I don't have that book, so I'm just guessing what you are asking.
Only found references to it online, but no sources online. 

I assume you have the varient of a 66 block that has 4 pins across,
with the left two pins solid, and the right two pins solid.
(ie. a split 66M) that is most common. 

Most people aren't using bridge clips now-a-days to make a connection
from left to right, as done in the ancient days of telco-dom. 

But usually they just use both sides of the 66-block to terminate wires of
the same function.
As the come inbound, they'd be located on the outer pins on both sides.

Then to connect to it, you'd run cross-connect pair from the inner
pins of the solid two (from whichever side) off to the block/wires
you are cross-connecting to on the inner pins.

Ie. lets see if I can make an ASCII picture.

    Co Trunks          Stations


So, you have your stations punched down on the outer pins of the
station block down both sides, and you have your trunks punched down
on the Outer pins of the CO block. You'd cross connect pr1 on the
Inner pin to say the Inner pin no the station block of whatever pair.

If this doesn't help, maybe the site
http://www.homephonewiring.com/blocks.html
can show you better.
