jQuery Simple Animation, restart when finished

In the attached code, I am animating a div from left to right.  How can I animate it every three seconds, then restart when it's reached the end (so it looks seemless)?

HTML:
            <div class="frame">
                  <div class="subframe">
                        <div id="slide" class="slide" style="margin-left: 0px;"><span>Lorem ipsum</span><br />dolor lorem</div>
                  </div>
            </div>

CSS:
                  .frame { overflow: hidden; width: 468px; height: 60px; background: url('bg2.jpg'); }
                  .subframe { width: 309px; overflow: hidden; }
                  .slide { font-family: arial; font-size: 14px; padding: 5px; margin-top: 8px; text-align: center; width: 309px; line-height: 18px; }
                  .slide span { font-weight: bold; font-size: 16px; }

Javascript:

$(document).ready(function() {
	$(function(){
		$("#slide").animate({marginLeft:'+=309px'},{ duration: 1000, queue: false });				   
	});
});

Thank you but it doesn't seem to restart, it just stays where it is moved.  I want to scroll three different texts.  Probably, three DIVs inside the "#slide" div.

okay in the animate method, reset the margin left


$(document).ready(function() {
       
      animate();
});

function animate()
{
            $("#slide").css("marginLeft","0px");
            $("#slide").animate({marginLeft:'+=309px'},{ duration: 1000, queue: false }, function(){
                      animate();
               });                              
}
