Using express to extend extrene signal, can I use a secont express to extend first express (extending extrene)signal even further

Question

I'm extending the signal of Airport Extreme with an Airport Express. However, I still need to to extend signal even further.
Can I use another Airport Express to extend the signal of the firts Aiport Express even further which is already extending the signal of Airport Extreme?
In other words, Airport Extreme connected to Airport Express extending signal, then another Airport Express extending signal from first Airport Express.

Bob,
Thanks for answer this... I am trying to figure out how to do something in my home and thought you might be able to answer this for me.  I have a house that has wired ethernet thruout.  I have a  dual t1 line coming into a wired router (that provides internet access) going into a switch.  Plugged into the switch are all the ethernet lines running thruout the house and a wireless apple time capsule.  I have 3 other apple extreme base stations that I want to plug into the wired ethernet connections thruout the house and have all of them use the same base network... Right now when I go thru the wizard it sets them up to connect via the wireless signal, which is great if they are within range of the time capsule, but the second I move one of them to another area of the house that is outside this range, they "appear" to be working (green light) but are actually not connecting to the time capsule, whether or not I plug them into the ethernet jack or not....  I can assign each one of them a separate static IP address that allows each of them to reach the internet but then I will have 4 wireless networks rather than just one... Hopefully, I explained this well... Any suggestions?
Thanks!
Jim
