Mackayâs pioneers featured in early account of our history An excerpt from The History of Queensland, it's People and Industries, compiled by Matthew Joseph Fox. Picture: Greenmount Homestead. News Vicky Bowden, Greenmount Homestead 10th Jun 2021 5:00 AM When I was a child growing up in the early â70s, I remember the door-to-door salesmen who used to come around trying to sell encyclopedias â in particular, the Encyclopedia Britannica. Often this was offered on a subscription basis â taking one volume a month over a period of time â often a couple of years. That particular publication has been around in various forms since 1768; now in its 15th edition as an online only version.
