Paragraph 42. Poplar is sometimes known as whitewood or tulip, but in the lumber form is more often spoken of as yellow poplar. It was once one of our principal timbers of commerce. Only a few years ago large poplar trees were abundant and poplar boards could be had in almost any width. The wood is very soft and easily worked, has a fine texture, straight grain, light of weight, of a light-yellowish color, without a very pronounced grain. It checks but little in drying, does not warp badly and is one of the most durable woods for outside exposure. It has been abundantly used for weatherboarding of houses and other construction work where it is exposed to weather conditions. On account of the scarcity it is no longer used in larger construction work, but is used almost exclusively for paneling and in the making of drawers and other inside work in cabinet construction.
