The year 2020 is a hundredth anniversary of historical factsdescribed in this book. InvocationPoland Mother, you are the song and brightness of hearts.Poland ornamented with forests at the lakes' waters -vastness of prairies with the ribbons of shinning rivers.Above mountain pastures are your monumental mountains, your crowns, below are dales and meadowsornamented with flowers.There is gold of rye and early Autumns -melancholy of alleys of bifurcate willows.
