var h3 = $('h3');
var text = h3.text().split(' ');

for( var i = 1, len = text.length; i < len; i=i+2 ) {
    text[i] = '' + text[i] + '';
}
h3.html(text.join(' '));

or

var h3 = $('h3');
var text = h3.text().split(' ');

$.each(text,function(i,val) {
    if( i % 2) {
        text[i] = '' + val + '';
    }
});
h3.html(text.join(' '));

To deal with & as you requested in your comment, I created an offset variable that is incremented whenever one is encountered.

var h3 = $('h3');
var text = h3.text().split(' ');
var offset = 0;

for( var i = 1, len = text.length; i < len; i++ ) {
    if( text[i] === '&' ) {
        offset++;
    } else if( (i-offset) % 2 ) {
        text[i] = '' + text[i] + '';
    }
}
h3.html(text.join(' '));
