         on this sontinent a new nation,conceived in liberity,
            and dedicated to the proposition that all men are created
            equal.
        </p>
        <p>Now we are engaged in a great civil war,testing whether
            that  nation, or any nation so conceived and so didicated,
            can long endure,We are met on a great battlefield of
            that war, We have come to dedicate a portion of that
            field as a final resting-place for those who here gave
            their lives that the nation might live,it is altogether
            fitting and proper that we should do this .But,in a larger
            sense,we cannot dedicate,we cannont consecrate,
            we cannot ballow,this ground.       
        </p>
        <a href="#" class="more">read more</a>
          <p>The brave men,living and dead,who struggled
                here have consecrated it,far above our poor
                power to add or detract,The world will little
                note,nor long remember,what we say here,but it
                can never forget what they did here.it is for us
                the living,rather,to be dedicated here to the
                unfinished work which they who fought here have
                thus far so nobly advanced
          </p>
          <p>It is rather for us to be here dedicated to the
                 great task remaining before us-that from
                 these honored dead we take increased devotion to
                 that cause for which they gave the last full
                 measure of devotion-that we here highly
                 resolve that these dead shall not have died in
                 vain-that this nation,under God,shall
                 have a new birth of freedom and that government
                 of the people,by the people,for the people,
                 shall not perish from the earth.
