The first photo is the title page in a book first published by the Victorian government in 1928-9 revised substantially in 1940 & reprinted as the second series from which the photos are taken.
The simple short story is of two men arguing rightful ownership of a found oyster. You can read the full story in photo 2.

The education that I have just received from reading the story & ascertaining the proprietorship is that the Victorian government wants its citizens indoctrinated into the following beliefs:

1. A lawyer will rob you.
2. The government & court is powerless to prevent this robbery.
3. Government is another form of robbery immune from prosecution.
4. Half an oyster in the hand is better than only one half of empty shell.
5. Government indoctrinates citizens into not creating problems for the government.
