Henry Ernest Dudeney/Puzzles and Curious Problems/257 - Five Lines of Four

Puzzles and Curious Problems by Henry Ernest Dudeney: $257$

Five Lines of Four

The diagram shows how ten counters may be placed on the points of the grid where the lines intersect,

so that they form five straight lines with four counters in every line.

Can you find a second way of doing this?

Of course a mere reversal or reflection of the given arrangement is not considered different --

it must be a new scheme altogether, and of course you cannot increase the dimensions of the diagram or alter its shape.
