in america here for visitors young and old unfolds a fascinating story of time and time telling the work of one man dr william barclay stevens dr stevens by again his collection with this early american wooden movement clock that was almost thirty years ago since then he has been a man with time on his hands a combination sun dial and compass from china is among the treasured exhibits representing many countries and dating back hundreds of years this german fourteenth century sandblast has four divisions marking one quarter  half three quarters and one hour columbus use an hour glass on his voyages to america early watches were so inaccurate that portable sun dials like this were carried to check them the sun dial was the first manmade timekeeper the oil clock gave light as well as time the lowering level of the burned mark the hour in the magill arms lock the door flipped open striking a match to help the sleeper find his the blind feel the time early watches range from one half ounce to almost two pound elephant clock illustrates the pendulum the most important single discovery in making the clock an accurate year is nineteen nineteen and this can be called america's first guided missile constructed barely sixteen years after the wright brothers first flight the crew craft had a forty one horsepower engine it was controlled by generous scopes and designed to carry two hundred aerial trailblazer followed a wobbly erratic course as it bubbled through the skies controlled by a nearby plane who could have dreamed that some day guided missiles would be built to span oceans and cross continent today an air force research centers the emphasis is not only on missiles but also on men the physical limits of a pilot must be known before us hurled into space by powerful rocket engines that is why volunteers risked their lives in safety test for american airmen machines out there limits to gear a piece of metal is dropped into a jet engine which in slow motion is ripped apart far cry from the old guided missile the new function it contains as many electronic elements as for television sets all crammed into the space of a copycat an air to air missile the fuckin reaches blinding supersonic speed in seconds the nose strikes through the target exploding its cargo of destruction with clinton of new york is dream changed america's destiny for he was the father of the erie canal the golden gate way to the west more than a century ago opened in eighteen twenty five erie canal was the first empire builder in our history it was the only water highway through the long appalachian mountain chain supplying a route for the settlers to go west it gave them a means for shipping their goods back east overnight the canal opened the east to the west and the west to the east in new york state towns rang up all along the five hundred mile route buffalo in albany the terminal cities grew rapidly and new york city began the greatest port city in the united states and eventually the world clinton's folly the critics called the inland waterway all wrong they were the erie canal became the thread that wall the far flung nation into a unified america achievement there were no roads to haul supply its builders had no previous engineering experience and only the crudest of tools and then cut through solid rock by hand and black powder building eighty two locks to overcome a difference of five hundred seventy one feet between the water level of the hudson river and lake erie it took eight years to complete it would remain in use some eighty years the task of replacing the old canal with a new waterway began in one thousand and five and continued for thirteen years the modern barge canal follows the picturesque pioneer route along part of its journey across new york state to at the eastern end of the new canal dramatizes the change from nineteen to twenty a century barge travel operated by electricity each of the fifty seven locks can raise or lower a vessel in twenty minutes the giant steel gates can be opened in thirty seconds there is room for any of us all up to three hundred feet in length the depth of the waterway has been lowered from four to twelve feet now barges carrying up to a thousand tons of cargo can make the canal boy haired stretches of broad fresh level of water a highway that since the air is opening has been the main track of america's commercial development the junction of the hudson and mohawk rivers single all made possible the conquest of the allegheny divide the original canal utilize the mohawk valley the middle link between the great lakes and the hudson falls is typical of the city that sprang up with the canals completion and became busy centers of trade in the twenty years after the area's opening new york's population almost double the empire state had been born each lock is three hundred twenty eight feet in length forty five feet in width and up to fifty feet in height with all its branches the erie canal is nine times longer than the panama canal in one stretch of two miles the waterway drops one hundred sixty nine feet through five locks this is the most remarkable flight of locks in the world but the transformation along the banks of the erie was even more spectacular thomas jefferson had said to talk because making a go now three hundred fifty miles through a wilderness is little short of madness in this day today special riding smoothly through the step up at lockport symbolizes the dreams  them on still america was catching for the first time a sweeping love got into a limitless future
