### Dutchmen's Three Wives

There came $3$ dutchmen of my acquaintance to see me, being lately married;
they brought their wives with them.
The men's names were Hendrick, Claas, and Cornelius;
the women's Geertrick, Catriin, and Anna;
but I forget the name of each man's wife.
They told me that they had been at market, to buy hogs;
each person bought as many hogs as they gave shillings for each hog;
Hendrick bought $23$ hogs more than Catriin,
and Claas bought $11$ more than Geertrick;
likewise, each man laid out $3$ guineas more than his wife.
I desire to know the name of each man's wife.

### Hour and Minute Hand in Straight Line

"Being at so large a distance from the dial-plate of a great clock, that I could not distinguish the figures;
but as the hour and minute hands were very bright and glaring,"
the correspondent noted that they were in a straight line and pointing upwards to the right.
It was evening.
What was the time?

## Historical Note

Started life as a women's interest magazine, but evolved into a magazine of riddles, puzzles and mathematical questions.

In its later years, many of the questions published therein were difficult, and attracted the attention of high-profile mathematicians of the time.

Many questions it published were ancient. For example:

Question $42$ was a variant of Chiu Chang Suann Jing: Example 8.
Question $51$ was taken from Diophantus of Alexandria: Arithmetica Book $\text {V}$.

It was also frequently the case where the questions were taken directly from published sources, sometimes even mathematics textbooks.
