Puzzles and Curious Problems by Henry Ernest Dudeney: $308$

Domino Hollow Squares

It is required with the $28$ dominoes to form $7$ hollow squares, like the example given,

so that the pips in the four sides of every square shall add up alike.

All these seven squares need not have the same sum, and, of course, the example given need not be one of your set.
