They travel on foot over several weeks, visiting places such as Wilanów, Czersk, Puławy, Kazimierz Dolny, Janowiec, Zwoleń, Czarnolas, Iłża, the Świętokrzyskie Mountains, Chęciny, Kielce, Olkusz, and finally Ojców.

Along the way, they explore historical landmarks, collect "natural specimens", and experience various adventures (one of them falls into a dungeon, they are accused of theft, and are robbed by some Romani people).

[8] In 1896, Wiktor Gomulicki positively reviewed the book in Kraj [pl] magazine, praising the setting in Poland and writing that the adventures of the characters would "occupy our youth more than the English and Americans engaging in distant seas and lands".

The reviewer noted that young readers would "rightly be delighted by the adventures of their peers" in this "beautiful" and "exceptionally colorful and engagingly written" book, also praising the "interesting descriptions of places, events, and travel impressions, excellently captured and repeated".

The reviewer noted that the novel aimed to introduce readers to interesting Polish locations along with natural science information, but "the author only partially achieves this goal, as the detailed descriptions of architectural landmarks are dry and unengaging".
