After the Civil War the domination of the "political machine" over the affairs of government in the urban cities of the north became an undisputed fact of local politics. Their power flowed from creating a form of government that sought to perpetuate the position of its leaders by engaging in a bartering process with voters. The political machine existed during a time of mass migration to our urban centers from both immigrants and those in search of work. It played upon the ethnic composition of

GRINDING MACHINES Grinding is the process of removing metal by the application of abrasives which are bonded to form a rotating wheel. When the moving abrasive particles contact the workpiece‚ they act as tiny cutting tools‚ each particle cutting a tiny chip from the workpiece. It is a common error to believe that grinding abrasive wheels remove material by a rubbing action; actually‚ the process is as much a cutting action as drilling‚ milling‚ and lathe turning. The grinding machine supports and

The Time Machine The history of this short novel is imformational. It shows Wells developing and exploring the idea consistently over several years‚ as his rate of production would restrain him from ever doing again. In many ways‚ The Time Machine is his most complete work; a thorough development of the Darwinian ideas he had absorbed at the Normal School of Science and that would form the bedrock of everything else he did throughout his career.

Time Machine If I had a time machine and could bring back one person from the past I think it would be the singer Left Eye. I would bring her back so I can interview her because before she died I didn’t really believe in spirits coming after you until it happened to her. I think the way she died was really scary and I would like to ask her about how she went thru everything with knowing that spirits were after her. If I was to bring Left Eye back the first thing I would do bring her to her family
