The Most Common North American Spruces
A spruce is a tree of the genus Picea, a genus of about 35 species of coniferous evergreen trees in the Family Pinaceae, found in the northern temperate and boreal (taiga) regions of the earth. In North America, there are 8 important spruce species most important to the timber trade, the Christmas tree industry and to landscapers. Spruce trees grow at either high altitudes in the southern Appalachians to New England or at higher latitudes in Canada and the higher elevations of Pacific coastal mountains and the Rocky Mountains. Red spruce occupies the Appalachians into upper Northeastern states and provinces. White and blue spruce trees mainly grow throughout most of Canada. Englemann spruce, blue spruce, and Sitka spruce are native to the western states and Canadian provinces. Note: Norway spruce is a common non-native European tree that has been extensively planted and has naturalized in North America. They are primarily found in areas of the Northeast, the Great Lake States and Southeastern Canada and the best are cut for New York Citys Rockefeller Center annual Christmas Tree. Identification of the Common North American Spruce Trees Spruces are large trees and can be distinguished by their whorled branches where needles radiate equally in all directions around the branch (and look very much like a bristle brush). The needles of spruce trees are attached singly to the branches sometimes in a spiral fashion. On firs, there is a distinct lack of needles on the bottom side of its twig, unlike spruces that carry needles in a whirl all around the twig. In true firs, the base of each needle is attached to a twig by a structure that looks like a suction cup. On the other hand, each spruce needle is situated on a small peg-like structure called a pulvinus. This structure will remain on the branch after the needle drops and will have a rough texture to the touch. The needles (with the exception of Sitka spruce) under magnification are clearly four-sided, four-angled and with four whitish stripe line. The cones of spruce are oblong and cylindrical that tend to be attached to limbs mostly at the top of the trees. Fir trees also have similar looking cones, primarily at the top, but tend to stand upright where spruce hangs downward. These cones do not drop and disintegrate attached to the tree twig. The Common North American Spruce Red spruceColorado blue spruceBlack spruceWhite spruceSitka spruceEnglemann spruce More on Spruce Trees Spruces, like firs, have absolutely no insect or decay resistance when exposed to the outside environment. Therefore, the wood is generally recommended for indoor housing use, for sheltered support framing and in furniture for cheaper structural construction. It is also used when pulped to make bleached softwood kraft. Spruce is considered to be a significant North American timber product and the timber trade gives it names like SPF (spruce, pine, fir) and whitewood. Spruce wood is used for many purposes, ranging from general construction work and crates to highly specialized uses in wooden aircraft. The Wright brothers first aircraft, the Flyer, was built of spruce. Spruces are popular ornamental trees in the horticultural landscaping trade and enjoyed for their evergreen, symmetrical narrow-conic growth habit. For the same reason, non-native Norway spruce is also extensively used as Christmas trees.

American Music Legends Hank Williams Volume 2 by Hank Williams free essay sample
This album is one of the greatest albums to hit the market. It is good old fashioned music and has a good meaning in every song. Each song has plenty of twang that any country boy would love to hear. Hank Williams has produced so much great over the years and this album definitely lived up to our expectations. Some of the hits on the album include, â€Å"I saw the light†and â€Å"Hey good looking†. They each have a good tempo and make you want to stand up and dance away whenever they come on. The quality of the songs on this album is very high and is even better than some of his previous albums. However, I do not believe they put very much thought in the order of which they put the songs on. This is the one and only downside to this album, they should have thought that through better. We will write a custom essay sample on American Music Legends Hank Williams Volume 2 by Hank Williams or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page They could have ordered it so the songs had more of an emotional appeal. In my honest opinion, I would recommend this album to any country music-liking person. It has a good American patriotism in it that surely attracts many. If you don’t like country music I would not recommend it though, it is very much country. The people who will enjoy it the most are rednecks and people who live a very rural life. Most people who do not live this life will not enjoy/appreciate it. I believe it was very well priced also based on the price of an average song on the market up for download today.
