Anyone know of any good reading material on the meaning of the Ashlar cube in Freemasonry?

Been trying to find something in depth for me to really stick my teeth into and was hoping some of you guys might know of some good reading material about it.

That site explains it.

Proud to say, I have those in book form from the 1800s....when I became a Mason, I inherited my grandfather's copies.

You need to get to the third to get the answer to that but in all honesty your provincial grand lodge or grand lodge depending on where you live should stock some reading on each stage as you go through each degree which you can order and it also helps out your brethren who produce these.
