Crochet help needed

[liebschien.livejournal.com]

I am working on the crochet pattern found here and I have run into a bit of confusion.

I am beginning Row 17. It starts like this:

Row 17--Skip ch. 4, 1 long tr. in next long tr., work even to within 2 meshes of end, ch. 4; ...

What does "work even" mean?

Thanks for any help you can give.
