Only a few seconds long, there is a swing on a stage - you can't see from where it is mounted. One girl is on the swing and two other girls take turns pushing her in the swing. The stage appears to be painted to make it look like a natural setting - maybe out in a forest. This is when films were just images of real life - actualities they called them. This one has the probable added value of showing the petticoats of the girl as she swings toward the viewer, which was quite risque for the time. Normally, women would not be wearing this many petticoats, but in this situation it would have been considered indecent not to be wearing this many.
This can be easily viewed on youtube where you have the added entertainment value of reading comments arguing as to whether it was better to be alive in 1897 or now. I think it is odd to think that these young girls could have died before the end of WWII and still had pretty long lives, at least in reference to the time that they lived.
