Wood chips come from the interior of a tree. This mulch is available as hardwood or softwood, or as a mixture. Hardwood mulches, according to Fine Gardening, will last a little longer than softwood mulches. Wood chips, in general, do not last as long in the landscape as bark mulches.
There have been more Republican presidents than Democratic presidents. Between 1789 and 2013, 43 people have been sworn into office as the president of the United States of America. Of these, a larger number have belonged to the Republican Party than have belonged to the Democratic Party.
Abraham Lincoln was the first president who was a member of the modern Republican party. Some sources, particularly simplified charts, describe earlier presidents as being republican, but that was a different and not directly related party, which was formally called the Republican Democratic party.
