance to decay. USES Yellow cedar is an attractive, valuable but not very abundant wood, shipped in small quantities, mainly from British Columbia. It has many of the characteristics of Port Orford cedar and is used for similar purposes, in boat-building and for joinery and for furniture. It is an excellent wood for use out of doors; among its more specialized are engineers' patterns, surveyors' poles and it has always been considered one of the best woods for battery separators.

THE TREE Western Red Cedar is obtained in British Colunbia and parts of the northwestern United States from a tree which reaches 50m or more in height and 1 to 1.25m in diameter. A similar but commercially less important wood, eastern or northern white cedar, is produced by a smaller tree widely distributed in eastern parts of Canada and the United States. THE WOOD Western red cedar varies from pale pinkish-brown to dark brown. It is non-resinous, but has a fairly pungent odor, and is typically straight-grained with a conspicuous growth-ring figure. It is the lightest weight softwood in common commercial use; western red cedar is some 25% and white cedar 35% lighter than European redwood. The cellular composition of cedar, millions of tiny air-filled cells per cubic inch, provides a high degree of thermal insulation on both roof and wall applications. Western Red Cedars' slow growth and natural oily extractives are responsible for its decay resistance and its rich coloring, which ranges from a light straw color in the sapwood to a reddish pink in the heartwood. It is a stable wood that seasons easily and quickly, with a very low shrinkage factor. It is free of pitch and has excellent finishing qualities. TECHNICAL PROPERTIES Western red cedar dries quickly and well as thin boards, but thicker stock may be troublesome as it tends to collapse;, but once dry it is stable in use. A soft lightweight wood with correspondingly low strength, it is easy to work and takes a good finish provided that tools are kept sharp. Known for its extremely fine and even grain, its flexibility and strength in proportion to its weight, Western Red Cedar is a species of wood whose lumber can be used in a variety of ways. Western Red Cedar is renowned for its high impermeability to liquids and its natural phenol preservatives, which make it ideally suited for exterior use and interior use where humidity is high. USES Western red cedar is one of the most durable softwoods available in quantity, but being light in weight it is suitable only for uses where there is little structural need. It is seen most commonly as vertical cladding and weatherboarding, and is popular for garden buildings and greenhouses as well as a deck covering. It is used, especially in America, for roofing shingles, and lower grade timber is used in America for posts and piles.

THE TREE Yellow pine, or eastern white pine as it is known in America, is one of a number of species with lightweight which are known collectively as soft pines. Other commercially important soft pines include American western white and sugar pines and Siberian yellow pine. Yellow pine comes from a tree of medium size, up to 30m in height, with a trunk size of 60-90cm in diameter; it grows naturally in the eastern parts of Canada and the United States. Though it is occasionally seen elsewhere, its scope as a plantation tree is limited by its susceptibility to disease. THE WOOD Yellow pine is pale-yellow to bright brown, sometimes with a faint pinkish tinge. Growth rings, though present, are not well marked and the wood is noted for its fine, even texture and straight grain. It is light in weight, some 20% lighter than European redwood. Other soft pines are similar. TECHNICAL PROPERTIES Yellow pine dries quickly and is noted for its small shrinkage on drying and its stability in use. It is low in strength but works very easily, taking anexcellent finish. It is not resistant to decay. USES Yellow pine of good quality commands a very high price and is especially valued for engineers' patterns as it can be cut to give very fine detail and is remarkably stable in use. Other uses are for joinery, panelling, organ parts, drawing boards, wooden rollers, and in ship and boat-building. In America, a lower grade knotty timber is used for containers and packaging.
