Taxonomy is the science of classifying organisms. The system currently used by taxonomists is called the Linnaean taxonomic system, in honor of Swedish biologist Carolus Linnaeus (1707 â 1778). The Linnaean system breaks down organisms into seven major divisions, called taxa (singular: taxon).

Can you stack the block with a tractor or by wheel barrel. I recently completed a Keystone Legacy wall (60 face feet) which block is 6 inches high and 16 inches wide. This was done on a compacted base. The wall had to be put in next to an existing fence that was covered with up to 30 inches of dirt. The purpose was to correct dirt being back filled against the wood.
